Remember when you were a kid and your parents said, "Don't touch that it's hot" but you did anyway? Now that you know that valuable if not hard lesson your definitely not gonna reach out and grab hot glass. However, one of the closest ways to touching glass while it's still hot is to use tweezers. Glass tweezers can be found in several shapes and sizes and can be used to manipulate hot glass. Keep in mind though if your tweezers points aren't sharp than you will be fighting an uphill battle. To keep this glass tool working properly periodically use a fine toothed file to keep the points in shape.
So what’s on the menu for today? How about a nice big slice of devitrification. Devitrification is the process where glass becomes partly crystallized as it cools from the molten state. This is usually because it cools to slowly. So you open up your kiln and find that devitrification has occurred on the surface of your fused glass but you know that it wasn’t from cooling to slowly. What now? It may also have happened because you accidentally heated your work to too high of a temperature or because of unsuccessful annealing.
Happy 4th of July! Ok, maybe I am 4 days to late but I've been on vacation. Wow, it has been entirely to long since I've written a glassblowing or fusing tip. Well as they say there's no time like the present.
Today were going to increase your glass vocabulary by giving you a definition. And today’s definition is (drum roll please)……broken-swirl ribbing. What the heck is that? Broken-swirl ribbing is a mold-blown decoration that has two sets of ribs. No, not the kind with barbecue sauce on them! This is done by blowing the gather in a vertically ribbed dip mold. The glass is then extracted and twisted to produce a swirled effect. Now all the glassblower has to do is redip it in the same or another dip mold to create a second set of ribs. Viola! Now you know what broken-swirl ribbing means.
