Might work pretty good for plumbing flux too. Disposable brushes are nice,
but it just feels like such a waste when you're only doing two joints.

I'll have to look for those. How much does the silicone flex?

Puckdropper

Quite a bit. They have approximately 30 little fingers that are about
3/4" long.

Silicone is the latest rage in cookware. I have a couple of brushes like
yours for basting, buttering, etc. We also have some spatulas, stirring
spoons, etc. We haven't tried any of the muffin tins or cake/loaf pans, but
I keep thinking about it. I see them used on the cooking competition
shows all the time. The food items just pop right out, like a ice from
a plastic ice cube tray.
Well for baking silicone has been around for quite a while, at least
10~15 years. I bought my wife silicone muffin tins, bread pans. She
pretty much hates them. So they tend to break down and become sticky
over a period of time. What ever is oozing out is oozing out in high
temperatures into your food.


Are you talking about 15 YO muffin tins or modern day muffin tins?
Well since she had the bad luck she has not bought any more hoping that
it got better.


Compounds have probably improved.

Maybe but they are still silicone unlike the examples you mentioned below.


On the other hand, it's possible that one might confuse a sticky residue from the
food with the breakdown of the silicone. Like I said, I've not tried any silicone
bakeware, so this may not be what you and the missus have experienced. I can
say that I have experienced sticky residue on metal cookware over time.
No, the silicone bakeware was put up clean and developed this
deteriorating sticky goo sitting in the dark of the cabinet.
Trying to clean that goo off damaged the surface.

I was gluing on some edging last night and got to thinking about the
silicon brushes vs. silicon muffin tins.

I'm just tossing this out, not trying to prove my point. It's just a possibility.

In this response you said:

" the silicone bakeware was put up clean and developed this
deteriorating sticky goo sitting in the dark of the cabinet."

In another response, you said:

"Ambient room temperature being the relative constant and the
silicone breaks down on its own. Oddly, the silicone brush and
small silicone container have not exhibited this condition."

OK, so what's different between these two situations? One obvious
difference is the use of oil and other food stuffs when baking but
not when gluing.
Sooo the really big difference is the high heat that the baking dishes
are exposed to.

It could be possible, that based on the articles I quoted, the muffin
tins only felt clean when put away but the unfelt residue eventually
changed it's chemical structure (polymerized, perhaps?) and turned
sticky.
What ever is going on, the silicone baking pans, heat breaking down the
silicone or residue from baking not actually coming off in the
dishwasher but still feel clean we choose to not risk the possibilities
of what was going on.

I've had cast iron skillets turn sticky if not used frequently enough.
Granted, they are put away with a slight coat of oil on them, but it
could be possible that the silicon muffin tins also had a very slight
amount of residue, even if cleaned as thoroughly as possible before
being stored.
Possibly but then they fail because they do not come clean and the
silicone breaks down.

The way to test that would be to put the brushes - or at least the bristles -
through the same cooking and cleaning process and see if they eventually
get sticky.
They probably would. But our silicone utensils, if not exposed to high
heat, baking, hold up with out getting sticky.


Either way, our experience with the silicone after being baked was not a
pleasant one compared to the metal equivalents.

Gotcha! Makes sense.

The things you think of while waiting for glue to dry. ;-)

Aren't these silicone utensils all dishwasher safe? If so, I'd try
diswashing them to remove the varnish film. You may need a
phosphate-bearing detergent, as used in commercial establishments.

I don't think that silicone rubber needs or has plasticisers.

The knobs may not be silicone rubber. It may be depolymerizing. With
urethane rubbers, this is called "reversion".

One can tell by burning a sliver of the rubber. If silicone, the char
will be sand, not carbon.

Silicone is the latest rage in cookware. I have a couple of brushes like
yours for basting, buttering, etc. We also have some spatulas, stirring
spoons, etc. We haven't tried any of the muffin tins or cake/loaf pans, but
I keep thinking about it. I see them used on the cooking competition
shows all the time. The food items just pop right out, like a ice from
a plastic ice cube tray.
Well for baking silicone has been around for quite a while, at least
10~15 years. I bought my wife silicone muffin tins, bread pans. She
pretty much hates them. So they tend to break down and become sticky
over a period of time. What ever is oozing out is oozing out in high
temperatures into your food.


