Fusing is fun! OK, sometimes frustrating, too, but also fun. It's so magical!
And no- sterling doesn't fuse, because the copper in it oxidizes too readily. That's why granulation on sterling is a lot trickier than on fine. (There's a trick that can make it work, but not as reliably as it does on fine.)
Both of my loop-in-loop chainmaking books have some info on fusing- the classic one, and the new Lansford one. The Lansford one
has better photos but no diagrams; the Stark one
has minimal photos, lots of usually-helpful drawings, and a LOT more types of chain. Both are kinda pricey, unfortunately. I think the Stark is a better value in general, but the Lansford definitely has more on fusing.
What are you interested in fusing? The techniques etc. vary a lot depending on whether you want to do loops like for chain (as above), or granulation/wire fusing onto a flat sheet, or bezels, or whatever. I'd be happy to post some about any of these if you're interested!
Oh- and there's one exception to the "can't fuse sterling" rule: take scrap with no solder, flux well, and fuse bits to each other or to a backing sheet by just heating the heck out of them until they melt to each other. This is very unpredictable/"organic" in results! but it can make a nifty on-off THING, and is a fun way to use sterling scrap. :)
