The black on the pattern is graphite to keep it from sticking.
By the way, my son has a 1956 Buick Century.

He had used a router to route out his name by hand and poured Pewter in it and busted it out. I routed my son's name in reverse using F-engrave and used the rails on the back half to hold the letters together. Just for this test, I cast the letters with hard type lead. Next time I'll route the letters a little deeper and cast it with Pewter. I have to be a little careful with that, the pewter is $16 to $20 per pound. The Lead is less that $1/pound, I don't have near that much in it. I've several hundred pounds of old letterpress type. The name pattern is still fine and can be used again. The back piece with the rails broke when I tried to get the piece out.
