I built my first formicarium over the weekend using Perfect Cast! I purchased some 3x3 inch glass plates to fit the mold perfectly so I didn't have to bother with cutting it since I figured getting a clean cut would probably be the hardest part.
Unfortunately a little bit of sand moved and created some spaces where the ants can escape (see picture below).
I'm trying to determine the best way to do a spot job on this and fix it. I was thinking of either taking some more casting material and filling it in, or maybe using some air drying clay? I imagine the last option probably isn't as durable and certain ant species would be able to chew through it. With the first option I'm just worried about doing it cleanly which is why I was leaning towards the second since that would be easy to redo.
Any thoughts?
Other than that I'm happy with how it turned out. I think it would make a decent founding chamber. I figured starting small with a flat nest would be easiest to get some experience. Maybe its not fixable and I can just use it as a learning experience, but I was excited it turned out as well as it did.
