This reference chart is a fast guide for mixing US Gypsum / K-60 Pottery Plaster for use in mold making and slip casting.  I made it to help me make the process a bit faster as I am always spending time calculating how much to mix, and inevitably I also cannot find the correct container with labels, so this has amounts in quarts, ounces, grams, pounds, as well as volume units in cubic inches.  If you notice something incorrect or think of something that should be added please get to me on instagram (link below) @redneckpaycheck .  Thanks!
