In an earlier post I wrote about a project making "stone" tools from chunks of quartz glass. My thinking was, and still is, that using quartz glass is about the best material for making these tools. The concoidal fracture pattern in both man made glass and volcanic glass, obsidian, makes for incomparably sharp edges. While not the most durable they are arguably the sharpest blades around. As it becomes more of a reality I'm growing all the more attached to the idea of producing a conceptual art project that brings stone age and space age at least in some way full circle.
I finally got my hands on another, and larger, piece of quartz glass. It's not space industry salvage but it's a good starting place to hone the needed skills to use that salvage material if I can manage to acquire some. The piece I have looks like it is a cutoff from manufacturing some sort of large round lenses.
If anyone works for a glass manufacturer or the space industry, I'm still trying to source a piece of quartz glass from an observation portal!
