I vulcanized a popsicle stick in organic rubber, then cast pewter in the cavity. The stick came out of the mold thinner, like a coffee stir. The wood grain was more dramatic. I’m definitely going to experiment further since I have many popsicle sticks left.
Vulcanization involves 350°F and about 50 tons of hydraulic pressure. It stinks like a tire store, too.

in spite of all these negative effects, something beautiful comes out..
