Pottery Plaster Mixing Directions For making Plaster molds use the following ratio:
3 Lb. Plaster/2 Pints Water

This will make 80 cubic inches of cast plaster.
To calculate a specific mold size multiply the mold's Width x Length x Height in inches. Divide by 80 to give you the number of quarts needed for your specific mold. Use the same ratio of plaster to water above to establish the amount of plaster to use for your specific mold.
