Pure aluminum melts at 660C, alloys have lower melting points.

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 fine .

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
termperatures:
