...It doesn't stay red!
At the beginning of the month, I introduced January's birthstone - garnet. Since Valentine's Day is coming up, I thought I'd continue with the red theme, but this time talk about the red glass itself.
First off, all the pinks and red glass I use is artists's stained glass, as the few apparently red glass bottles you may have seen are all actually painted - and sadly, the paint just burns off.
Red glass is surprisingly difficult to work with. Because I melt glass using focused sunshine, the intensity of the heat is highly variable - and so is how the heat is distributed through the glass. With darker colors (like the garnet red glass above), much of the light (and thus heat) is absorbed on the side facing the light, while the other side remains cooler. I have to flip and turn the glass constantly to heat the drop evenly enough to form a symmetric handmade glass drop. But the red glass still doesn't heat perfectly evenly, as it would be in a kiln.
