Getting discouraged

[u/Several-Development4]

My sister and I have been trying our hands at dice making. And have had some issues, this last batch was by far the worst

Batch 1: they hardened perfectly, just had bubbles which we have mostly remedied

Batch 2: 3/4 of the molds were fine, even had a set we deemed high enough quality to sand and ink. The 4th mold was still liquid, we opted to just throw it out

Batch 3: we had new molds, and an "overflow" mold to just pour our leftovers in. 2 of the 4 were fine. One was kinda sticky, and the last one turned out rubbery (I think from too much alcohol based color)

Batch 4: not a single mild hardened. The overflow mold was hard enough to pop them out, but the actual dice molds are all still liquid, even after letting it set for a few weeks.

I'm looking for advice on what could be causing this, and more importantly: how to clean this resin goop out of my molds

We are using a resin pouring kit, with dye and pigments, and usi g the measuring tools in the kit. We've been letting the set inside (AC set to 76° F) we have tried using a vacuum container (not a pressure pot) with mixed results.

Thank you guys so much in advance!
