Glass brush not necessary
I wrote earlier about the glass brush being helpful, but after many different experiments, I’ve found it’s not necessary. A toothbrush with dishwashing detergent is all I use.
I also do not do progressive grinding. I am using a Ryobi tile saw with the QEP Glass tile blade from Home Depot, about $26. The disadvantage is that the “kerf” (width of blade/cut) is a little wide, but you’ll probably not ever cut your fingers on it. I do NO GRINDING on my pieces whatsoever. (I also cut on a small diamond glass bandsaw, but I follow the same cleaning steps for flawless results.)
I put the pieces in a bowl of water with Dawn detergent in the sink, run the water, scrub the edges of each one with a toothbrush, then rinse, and put into another bowl in the sink full of clean water. When I’m done scrubbing them all, I rinse the bowl full of glass, pulling out pieces, and putting them on a clean kitchen towel (not paper towels, although this would probably work).
I now ONLY use a kilnwashed shelf. Although I religiously use Thinfire shelf paper for other projects, I do not use it for pendants. I don’t know what happens, but my guess is that the Thinfire creates dust that is attracted somehow to the ground areas of your glass pendants. I’ve tested this many times, and each time I use Thinfire, I have at least some of the pendants come out with gray haze.
Although it’s a little more work, the results are worth it.
