I cast a bangle that was thin (0.6mm) and although it took a while to go hard (about a week) it has now. When I did another one it is still really soft and bendy after three weeks.
Is this because it is thin? Also would it help to mix a larger quantity of resin to get the heat going in it?
I don’t really want to give up on it because the mold was professionally made and cost a lot of money and I really like the shape.
I am using the Elichem Totalcast resin (I’m in the UK) and have had no problems with other pieces not curing, even small thin pendants.
