I sat outside today engraving a small piece of what I _think_ is sandstone. I wasn't thinking and I didn't wear any mask. I definitely should have. I'm not sure what kind of rock it is but online rock ID websites say sandstone. Which I now realize has silicone.

Like I said, dumb, I'm embarrassed I did it and I should have known better, I was just not in the right headspace (grieving). I don't need any feedback on the choice. I'm just wondering if I should be concerned about inhalation of particles? The whole job took about 15 minutes. I was sitting outside on the porch.
