Arthur, as I´m currently after a plate for small core stars, I can tell you that Wolter offers them, at least down to 3mm in diameter. I asked for a custom made 2mm plate, we´ll see what he can do. Not quite cheap though.

I don´t know how these are made. Sorry.

Check your mail, digger. Thanks!

Thanks. I´m not searching for the lab grade though. The tech. quality I want comes in 50kg barrels.

Just out of curiosity, what exactly is it that you believe Arsenic will do that other elements won't? What specific chemical reactions occur with arsenic in a flame envelope?

A technician in contrast to a scientist is a believer. His or other´s "experience" will tell him that paris green in chlorate compositions is able to produce blues as good or better than the finest AP colors, showing large flame size, easy ignition, less compatibility issues, lower prize, high wind resistance etc. The reasons will remain unclear though. I´m a technician, so I can only cite others and refer to hypothesis saying that the arsenic mediates the chlorine transfer to the copper. At least, it DOES have properties other copper salts don´t have, as PG blues are simply not reproducible with more modern compounds such as the oxide, oxychloride, carbonate or benzoate.

The way you were asking - though - made me assume that you are either sceptical about the latter statement or already know the answer to your question.
