You may have heard of the t.v. show “What Not to Wear.” Well I’m seriously considering a blog series called “What Not to Do.” In the kiln, that is.
Here are some pictures of what happens when you, or more correctly I, try to put too many wine bottles in the kiln. I usually put 4 bottles in my Paragon Pearl 22 kiln. But yesterday I thought, “heck let me put in 5 – 4 in one direction and a fifth one the other direction.” Not a good idea! As you can see in the picture, four of the bottles fused together. I have accidentally fused 2 together before, but never all 4!
Now while this looks like it would make a very interesting serving tray, I have no way of knowing if the glass used in the different wine bottles are compatible. Two pieces of glass that are fused together must be compatible which means they must have the same COE (coefficient of expansion). The glass I use for fusing is all compatibility tested with a COE of 96. If the glass is not compatible there could be stress introduced in the glass and the glass could break at any time. I have read that the glass be okay for years and then one day just break. I am not expert in this matter, but I’m not taking any chances with it.
