I cannot figure out what I’m doing incorrectly here.
I’ve used different kinds of resin, including casting. I am using exactly the correct amount of hardener to resin. And stirring VERY thoroughly, followed by a vacuum chamber to remove the air.
But still, when the resin sets in my mold it pulls away from the corners. 🙁
I’ve lost 2 gallons worth of resin so far to this.

It looks like you are having a lot of shrinkage due to heat production. Are you using a polyester resin by chance?

the layer is too thick, or was too warm in room, try cast in two laver, or in lower room temperature

This is what I used for this last one.
I use it in a cool workshop, but I guess I can dip the mold into cooler water as it heats up. I’ll try that.
I’ve tried layers, but it just doesn’t work for this project where I need color swirls going through the whole block. There would be no way to make it uniform.
