09 Plaster Production Molds Nº 285
I used a couple of the coddle boards as spacers to roll out a slab of clay for the build-up. Click on the image to enlarge it.
Because this is a very simple mold, I am only giving one inch around the pattern, instead of the usual one and one-half inches. The skullcap is 0.75 inches tall. The build-up is 4.625 inches by 4.500 inches square.
# Mold Volume in Cubic Inches
36.42187 cubic inches
# Two-thirds volume is water
24.40265 cubic inches
# Cups of water (14.44 cuin is one cup of water)
24.40265 / 14.44
# Water weight
1.68993 * 8
# One part by weight 13.51944 / 2
# Three parts of plaster
6.75972 * 3
I will need about 13.5 ounces of water and 20 ounces of plaster.
