UK chemical suppliers?

Hi

I am starting out in alt processes using cyanotype and the argyrotype kit from Fotospeed.

I am interested to try salt and and other methods (kallitype and VDB for instance).

Are there any reliable suppliers of the chemistry in the UK?

Thanks.

Unfortunately since the demise of Wetplate supplies, I can't think of any UK supplier that sells ready made kallitype or VDB. A few years ago I started with Kallitype and I think I got pre-mixed solutions from someone in Lithuania via eBay (quick check still available). For VDB, tartaric acid acid and silver nitrate can now be sourced from ebay. At that time, you could buy kits and raw chemicals from Europe but that path is now closed. I settled on argyrotype, have used the Fotospeed kit but like to mix own.
