Trying to calculate how much resin needed to fill a 1"x1"x6" mold. I come up with 6 cubic inches. If I use .554 as the amount of Alumilite in one cubic inch of volume, then I need 3.3 ounces of Alumilite Clear. So, how many grams of Alumilite Clear are in 1 cubic inch? Is it the same for Alumilite White? Thanks!
The mixed specific gravity of Alumilite Clear is approximately 1.08 meaning there is approximately 9 lbs per gallon. So how I would do this by weight is to multiply 9 lbs/gallon times 454 grams/lb which will give us a number of grams per gallon = 4,036 grams per gallon of mixed Alumilite Clear.
There are also 231 cubic inches in a gallon so we need to figure out how many grams we need per cubic inch. So if we divide 4036 grams by 231 cubic inches per gallon it will tell us we need 17.47 grams per cubic inch. To do 6 cubic inches ... multiply 17.47 times 6 = 104.8 total number of grams ... 52.4 of the A side, 52.4 of the B side. I'd probably round up to 55 grams or a little more of each side for what will be left over in the mix cup.
To convert that back into wt oz ... google tells us 17.47 grams = .616 wt oz. per cubic inch. Which multiplied 6 gives you a total of 3.696 wt oz to fill that 6 cubic inch cavity. Then divide that by 2 to see how much A side and B side you need.
Whew ... there is all that math we never thought we would ever need again back in school.
