Not wood, sweet gum seed pods cast in resin
Brad, How much pressure are you putting into the pot when casting these? Ever have any problems with the nooks and crannies of these pods?
I cast them at 60psi in my HF paint pot. Even with that, though, you will sometimes get some tiny voids--there are internal voids that aren't open to the atmosphere, so no resin can get into them. Because of that, I keep CA handy when turning. I also finish them with CA because it's a woody material.
