Ceramic Slip


What Is Ceramic Slip?

Ceramic slip is a liquid form of clay used in plaster molds to achieve various greenware shapes.   It is comprised of talc, ball clay and feldspar.  These ingredients are gathered from natural quarries found in the and are the basic component of all slips manufactured today.

Ceramic Slip should be prepared for pouring into plaster molds at the consistency of cream (roughly). Stir the mixture to ensure that it is blended evenly, being careful not to beat in air. Pour slowly to avoid air bubbles. Keep the reservoir area filled above the beginning of the piece to ensure an even thickness.

Depending on the size of your mold, you can generally empty the mold after only 5-30 minutes. Let the mold drain upside down for another 15 to 60 minutes (depending on the shap/ size of the item and the amount of humidity in youor area).

With a mold trimming tool, trim the spare (top of your your reservoir area) and remove your casting from the mold, never tear the spare off. Allow the piece to stand in the mold until it is sturdy enough to support it's own weight.

Mold can be cast more than once a day if they do not become too wet. The more water the mold absorbs the longer it will take to set-up on successive castings. Do not allow your molds to become saturated.
