Thanks, I will just do some tests in with some glass firings, I don't quite
understand what the other posts are talking about but as an artist I tend to
just try things out, I just wondered if there were any fumes or gases given off
that could cause problems. I have done some enamelling onto steel and it worked
What they're tlaking about, in our semi-engineering language, is the
fact that aluminum will melt into a puddle at the firing temperatures
you're asking about.
Aluminum can't tolerate those temperatures. If you want to consider
using other metals, here is a list of metals and their melting
Some metals do emit fumes when hot, like lead, zinc and cadmium
(plating), but AFAIK there are no special precautions when welding
aluminum other than avoiding fluoride fumes from the flux on stick
Pure aluminum may be too soft and flexible for you. The commonly
available strong and stiff alloy 6061 begins to melt around 580C.
Aluminum expands and contracts about twice as much as steel with
rec.crafts.metalworking may not be a good source for artistic
metalworking, we are more about machinery and politics. They may have
confused you with a political spammer.
Perhaps Calphalon or another company that bonds ceramics to aluminum
industrially could help with low-melting ceramics and surface
pretreatment requirements. I've never found any useful information on
tricky chemistries from artistic sources.
I'd be cautious with the colors you are using.
Are some arsenic or cadmium or lead or .....
I had a good friend who used to much cobalt blue
and without a mask. Was tough on his lungs...
Glass is safer.
Stainless steel will give off bad fumes.

It does. After so many years, I have kill-filtered over 85% of the
messages nowadays, so on days with 150 or so posts, I see only a dozen
or so. It's sad that the valid content has dropped so much. Filtering
crossposted messages took care of an immense amount of the crap in one
pop. I just wish Agent filtered on initial post ID so I could get rid
of all the posts by those who reply to the jerks I have plonked. I'd
switch newsreaders for that alone if they weren't all such a different
format. Agent is THE format for news. I wish others laid it out like
Forte' does. Online forums are immensely painful in comparison; so
clumsy and inefficient.
I WANT THAT FEATURE, FORTE!