Are you talking about 15 YO muffin tins or modern day muffin tins?
Well since she had the bad luck she has not bought any more hoping that
it got better.


Compounds have probably improved.

Maybe but they are still silicone unlike the examples you mentioned below.


On the other hand, it's possible that one might confuse a sticky residue from the
food with the breakdown of the silicone. Like I said, I've not tried any silicone
bakeware, so this may not be what you and the missus have experienced. I can
say that I have experienced sticky residue on metal cookware over time.
No, the silicone bakeware was put up clean and developed this
deteriorating sticky goo sitting in the dark of the cabinet.
Trying to clean that goo off damaged the surface.

I was gluing on some edging last night and got to thinking about the
silicon brushes vs. silicon muffin tins.

I'm just tossing this out, not trying to prove my point. It's just a possibility.

In this response you said:

" the silicone bakeware was put up clean and developed this
deteriorating sticky goo sitting in the dark of the cabinet."

In another response, you said:

"Ambient room temperature being the relative constant and the
silicone breaks down on its own. Oddly, the silicone brush and
small silicone container have not exhibited this condition."

OK, so what's different between these two situations? One obvious
difference is the use of oil and other food stuffs when baking but
not when gluing.

Sooo the really big difference is the high heat that the baking dishes
are exposed to.


It could be possible, that based on the articles I quoted, the muffin
tins only felt clean when put away but the unfelt residue eventually
changed it's chemical structure (polymerized, perhaps?) and turned
sticky.

What ever is going on, the silicone baking pans, heat breaking down the
silicone or residue from baking not actually coming off in the
dishwasher but still feel clean we choose to not risk the possibilities
of what was going on.



I've had cast iron skillets turn sticky if not used frequently enough.
Granted, they are put away with a slight coat of oil on them, but it
could be possible that the silicon muffin tins also had a very slight
amount of residue, even if cleaned as thoroughly as possible before
being stored.

Possibly but then they fail because they do not come clean and the
silicone breaks down.



The way to test that would be to put the brushes - or at least the bristles -
through the same cooking and cleaning process and see if they eventually
get sticky.

They probably would. But our silicone utensils, if not exposed to high
heat, baking, hold up with out getting sticky.


Either way, our experience with the silicone after being baked was not a
pleasant one compared to the metal equivalents.

But, but, but, I have had silicone stuff break down into a gooey mess
when they haven't been exposed to high heat or oil. It may take years
but it's happened, and far more than once.

I was told, by a chemical engineer some time back, that what's
happening is that plastics have what is called a "plasticizer" (what
else?) that's used to make plastics softer (or harder). These
plasticizers are somewhat volatile and when they leave, what's left
breaks down into goo.

Yes! I have a small space heater in my garage. It's knobs are coated
with a silicone type material that has gone to goo in less than 5 years.

As I noted a while back, the rubbery overmold of things like power
tools and computer mouses is made of the stuff. The more expensive
(good power tools) has a longer life (more expensive) than the cheap
($5 mouse) but they're all destined to return to their primordial goo.

I don't think that silicone rubber needs or has plasticisers.

The knobs may not be silicone rubber. It may be depolymerizing. With
urethane rubbers, this is called "reversion".

One can tell by burning a sliver of the rubber. If silicone, the char
will be sand, not carbon.

Whether rubber or /rubber, goo *is* goo.

If you think it will all return to its primordial glue you've never

OK, so what's different between these two situations? One obvious
difference is the use of oil and other food stuffs when baking but
not when gluing.

Sooo the really big difference is the high heat that the baking dishes
are exposed to.


It could be possible, that based on the articles I quoted, the muffin
tins only felt clean when put away but the unfelt residue eventually
changed it's chemical structure (polymerized, perhaps?) and turned
sticky.

What ever is going on, the silicone baking pans, heat breaking down the
silicone or residue from baking not actually coming off in the
dishwasher but still feel clean we choose to not risk the possibilities
of what was going on.



