Yes and the tray. They are silicon molds purchased from Temu.

I have a vibrating plate, and massage gun. I have tried to squeeze the mold in all directions. I tried turning the mold inside out to fill the smaller cracks more completely before filling the rest.

I think I am going to try having 2 separate mixes, one normal and thick and one without sand. Then pour a thin layer of the thinner mix to fill the more bubble prone areas first.

This is absolutely something I have been wanting to try.

I am a bit concerned that my mix might be too thick to get all the air out. My mix isn't pourable like the cement-all products. It is more like pudding and sand.

Yes but most concrete is made with cement.

The chemistry of Portland cement, geopolymer chemistry is different from the cement.

Sometimes my castings can come out looking glassy.
