Why does my shatter look like this?

This is from an ethanol extraction. It’s been in the oven under full vac for 3 days now, flipping every day.

I’d like it to be smoother and less bumpy.

I just re pressurized the oven and am going to let the slabs sit under atmospheric pressure with heat to see if that helps. If not, I’ll try to warm it up more with a heat gun. Any other tips?

Looks like you need to spread that initial pour a lot more thin.

I’ll give that a shot next time, thanks. I rotovapped too much ethanol off I think, so when I poured it it was pretty thick and didn’t spread well.

Yeah thats a common mistake I hear about on here. You can come off the roto with about 10% EtOH and get some slabs done in as little as 2 days. All dependant on strain of course.

Keep it on heat no vac it’ll smooth itself out
