I just did my first two and three color laminate.
No pictures, and they really aren't that impressive.
But it wasn't that hard, and that's why I'm posting.
I had made a twelve cavity Ika body, two part POP mold, hand pour.
After reading about split cups here, I started wondering if I could just pour some of one color into the open half of the mold, and then close it and pour the other.
Short story long, it worked. Hot plastic on the second pour makes sure the two melt together, but the colors stay separate.
I got a bee in my bonnet, and tried three colors, hand pouring both the first and second colors into one half, and then closing the mold and pouring the third color. It worked, too.
I'm posting because it isn't hard, and I wanted to encourage others to try.
The pouring sprue hole for my Ika molds is approx. 1/2" diameter, tapering to 5/16" where it meets the cavity.
I also tried the feather in between the two mold halves idea that Toadfrog invented, and it worked too.
I guess that makes me a GIT...Genieass in training.
