If you would like, you can use a paint paddle to do this task. Simply attach the paddle to your drill motor, strap on your safety goggles and mix it up. Mix your porcelain to form the proper creamy consistency not too thick or thin. If the porcelain is too thick, the casting will come out with pour rings . Pour rings are circular marks left around the piece.
Thick porcelain is also difficult to drain.
If the porcelain is too thin, the piece will be very fragile and will most likely break in the mold. To thin the consistency, add a few drops of casting thinner to the mixture. Don t use water. Pour porcelain into casting pitcher. After the porcelain is stirred thoroughly, let it sit overnight.
