At first I thought, broken glass, but I haven't broken anything recently and I live alone apart from the cat. Further investigation produced all these beautiful crystals.
Sadly they will react with moisture and dissolve again eventually otherwise you can bet I'd find a way to make jewellery from them!
Apparently they will carry an electric charge and there's all sorts of stuff on the net about how to use them, none of the crystals I've seen there are as big or as beautiful, I did add lemon juice to make the solution a tad more acid, maybe that makes the difference?
I shall just admire them for now until they disappear.
I'd appreciate any knowledgeable person giving me some more info about these beauties.
Meanwhile here's some of the work that I've made that needed to be cleaned
This is a bit of an experiment, I bought these copper stars and up to now I've made pendants just using one, I wanted to see if I could make something more complex, there's a bit of an industrial feel with the copper wire, because the silver is applied by melting with a blow torch the results are unpredictable so the earrings are not an exact match. I quite like that, hopefully others will too.
I call this one Planet, it has a sort of Jupitery, Saturny feel to it. There are actually two stripes of silver wire but the top one was thinner and almost melted completely.
These random effects are really lovely in my opinion. This one is domed slightly to give a more substantial feel to the piece. The chain is a recycled silver trace chain, bought from a collectors market with a fairly naff pendant on it which I discarded.
There are two new pieces soaking in the magic cream of tartar solution now, a heart and another disc.
