I put some (rinsed) sand and vinegar together and let it sit a few minutes and dumped it after I saw no bubbles. Hmmm, I'm debating on doing it again and letting it sit for a few hours.

I didn't see any bubbles, the vinegar was very clear, but I did see something in some pictures that made me wonder. It looked like out-of-focus stars in the background...teeny-tiny bubbles *or* some imperfection in the glass jar.... The grains, themselves, look like silica/quartz with a few odd grains "here and there".
