The Short Mountain did seem to be quite clear and iron-free which I saw before the phosphate I made got a chance to strike any. I've also never tested the moisture content of the sand I've used. I've just either been lucky or it's been consistent bag to bag with the Short Mountain stuff, so I guess just thinking out loud and wondering if that can vary from source to source?
It sure can.
Spruce pine found a new silica source that ya vastly improved the clarity of their glass. What ever they were using before would always yield greenish tints on thick work. The new glass is water clear.
