Oh, cool. One of the most common glass batches (raw materials melted to make glass) used by artists is "Spruce Pine Batch".

Wonder if it’s the same stuff or if glass people get a different bin.

The quartz is crushed and sorted for purity so yes it'd be a different bin than the stuff going to make fused quartz for semiconductors.
