I do things on a small scale. When I buy glass, I do it 1/4 lb. at a time, both for financial reasons because I have to have all the colors at once and because, well, I have to have all the colors at once and Joe is starting to say things like, "You got more crack," when a package comes. More on that another day. I buy MAPP gas in 1 lb. cylinders because my apartment complex prohibits 20lb. tanks for grills and I don't think they will wink at my glass. When a bead goes bad a little piece of me dies. OK, that's a little extreme, but I definitely analyze the heck out of it and try not to make it happen again. I have been experimenting a lot, like any beginner will, and I have my share of strange beads, but I hate it when I can't use them. On these, they just turned out to be unworkable. The top 2 had separator issues and the bottom one, well, I don't know what stuck to my utility blade tool but it looked too bloody to use.
Note to self: Don't sit there waiting to see what color something is going to go, just garage it. I am not an expert at encasing, in fact, it could be said I sock at it. In these cases, I didn't sink the beads in anealing bubble fast enough to prevent mild thermal shock. The cracks don't go past the encasement layer, but not because I mixed glasses, I don't think. The flat bead is Effetre dark matter, DH aion2, and clear and the round one Effetre gaillo ocra, aion2 and clear. I can still look at these, but for the functional use they were intended they will not do.
This is one that I did the first month of making beads, back in October. I don't know what I did wrong, or right, since I like the bead and tried to do it again, but the first bead I made using Effetre anice white had a uniform transparent grey layer over the white. I didn't smoke the glass, I think, since it doesn't have that streaky thing going on, nor is it a reaction to the millefiori, since the other beads I made using the same combination didn't go all wierd. Just a neat effect.
This last picture is what happens when you have a fat wad of various shades of green and aren't paying attention to what you are doing. My mind was thinking apple green and my brain didn't register that I had another glass that could be interpreted as apple green color: Effetre cool kiwi. So several beads that should have been CiM poison apple were made with Effetre cool kiwi. The kiwi rod is on top. Note that it has been used. I just have to make more beads tomorrow. What a shame.