I've had cast iron skillets turn sticky if not used frequently enough.
Granted, they are put away with a slight coat of oil on them, but it
could be possible that the silicon muffin tins also had a very slight
amount of residue, even if cleaned as thoroughly as possible before
being stored.

Possibly but then they fail because they do not come clean and the
silicone breaks down.



The way to test that would be to put the brushes - or at least the bristles -
through the same cooking and cleaning process and see if they eventually
get sticky.

They probably would. But our silicone utensils, if not exposed to high
heat, baking, hold up with out getting sticky.


Either way, our experience with the silicone after being baked was not a
pleasant one compared to the metal equivalents.

But, but, but, I have had silicone stuff break down into a gooey mess
when they haven't been exposed to high heat or oil. It may take years
but it's happened, and far more than once.

I was told, by a chemical engineer some time back, that what's
happening is that plastics have what is called a "plasticizer" (what
else?) that's used to make plastics softer (or harder). These
plasticizers are somewhat volatile and when they leave, what's left
breaks down into goo.

Yes! I have a small space heater in my garage. It's knobs are coated
with a silicone type material that has gone to goo in less than 5 years.

As I noted a while back, the rubbery overmold of things like power
tools and computer mouses is made of the stuff. The more expensive
(good power tools) has a longer life (more expensive) than the cheap
($5 mouse) but they're all destined to return to their primordial goo.

That will be some kind of urethane rubber for sure.

If you think it will all return to its primordial glue you've never
tried to grind 10 or 15 year old 8B6 off of a propeller blade. The
stuff just gets harder and tougher. Really depends on the
formulation.

I had to look the stuff up:

.https://avioparts.com/coatings/top-coats/8b6-50c3a-1-25qt-akzo-nobel

For sure. Avionics grade.


The stuff I was talking about is the co-molded rubber used in consumer
products.

And again it depends on the product. I like Ecco shoes--I guess my
feet are shaped like their lasts or something. Anyway, they have
polyurethane soles. For a while those soles were good for a couple of
years then rotted away. They've fixed that, presumably by making
adjustments to the chemistry, and my current ones are 6 years old with
no sign of rot.

Might work pretty good for plumbing flux too. Disposable brushes are nice,
but it just feels like such a waste when you're only doing two joints.

I'll have to look for those. How much does the silicone flex?

Puckdropper

Quite a bit. They have approximately 30 little fingers that are about
3/4" long.

Silicone is the latest rage in cookware. I have a couple of brushes like
yours for basting, buttering, etc. We also have some spatulas, stirring
spoons, etc. We haven't tried any of the muffin tins or cake/loaf pans, but
I keep thinking about it. I see them used on the cooking competition
shows all the time. The food items just pop right out, like a ice from
a plastic ice cube tray.
Well for baking silicone has been around for quite a while, at least
10~15 years. I bought my wife silicone muffin tins, bread pans. She
pretty much hates them. So they tend to break down and become sticky
over a period of time. What ever is oozing out is oozing out in high
temperatures into your food.


Are you talking about 15 YO muffin tins or modern day muffin tins?
Well since she had the bad luck she has not bought any more hoping that
it got better.


Compounds have probably improved.

Maybe but they are still silicone unlike the examples you mentioned below.


On the other hand, it's possible that one might confuse a sticky residue from the
food with the breakdown of the silicone. Like I said, I've not tried any silicone
bakeware, so this may not be what you and the missus have experienced. I can
say that I have experienced sticky residue on metal cookware over time.
No, the silicone bakeware was put up clean and developed this
deteriorating sticky goo sitting in the dark of the cabinet.
Trying to clean that goo off damaged the surface.

I was gluing on some edging last night and got to thinking about the
silicon brushes vs. silicon muffin tins.

I'm just tossing this out, not trying to prove my point. It's just a possibility.

I bought an expensive ($150) pair of walking shoes at the beginning of
December. The soles are already just about shot. Apparently, walking
1000 miles isn't good for walking shoes. Who woulda known.

BTW, I have and have had many pairs of the same model in different
colors (it's all I wear - odd shaped feet) and none have worn this
quickly. They've lasted a year or more, though since Covid I walk
outside more. I was on either carpet (at work) or a treadmill (gym).

I do not walk 4K miles per year but do walk quite a bit. I recently
went from Timberland to Keen shoes.. In particular a Hiking boot
design. Water proof, tough. I switched to Keen Targee about a year
ago. I wear them almost every day and the soles show little to no wear.
Same for the uppers. They have developed a squeak but other than that
they may wear for many more years.

stuff just gets harder and tougher. Really depends on the
formulation.

I had to look the stuff up:

.https://avioparts.com/coatings/top-coats/8b6-50c3a-1-25qt-akzo-nobel

For sure. Avionics grade.


The stuff I was talking about is the co-molded rubber used in consumer
products.

And again it depends on the product. I like Ecco shoes--I guess my
feet are shaped like their lasts or something. Anyway, they have
polyurethane soles. For a while those soles were good for a couple of
years then rotted away. They've fixed that, presumably by making
adjustments to the chemistry, and my current ones are 6 years old with
no sign of rot.

I bought an expensive ($150) pair of walking shoes at the beginning of
December. The soles are already just about shot. Apparently, walking
1000 miles isn't good for walking shoes. Who woulda known.

BTW, I have and have had many pairs of the same model in different
colors (it's all I wear - odd shaped feet) and none have worn this
quickly. They've lasted a year or more, though since Covid I walk
outside more. I was on either carpet (at work) or a treadmill (gym).

I do not walk 4K miles per year but do walk quite a bit. I recently
went from Timberland to Keen shoes.. In particular a Hiking boot
design. Water proof, tough. I switched to Keen Targee about a year
ago. I wear them almost every day and the soles show little to no wear.
Same for the uppers. They have developed a squeak but other than that
they may wear for many more years.

It's Merrel boots for me. I have a pair of Moab mid boots and Moab low boots.

https://www.merrell.com/US/en/moab-2...026499366.html

Waterproof, ridiculously comfortable, great support, Vibram sole.

The tread pattern is designed to release dirt and mud so they retain their
traction even on wet surfaces. I can walk all day in either pair, city sidewalks
or woody trails. More comfortable than any sneakers I own.

Neither model offered squeak as an option. ;-)

I feel your pain. 6E. Wow. Mine's 4E, at least in New Balance, and I had
to turn to Amazon to get shoes that fit.

New Balance has been selling their 4E shoes in stores recently. I was
amazed--surprised--and delighted to actually bring home a pair of shoes
that fit from a store!

With all the free return policies these days, buying shoes on line is no
longer a risk, unless...

I needed new water shoes, so I ordered 2 different sizes, knowing that I could
return whichever pair didnt fit. The larger size fit fine and as I was modeling the
water shoes for SWMBO, she said €œThose are nice. Let me try on the smaller size.€�
They fit her perfectly, so she kept them, my treat.

From now on Im not showing her what I bought until Ive already shipped the extra

I used to use the flux brushed for glue but switched to the silicone
glue brushes that Wood Craft sells. Yellow tip, Black handle.

I bought 2 and have been using the first one for 10 plus years. And
Yes I saw the second one yesterday. LOL

Easy to remove the glue if you for get to wash it out.


Might work pretty good for plumbing flux too. Disposable brushes are nice,
but it just feels like such a waste when you're only doing two joints.

I'll have to look for those. How much does the silicone flex?

Puckdropper

Quite a bit. They have approximately 30 little fingers that are about
3/4" long.

https://www.woodcraft.com/products/s...e-glue-brush-1

Silicone is the latest rage in cookware. I have a couple of brushes like
yours for basting, buttering, etc. We also have some spatulas, stirring
spoons, etc. We haven't tried any of the muffin tins or cake/loaf pans, but
I keep thinking about it. I see them used on the cooking competition
shows all the time. The food items just pop right out, like a ice from
a plastic ice cube tray.
Well for baking silicone has been around for quite a while, at least
10~15 years. I bought my wife silicone muffin tins, bread pans. She
pretty much hates them. So they tend to break down and become sticky
over a period of time. What ever is oozing out is oozing out in high
temperatures into your food.


