Default Where can I buy sulphuric acid?

Hi all,

I want to do some anodising, and I am trying to locate a source of
sulphuric acid. Battery acid would probably be the easiest way to get
hold of it, but all the car part places around me say that they aren't
allowed to stock it any more because it is a restricted substance.
Curiously, despite being restricted, I can still buy it mail order and
have it sent to me through the post (http://www.getgeared.co.uk/
acatalog/Battery_Acid_1_Litre.html)!

If I can I want to avoid the postage charge for mail order (the cost
of the acid is less than the P+P) so does anyone know of any other
place that would stock sulphuric acid?



You could try any big builders merchants and look at drain cleaners. Some
are sulphuric acid others sodium hydroxide.

Anodising is fiddly. Unless you really want to d-i-y or you have a lot to
do or an odd colour it may be worth just asking a local anodiser. I had all
the parts for a microscope black anodised by a local works for £10 - less
than it would have cost me to set up and do it myself.
