I don't know. Try it and let us know what happens.

silver wire can be fused but it must be .999 fine, NOT sterling. Copper wire works but you need a long anneal in my experience. nichrome will stick but i have found it to cause cracking when used as exterior hooks or loops. In leaf or fine dust/frit form, most metals will adapt when used in small amounts.mica is also a cool effect. m

I made some paperweight bottles with steel wool embedded in them. Apparently the small diameter makes it more forgiving because there has been no cracking. However, it wasn't very attractive either....

Ever think of trying it with bronze wool? I have no idea what it would turn, but no doubt it would change color, and it is copper base metal.

No. I never heard of bronze wool. I'll have to find some and try it. The steel wool burns spectacularly when it goes into the furnace, but some remains on the surface. Not that that has anything to do with the results, but it's Kinda Fun.

Thanks for the suggestion.
