I've gotten good advice here in the past. Maybe someone can help me with
this problem

I have a rather expensive oven mercury thermometer. When using it in a
combination MW/convection oven with a rotating surface to test the oven
temperature, evidently the vibration caused the mercury to be widely
scattered thoughout the glass column. I read a site info on this problem
but none of their suggestions helped. Tapping it into my hand to move the
mecury, heating it, etc.

The only other idea I have is to somehow fasten it to an electric drill and
spin it so the centrifugal force forces the mercury to the bulb but can't
figure out how to securely mount it.

Any better ideas?

TIA

Does your oven vibrate like a paint mixer? I've
never seen any vibration on a rotating base inside a microwave that
had any significant vibration. They turn
at like 3 RPM. I don't see how that could account for
mercury seperation in a thermometer.

Maybe I'm wrong, but I thought these ovens allowed you
to use both at the same time. Some I though just used
MW for heating combined with a fan for convection, Others
I thought added other conventional heating elements
together with the convection.

You will probably have to do this repeatedly, shaking first toward one end, then the other,
but eventually you'll get all of those different blobs of mercury back together.

There's supposed to be a vacuum in the tube.
If you heat it gently, you should be able to make the blobs
run together. If that happens before the end of the glass,
you're good to go. But the difference between FIXED and BUSTED GLASS
can be very small...depending on how far the last blob is from the top.
Did I mention GENTLY.

I can't imagine that an electric drill is a good idea.

What Doug said.

You can put the thermometer in a sock and swing it around to increase
the force.

Or instead of tapping on your hand, you could tap it on the desk.
It's been decades since I had a thermometer with separated mercury,
but I think that' what I did, and I was able to do it without breaking
the therm. Of course my desk might be softer than your desk, or my
arm weaker.

Tie a small strong cord around the top end of the thermometer using a prussic
knot after winding a rubberband around the glass to add friction. Then go
outside on a big area of grass, pull the knot tight, and spin it as fast as you
can.

Ken,

All of the centrifugal force techniques are good to try. If they don't
work put the thermometer in the freezer to cool. Keep it upright (mostly).
Now make a cold bath with rubbing alcohol and dry ice. Put the thermometer
bulb half way into the bath. The mercury should shrink down into the bulb.
If any mercury is left in the column use the centrifugal method again. Wear
gloves. After the mercury is in the bulb remove the thermometer from the
bath and hold it upright until it warms up.

I once owned a beautiful mercury lab thermometer that was some 18" long.
I opened my desk drawer one day and slipped the long thermometer
out of its cardboard tube only to find the bulb broken. There was some
soot on the remnants of the bulb that looked as though someone had held
a lit match to it. No one in the shop would admit to touching it since
they didn't wish to acquire any fatal injuries. o_O

TDD

I've heard of super cooling, so all the mercury ends up in the bubble at the
low temp end. Not sure I've tried this, but sounds good.

You might try attaching a very strong cord to the end opposite the bulb
and going outdoors, find a large open space and spin it around like you
were spinning one of those noisemakers. A 24" cord should be long enough
and the centrifugal force from spinning should move the mercury back
into the bulb. ^_^

You were tempting the gods of fate if you put a mercury thermometer
into an operational microwave oven., The mercury would heat up almost
instantaneously and shatter the glass into smithereens, contaminationg
the oven probably beyond repair. I have never heard of anyone using a
mercury thermometer to cook, That would be like using a stopwatch to
bake a cake, etc.

To reinstate the column, you need to heat it so it reads maximum/
mercury goes to the top of the tube.
If you examine the tube, at the end opposite the bulb there is
usually another void to prevent the bulb from bursting when this state
is reached.
Do NOT overheat.
If there is no void, do not let the column expand to the end of the
tube while you are doing this.
And wear eye protection.

The reason the mercury column has broken is that it is unsuitable for
a microwave, the metal has boiled so making the gaps.

You didn't know? I put up an outdoor mercury
thermometer. Microwave ovens stopped working
for about a six block radius. It just sucked the
microwaves right up. It was fun, watching all the

No, but the drill idea sounds like a very bad one. *Unless you
want broken glass and mercury contamination all over the place

That's why I said 'securely'.

I have a rather expensive oven mercury thermometer. When using it in a

temperature, evidently the vibration caused the mercury to be widely
scattered thoughout the glass column. I read a site info on this problem
but none of their suggestions helped. Tapping it into my hand to move the
mecury, heating it, etc.

The only other idea I have is to somehow fasten it to an electric drill and
spin it so the centrifugal force forces the mercury to the bulb but can't
figure out how to securely mount it.

