I’ve cast a lot of silver and bronze, but I’ve never tried casting
stainless steel before. But I’ve got an induction casting machine,
and I’m thinking about trying to cast some. I know it takes some
special investment; what’s recommended and where do I get it? Do I
have to use flux? Are there any special procedures I need to follow,
or can I use the same vacuum-casting techniques I use with silver?
Do I need to melt it under a gas blanket, and if so, what gas should
I use? Are there any particular safety measures I need to take, like
wearing special goggles? Is the amount of hexavalent chromium
released from a jewelry-scale melt something I need to worry about,
and if so is simple ventilation enough to deal with it, or do I need
to wear some kind of breathing apparatus? I’d really appreciate some
input from people who have done this.
