That guy seems like he would fit in well around here. :D Klox 08-07-2003, 03:48 AM Very interesting!!

It is the same as welding galvanized material, very bad for the lungs. I don't know how to melt it safely. I could be wrong but somebody will step in and correct me if that is so. TinkerDJ 10-21-2008, 11:54 PM You need to use a flux to stop that, its one of the problems with casting alloys. Try a search for flux for metal casting. I've used Borax for casting aluminum, but i don't know if you need something different for brass. Lurkepus 10-23-2008, 06:18 PM i have been working at a factory producing zinkdust for paint we also produced zinc oxyde witch are used in a lot of products and i never had any problems even though i got to inhale smoke from the zinc boilers . i guess the toxic stuff in the fumes are from the welding rods and other stuff they have added to the zinc .. i found a company that can provide you with both FLux and degasse for brass casting http://www.budgetcastingsupply.com/Brass_Flux.php http://www.budgetcastingsupply.com/Brass_Degas.php they also provides other usefull stuff http://www.budgetcastingsupply.com hope this will help you on the way Btw i guess the flame is kind of green and the residue is zinc oxyde witch is jut zinc burning in regular air |