Any better ideas?

BTDT but only twice and it was for a relatively low temp thermometer
so I think I used boiling water?

Simple solution.. BTDT but only twice.

Mercury thermometers typically have tiny expanded volume at the very
upper reaches of the mercury column.

Slowly heat the thermometer until the mercury expands into that space.
Be careful.... as the thermometer heats the little segments will move
towards the top volume.

Wear safety goggles and check the thermometer often.
As long as the column is segmented, the risk breakage is small.
When the column "goes solid", that's when breakage occurs.

If you heat very slowly & check often...you'll be fine.

NEVER put a mercury thermometer in a microwave. The mercury attracts
the microwaves and super-heats. Or did you have your "combination"
oven in non-microwave mode???


Yes. It has three modes - mw only, oven only and both. I was in oven only
mode.

When using it in a
combination MW/convection oven with a rotating surface - in MOST the
rotating table only works in MW mode. - al teast the ones I've seen.

In mine it turns in all modes.

Or are you asking where anyone suggests it was in non-microwave mode?
Because nowhere does it suggest that he did THAT either.

It was in oven-only mode using a heating element, not the magnatron.

You were tempting the gods of fate if you put a mercury thermometer
into an operational microwave oven.,

It was in oven-only mode, using a heating elenent instead of the
magnetron.

The mercury would heat up almost
instantaneously and shatter the glass into smithereens, contaminationg
the oven probably beyond repair. I have never heard of anyone using a
mercury thermometer to cook,

I was using it to test the temperature; the oven is currently not heating
correctly - says it has preheated to say 400 but is actually only at 300
and goes no higher - while the repairman was present.

That would be like using a stopwatch to
bake a cake, etc.

To reinstate the column, you need to heat it so it reads maximum/
mercury goes to the top of the tube.
If you examine the tube, at the end opposite the bulb there is
usually another void to prevent the bulb from bursting when this state
is reached.
Do NOT overheat.
If there is no void, do not let the column expand to the end of the
tube while you are doing this.
And wear eye protection.

The reason the mercury column has broken is that it is unsuitable for
a microwave, the metal has boiled so making the gaps.

The magnatron was not in use - the oven-only mode uses a heating element
only.

"Attracts microwaves", now there's a concept! A new physics is
invented every day, on the Usenet.


OK -maybee the description is not totally accurate, but the result is
the same. Mercury behaves differently from most other metals - it is
diamagnetic (or antimagnetic) - and magnets DO attract microwave
energy, while most metals reflect it.

This is an answer to the question "should you use a mercury
thermometer in a microwave oven?"

On the other hand, putting a mercury thermometer in a microwave oven
isn't a good idea. While mercury is a metal and will reflect most of
the microwaves that strike it, the microwaves will push a great many
electric charges up and down the narrow column of mercury. This
current flow will cause heating of the mercury because the column is
too thin to tolerate the substantial current without becoming warm.
The mercury can easily overheat, turn to gas, and explode the
thermometer. (A reader of this web site reported having blown up a
mercury thermometer just this way as a child.) Moreover, as charges
slosh up and down the mercury column, they will periodically
accumulate at the upper end. Since there is only a thin vapor of
mercury gas above this upper surface, the accumulated charges will
probably ionize this vapor and create a luminous mercury discharge.
The thermometer would then turn into a mercury lamp, emitting
ultraviolet light. I used microwave-powered mercury lamps similar to
this in my thesis research fifteen years ago and they work very
nicely.

Well, there you are. If you don't use the magnetron it will take
forever for your slow-cooker to make toast.

Also, it is obvious that your mercury thermometer needs lubrication.
Can you give it a little shot of WD-40?

And then stick it up...?

I would agree. I'm never going to use mercury, and I don't think I have
one. I do remember lab oven/incubators with mercury thermometer sticking
out the top. I used to compare readings with various thermometers, but once
I verified, I put the mercury away.

I forgot my combo had a combo button. The heating element will preheat the
oven, and then cycle between microwave and heat, but never both at the same
time. My platter rotates in either mode. The tray is usually inserted over
the platter, and platter not really used, but I would have to reread
instructions for turbo oven mode and microwave.

I never turbo cooked anything in that oven, because it's slow compared to
my little turbo oven which includes radiant heat.

I use a grilling meat thermometer I bought at kmart for $12 on sale.
Digital with probe and stainless cable. I just have to subtract about 10
degree error.

How metals react depends on length. If about 4 inches long will resonate
and maximum current will occur in center. Other lengths will still develop
nodes of current. No mercury please.
