Sorry tony, I must have missed that in your earlier post, but I certainly agree lol

When I was talking about voids I was thinking of interior voids. Reading back though I phrased it very poorly. What I noticed -when there were lots of small features, the features sort of “used up” more of the epoxy content of the EG, and there were more voids throughout because there was less epoxy for the remainder of the casting. That was my impression at least, I wish I had been taking videos for YouTube back then as it was a really interesting effect.

Frank- I bought my stone from a landscaping store where it was stored outside, so everything even my sand was quite wet. I rinsed the fine dust off everything then dried it in trays in the oven which seemed very effective

I don’t know how much the fine dust effects things, but I had read that theres a minimum coating thickness of epoxy. Like no matter how small the particle, to coat it completely you need at least a layer of epoxy around it that’s a certain thickness. So very tiny particles end up not being very effective for lowering epoxy percentage, and just make the EG harder to mix. Has anyone heard anything similar to this? I think it was a paper by LeGarde or something like that (old paper like at least 50 years old I think)
