    Looks like lots of good stuff on that website, not just a foundry. That guy seems like he would fit in well around here.

    so for something completly different
    i recently started making these small aluminium electric foundrys and selling them on ebay.and then someone asked me if it would melt brass ,well it sure gets hot enough. so i decided to give it a whirl. well when the brass gets hot enough it starts a weird fire and makes this powdery residue. can any body out there tell me why the brass does that, and how does one melt brass

    If I remember, Brass contains zinc and it is very bad for you. 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.

    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.
    Have a good one.

    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

    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
