Has anyone used copper sulfate on beads?
(Accidentally put this on the front door. Reposting)
Hi! I've just started beadmaking with a Firework touch. I'm really enjoying it. From playing with etching I have copper sulfate and was wondering whether it would react with the glass. I'm not a chemist, I'm not recommending this.
I've done a little experimenting (grinding it to a powder, rolling bead on it) and it's interesting and capricious. On ivory I get black curdling. Sometimes black curdling on orange and yellow. With white I get subtle light blues and pink.
Again, I'm not recommending this. I'm mostly concerned about the sulfur -> sulfur dioxide -> air born sulfuric acid.
I tried searching but couldn't find anything.
Thanks in advance!

I haven't tried it, but from experiments with other chemical/mineral compounds, I hope you have an excellent ventilation system. Some of the most innocent sounding things turn nasty when they get volatilized by heat. Be careful.
(I tried fuming glass with EDP until I found out that those pretty colors were lead volatilizing out of the glass. Um, no, didn't do it again.)

Thanks for the reply. Sadly, my ventilation isn't good enough right now to do any more experimentation. Someday

Creating sulpher dioxide is a really BAAAADDD idea.
If you want to play with copper effects, copper leaf is inexpensive and will gove you the results you want.
Try it with opal yellow and white base glasses, lay on the leaf and really cook it in until you see the pretty blues and greens appearing.
Search on here for copper leaf to see some ideas and uses.

I agree about sulfur dioxide (eek). Next order I'll try to remember to get copper foil. Thanks!

You can buy the copper leaf at Michael's. It is the Mona Lisa brand. Works just fine. Really, really, really cook the stuff into the bead, and use just enough for one roll on the bead - don't overlap!

Copper sulfate is poisonous if swallowed. Most water soluble heavy metal compounds are toxic, even those that are essential nutrients in small doses.

I have used this on beads. It makes a lovely blue/green colour

As a fiber dyer, I would steer clear of copper sulphate, period. I do use it with dyeing, but only with extreme care...heavy gloves, a respirator and outdoor 'cooking.' It's an excellent mordant but I only use it rarely...run a big batch of fiber, and then leave the pot outside so the water evaporates, and mix the last inch with kitty litter for disposal. And THAT's only using it dissolved in water. I don't know chemistry that well, but basically setting it on fire strikes me as very, very bad.

Thank you all for the replies. I went to AC Moore, found copper leaf, it was expensive, I had a coupon and it was not. Tried it with yellow because I'm out of ivory. The bead is mostly metallic dark gray and terra cotta from the copper. No interesting patterns. Maybe I didn't cook it enough? I might have accidentally over wrapped too.

Yep keep cooking that bead.
Wrap only once
Use OPAL yellow or white. Regular yellow may react in ways I don't know.
If you are getting metallic copper then you need to turn your propane down (or turn the torch down if you are on a hot head)

I've always been told to roll the bead in white enamel before applying the copper leaf, then cook.
I guess the enamel isn't absolutely necessary, since not everyone uses it, but I think it makes it easier to get the blue color.
I've never had that much luck with using copper leaf, though, so YMMV.

I've tried the copper leaf a couple times this week and man, I'm just not getting good results. Is silver leaf easier than copper? Maybe I should practice with that first.
Ordered an assortment of rods, only one ivory. Think I need to do another order soon to continue sperimenting.
Trying to ... resist temptation... to play with... copper sulfate...
On a slightly safer side, I tried embedding industrial black diamond into a bead. I think it has potential if it doesn't misbehave in the kiln (pieces that weren't fully embedded were sharp to the touch and cracked the glass).

Oh yes, silver leaf looks wonderful on many colors. No cooking required!

BTW, there were lots of discussions about using copper leaf way back in the day on wetcanvas.com . Here is one that has lots of good info:
http://www.wetcanvas.com/forums/showthread.php?t=179688
Here's another good thread that talks a lot about using enamel with copper leaf:
http://www.wetcanvas.com/forums/showthread.php?t=102337
I hope it's ok to link to WC! I stopped going there in 2005 when I found LE, but there is still some good information there in the old threads.
