Too thin, breaks too easily

My slab is about an ounce, but for some reason it's too fragile. Any tips on working this out?
Also, some pics I see of others the slab doesn't have any holes in it. How would I do that? And the edges dont keep at a perfect square. My OCD is killing me here haha

I infer you are pouring early. If you evaporate more LPG before vacuuming, the bubbles won't be as large. If you heat it hot enough to melt, it won't leave big holes behind when the bubbles burst.

That makes a lot of sense. I use slightly lower than room temperature water (because I dont want to use any electrical heaters) and I put the oven for 83.5F

Dude it has nothing to do with pouring it early. It’s too thin. Make your paper smaller. Make it thick. My friends want it how yours is but I make it too thick. 200 gram slabs and they complain lmao.

I suggested that it was an early pour due to the size of the bubbles, suggesting copious quantities of LPG present.

We extract as cotton candy, which is arguably the other end of the scale and doesn't present the same issues. Everything is expanded into foam, but no bubbles fighting to escape from a sub melting point matrix.

I suggested low temperature because the bubbles didn't heal. At melting point that isn't an issue.

Thickening a slab, most certainly involves surface area versus volume, so good point as one of the pertinent details!
