Using ( pretty successfully I must say ) HG Mould Remover around my
bath I saw that the brown residue that is left can be removed using
Sodium Thiosulphate but have no idea where it can be obtained or if it
is known as anything else . Anyone know ?

Just realised it is aka Hypo which is photographic Fixer .
I have found it here
http://www.mistralni.co.uk/details.p...YA4wode3mEI A
but no doubt there are cheaper sources .

Time was you could buy it at any photographic shop.

Thx for that ..Dunno what the "5 Water LR" means though .

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Bruce

I'm not an expert but I think it means that it's the pentahydrated
(crystalline) form rather than the anhydrous (powder) form; i.e. it
contains water of crystallisation. I can't see that it matters in your
application although it might if you were assaying silver content by weight.

If you're really bothered try:

"5 water" means 5 water of crystallisation aka pentahydrate

see: http://en.wikipedia.org/wiki/Sodium_thiosulphate

and http://en.wikipedia.org/wiki/Water_of_crystallisation

Anhydrous means "without water of crystallisation"

so 500g of anhydrous gives "more" hypo than 500g of pentahydrate,
because part of the amount you buy includes the weight of any water of
crystallisation.

LR means "Laboratory Reagent". Basically, you can buy chemicals in a
number of different grades.

"Crude" - with significant impurities. E.g Rock salt for putting on the
roads.

"Technical Grade" - pure enough for straightforward
industrial/commercial processes. May be contaminated with
inert/un-reactive substances. E.g. Swimming pool chemicals.

"Laboratory Grade" or "Laboratory Reagent" - containing very limited
amounts of impurities and sometimes guaranteed free of particularly
undesirable impurities (for some value of undesirable, which varies
according to context).

"Food grade" - suitable for human/animal consumption.

"Medical Grade" - which will have "BP" or "BPC" after. E.g. Sodium
Chloride B.P. This means that it has been manufactured/prepared and
tested/quality assured in accordance with the British Pharmacopoeia or
the British Pharmaceutical Codex.

"Analytical grade" or "analytical reagent" - extremely pure, for
chemical analysis and/or where any amount of insoluble impurity might
clog up the works of a sensitive scientific instrument.

Aah! Thanks for that ..Makes it totally clear ..If the use of this +
the previous use of HG Mould Remover works then that will be of use
to a few folk in here as the subject seems to come up regularly .

Always had a test tube of that in Chemistry sets as a kid ... now I know
what it was for ?

I suppose Chemistry sets would never get past 'effin Safety nowadays ...


My mother recently passed on to me another toy form my youth ... a Mamod
Steam Engine .....
It still works after not having not been fired up for more than 30 years !

'effin Safety would probably throw an eppy over selling meths burners and
steam vessels to kids :-)

If you hunt around on google, reasonably "proper" ones are still available -
as in similar to the ones kicking about in the 70's (mag ribbom, metsh
bunsen, copper II sulphate and an array of other bits and pieces...

On an aside, can you still get carbon tetrachloride? Wasn't on that site

Carbon Tet was the main constituent of stuff for taking stains out of
clothes was it not? no doubt been banned long tme ago.

Carbon tetrachloride is an ozone depleting substance and also a
greenhouse gas. It hasn't been banned, but its use has been strictly
limited by several pieces of EU and UK legislation.

It was used in industrial quantities in the manufacture of
ozone-depleting refrigerants R-11 and R-12 which have now themselves
been banned.

A lot of stuff that will raise eyebrows[1] in the local chemist shop is
actually freely and legally available on the internet.

eg http://www.gardencentre.co.uk/produc...=gbase&ad=7865
(Have to sign for that in the chemist's)

Mag ribbon http://www.lpchemicals.com/product.php?Id=317
(always on ebay)

etc...

Once I even found a place that claimed to sell metallic sodium - but it was
in whole bars and cost a fortune.

Also, be aware that is an online chemical supplier seems to have a strong
bias towards selling highly reactive substances and none of the "boring"
chemicals, it's probably a sting website. Even if it's not (perhaps it's a
pyro supplies place) then be sure various agents of the state will probably
be either keeping an eye on it or are liable to go and legally grab a
customer/orders list from time to time. So no buying 50kg of bomb making
chemicals.
