So today I'm going to show you how to make a alginate mold and fill it with polyester resin.
What do we need;
- alginate (it is the material dentists use to cast your teeth, there are several versions of it; some harden quickly like in 1-2 minutes and others take 5to 9 minutes. I used the latter.)
- room temp water
- mold containers
- polyester resin
- polyester resin catalyst; Methyl ethyl ketone peroxide (MEKP)
- a mixer (you can mix the alginate with your hand but a mixer would make your life a lot easier. but you need a mixer for polyester and the catalyst. If not mixed well the product would crack while hardening)
Alginate won't become hard like a rock or plaster. Instead it would be like a pudding but a bit more firm.
Wiggle your hands out of the alginate and voila your mold is ready.
I didn't have a mixer so I just mixed it with a brush but it was a risky thing to do. It should be a clear green color.
Wait 1 hour and take them out.
