Working on some new prodo
Here's the pics of the finished piece. It's not as clean as the last one I did, but it'll do for me. Kinda messed up my encalmo section cause I wasn't paying as much attention as I should have been. Didn't really start to focus until I already messed it up. Also used old scrap tube for most of it, and you can see it in the fume. Can tell the tube was still a little dirty due to the "spottiness" of the fume, but I think that looks cool. Adds some more variation to the fume. Not my cleanest bends either. Functions beautifully though. I'm really just being really picky about most of this stuff too, but that's just how I am. Nothing's ever good enough. lol

Made this hollow space pendant out of some scrap last night, but the opal exploded in the kiln overnight. Thought it was pretty cool though up until that. The space tube was a piece of scrap left over from the sherlock up above, and the opal was a big old opal that had a pretty bad crack in it already. I don't like to break polished opals, so I tried to use it with the crack, and was gonna give it to a friend who really liked the opal when he saw it. Also didn't have as much clear around the opal as I should have. The opal was pretty big to start, weighed in at like .4g if I remember correctly, and I didn't want to have a big marble on it either, so I just went ahead and took the risk. Was properly annealed as well. I guess both things combined were just too much stress for it to handle. Oh well, you win some, you lose some. No big deal since it was all scrap stuff, but still a bummer to see it not survive.

i think i heard somewhere that you need approximately 2-3 times as much glass around the opal as the opal is wide. What a bummer though that looked sweet, Do you mind telling what the space color is?

Profound recommends having at least as many millimeters of glass on all sides of the opal, as the opal is thick, I believe, and I think that goes especially for rough opals. I too have done a bunch of opals without that much clear on them and gotten away with it more times than not, but that is recommended because when the glass around the opal (or anything for that matter) is thin, it has a much harder time containing the stress during the annealing process. Polished opals seem to not have much trouble no matter how much glass is around it, as long as the opal is not too large, and small rough are usually ok as well, but this one was around 7mil thick most of the way through, already had a crack in it, right before encasment I dropped it and broke a piece off, which made an unpolished rough side, and had less than a 2 mil of clear on most sides. I believe all of these factors combined simply caused way too much stress for it to handle during annealing.
Edit: Mike, the space color is silver filings and gold fume on cobalt, then tube encased in clear.
I bought a gram of opals and only got 2 out of 5 to survive and they got scuzz all around them and didn't look that great. My first time using them though
Dude. cheesenip, my man.
Nah, nah. See, I meant to do that.
