I was trying to see if I can do some more handcoating for paper , anybody happen to know where I can get RAW Chemical for doing this, say in smaller amount similar to educational / hobby use.

I do not mean checmical for photofinishing, but real RAW checmical so I can mix my own formula ( something like Sulphamic acid, Silver oxide, etc ... )

Why you need sulphamic acid? I know you need to buy at 25kg a pack. Can you share with us your formula so I can understand more what you are going to do?

You can try to contact this and they sell analytical grade chemicals:

Well, thanks. Actually I am not specific about chemicals, but for real I am now trying to do my own alternative processing mostly prints, and to do that mean I have to mix up my own chemical and coat my own paper ( or media )

Still the one process now I am experimenting is going to be less demanding on materials although its very time consuming !!!

Well, have not got the time to talk it over with that company but the web site is not that great. Still, I need more time and experiment. Well, I am not inventing my own paper emulsion. There are numerous historical formula around, that just need adaptation and need working experiments.

The problem with many of todays photographer is their set mind. Color had to be C-41 or E-6, B&W is all about just the Silver type, but for real there's too many other photo process / printing process that can just be so great for image making.

Right now I am trying out blue print and POP !
