They say there is no single thickness that answers every job. In a hollow signet example they say 0.50 mm might survive printing, casting and polishing but finish flimsy, and that 0.90 mm is a better choice in that case. For a support bar they say 1.00 mm is a good figure to start with. Vulcanised moulds are described as shrinking about 2–4%; cold moulds about 0.5–1%.
