Lower Torso Moulage Mold Nº 3

Today I opened the 5 pound container of Moulage I ordered awhile back. It was well sealed. I had to use an X-Acto knife to cut around the lid in order to loosen it. The lid has a rubber gasket in it, so everything inside was very moist.

This is what it looks like inside, right after opening the container.

I split the contents of the container into six Atlas Mason jars that have tight fitting lids. I will also use these jars to heat the moulage to melt it, by immersing them in hot water in a pot. I weighed each jar, then filled each one with two 10oz plastic cups of moulage, then weighed it again. I added the differences together and the total was 2274.3 grams. 2274.3 grams X 0.001 is 2.2743 Kilograms, and 2.2743 Kilograms X 2.205 is 5.01483 pounds. I ordered five pounds, and I got five pounds.

I weighed everything on an Ohaus triple beam balance. It is accurate to within 1/10th of a gram.

Mold Math

I need to get an estimate of how much moulage to melt so I can fill the coddle. I measured the coddle, and I made a rough estimate of the torso by stacking a couple of oval shapes on top of each other. These are the numbers on which I am basing my arithmetic

These are the calculations:


First of all, the area of the mold rectangle is 6.75 inches by 4.625 inches, represented by recl and recw. The two oval shapes are 4.5 inches long by 3 inches wide for the bumm, and 2.5 inches wide by 3 inches long for the tumm. Each oval shape is 2.5 inches high.

The formula to figure out the area of an oval is L x W x 0.8.
Multiply the area by the height, and I get the cubic inches.
So the total cubic inches of the body is the tumm plus the bumm.

The area of the mold rectangle is the width X the length.
The cubic inches of the space inside the coddles is L x W x Height, which is 6 inches.

Finally, after figuring out the cubic inches of the space inside the coddles, and estimating the size of the lower torso, I subtract the body from the coddle space, and come out with the total cubic inches I need to fill with moulage. Did that make any sense? It took me a long time to figure it all out.

Once I have the total number of cubic inches I need to fill, I need to know how much moulage to melt. One cup (liquid) has 14.435 cubic inches in it. I have 145.3 cubic inches, so if I divide that total by 14.435, I get 10.06 cups of moulage that I need to melt. I just filled six jars with moulage, and the moulage is in very small pieces, so it looks like I will need to melt at least four or five jars of moulage?
