This is a step by step tutorial on how to slip cast. Slip casting can be useful for making multiples of one object and to make casts that are hollow on the inside. This tutorial is demonstrating how to slip cast porcelain in an already existing plaster mold easily and efficiently. For a tutorial on how to make a plaster mold please refer to the "Plaster Mold Making" tutorial for more information.
Step 1: Materials Needed
Below You will find images of the materials needed to complete this tutorial. The materials needed are as follows:
Large Rubber Bands
Paper or plastic coffee cup
Clay Cutting Knife
1 Gallon Porcelain Slip Ware (can be purchased at The Standard Ceramic Supply (http://www.7ceramic.com/)
1. Turn your one gallon of Slip ware horizontally and roll back and forth for 5 minutes to get the slip well mixed. You can also shake the gallon up and down but keep in mind it will be heavy.
2. Take the empty plastic/paper coffee cup that you gathered from the materials list and fill it up with slip from the 1 gallon container. Once you have done this place it aside for now.
3. Get your mold ready by making sure the inside is clean and dry. Match up the two halves of the molds by making sure the pinholes are aligned. This will ensure a sealed closure and no leakage when slip is poured into it. This is a mold of a snow man and pumpkin that was casted from plastic toys. Intricate molds and pre-made molds can also be purchased at ceramic supply.
4. When the two halves of your mold are together fasten them with the large rubber band. Make sure they are nice and snug. This will keep the two halves together and further ensure no leakage.
5. Once you have placed the rubber band around your mold and secured it, flip the mold hole up.
