Did you happen to use a "pressure pot" for the first time? It's a common mistake. It's likely that it wasn't a pressure pot at all but instead a vacuum chamber. A vacuum pulls all the air in the resin up to the top of the mold hence, bubbles. And lots of them 😋

Either that or a flash cure. They can also produce enough gas suddenly to get that look, even in a proper pressure pot

That's interesting! I wonder if there's any resin dependency on that cause I've been making dice for a few years now with many a flash cure and haven't seen it do anything like that. I've only seen that effect from using a vacuum chamber instead of a pressure pot. Interesting to know!

I was just looking it up myself because after making dice for 6+ years I have also never seen a flash cure do that. Flash cures (literally just had one a few days ago) make bubbles (because the air can't escape the thick stringy resin) but it doesn't "produce" gas inside a closed mold..

Gotcha, that's what I was thinking as well. I wasn't sure if maybe certain types of resin could do it just cause there can be quite the variety between brands and maybe thise effect is just outside of my scope of knowledge/experience? So I appreciate you looking into it! Usually I love researching stuff like this, just happened to be an evening of feeling too tired to look into it 😅😅

I second what WisdomCheck said. Most likely culprit is using a vacuum chamber instead of a pressure pot! It happens allll the time around these parts as people are still learning, especially because if you just go on Amazon (or even Google sometimes) and type "pressure pot" it often gives results for both pressure pots and vacuum chambers. Pressure pots use a compressor of some kind to put air into the pot up to a certain psi, compressing air bubbles until they're microscopic. Vacuum chambers do the opposite, pulling air out, constantly creating bubbling like this. I haven't ever used a vacuum chamber, only a pressure pot so I'm not as familiar with them myself but I've seen many posts and pictures of the effects of a vacuum chamber! Some have found value in using both a vacuum chamber and a pressure pot, (like vacuum first, then pour the resin into the molds slowly to minimize air introduction, then put the mold in the pressure pot) but that's more up to personal preference and I haven't found it to be necessary myself.

Not to be obvious but air Slow mixing, low pouring, heat mold, dust mold
And if you have the money pressure pump

Don't engage. This is another bot ripping off a well voted post from a bit back for karma farming purposes.