Are you talking about 15 YO muffin tins or modern day muffin tins?
Well since she had the bad luck she has not bought any more hoping that
it got better.


Compounds have probably improved.

Maybe but they are still silicone unlike the examples you mentioned below.


On the other hand, it's possible that one might confuse a sticky residue from the
food with the breakdown of the silicone. Like I said, I've not tried any silicone
bakeware, so this may not be what you and the missus have experienced. I can
say that I have experienced sticky residue on metal cookware over time.
No, the silicone bakeware was put up clean and developed this
deteriorating sticky goo sitting in the dark of the cabinet.
Trying to clean that goo off damaged the surface.

I was gluing on some edging last night and got to thinking about the
silicon brushes vs. silicon muffin tins.

I'm just tossing this out, not trying to prove my point. It's just a possibility.

In this response you said:

" the silicone bakeware was put up clean and developed this
deteriorating sticky goo sitting in the dark of the cabinet."

In another response, you said:

"Ambient room temperature being the relative constant and the
silicone breaks down on its own. Oddly, the silicone brush and
small silicone container have not exhibited this condition."

OK, so what's different between these two situations? One obvious
difference is the use of oil and other food stuffs when baking but
not when gluing.

Sooo the really big difference is the high heat that the baking dishes
are exposed to.


It could be possible, that based on the articles I quoted, the muffin
tins only felt clean when put away but the unfelt residue eventually
changed it's chemical structure (polymerized, perhaps?) and turned
sticky.

What ever is going on, the silicone baking pans, heat breaking down the
silicone or residue from baking not actually coming off in the
dishwasher but still feel clean we choose to not risk the possibilities
of what was going on.



I've had cast iron skillets turn sticky if not used frequently enough.
Granted, they are put away with a slight coat of oil on them, but it
could be possible that the silicon muffin tins also had a very slight
amount of residue, even if cleaned as thoroughly as possible before
being stored.

Possibly but then they fail because they do not come clean and the
silicone breaks down.



The way to test that would be to put the brushes - or at least the bristles -
through the same cooking and cleaning process and see if they eventually
get sticky.

They probably would. But our silicone utensils, if not exposed to high
heat, baking, hold up with out getting sticky.


Either way, our experience with the silicone after being baked was not a
pleasant one compared to the metal equivalents.

But, but, but, I have had silicone stuff break down into a gooey mess
when they haven't been exposed to high heat or oil. It may take years
but it's happened, and far more than once.

I was told, by a chemical engineer some time back, that what's
happening is that plastics have what is called a "plasticizer" (what
else?) that's used to make plastics softer (or harder). These
plasticizers are somewhat volatile and when they leave, what's left
breaks down into goo.

Yes! I have a small space heater in my garage. It's knobs are coated
with a silicone type material that has gone to goo in less than 5 years.

As I noted a while back, the rubbery overmold of things like power
tools and computer mouses is made of the stuff. The more expensive
(good power tools) has a longer life (more expensive) than the cheap
($5 mouse) but they're all destined to return to their primordial goo.

That will be some kind of urethane rubber for sure.

If you think it will all return to its primordial glue you've never
tried to grind 10 or 15 year old 8B6 off of a propeller blade. The
stuff just gets harder and tougher. Really depends on the
formulation.

IIRC I returned a pair that were to narrow, a different style, returns

Yes, these are New Balance (928's). The only place to get New Balance
4E is in _their_ store and the wide (wide) shoes are only available in
a few models. A few is better than none, anyway. The 6E widths aren't
available in their stores at all. They can order them but so can I. I
They don't have a store on this side of the city and I rarely venture
to the other side. There is a Woodcraft on this side. ;-)

Actually, my feet aren't all that wide and I can't convince the droids
in shoe stores that I need the wide shoes. They measure and say
"nope, here is a nice pair of 'D'". OK, get them on my feet. Hmm.
My feet aren't real wide but I have very high insteps. To get shoes
that have enough material to get to the top of the foot, wide sizes
are needed. There is no way I can wear loafers or bedroom slippers,
in any size.
