Ooooh Sanippy those are beautiful! Did you get the keshi from Cees? I've become slightly obsessed with all forms of SSPs lately, they're so gorgeous.
BWeaves, once metal clay is fired it's metal, so it has the same properties as any other metal. However, generally speaking it's going to be a bit more porous than sheet metal or wire, so soldering it can be tricky. It can be done, it's just fiddly. It can also be a bit more brittle, but honestly if the manufacturer didn't keep messing with their recipe that wouldn't be an issue... Every formulation fires slightly differently so the first few times are a learning experience. But theoretically when you stick with the same type/brand of clay, once you have your firing method sorted out it should be consistent. Hence my irritation at the changes. Oh well. I have a fun idea for repair.
