A two part silicon was used for the silicon portion of the mold. Two cups were needed to measure out the quantity of liquid needed. for each cup, 775 grams of part A were mixed, then 75 grams of part B for a total of 850 grams. Each cup was mixed up thoroughly by hand then put in a vacuum chamber to degas the mixture. During the degassing, the inside of the box was sprayed with a mold release. Once each was degassed, the mixture was slowly poured into the mold box. The box was checked for leaks and left to cure for 6 hours.
