The Art Clay Forms - Lump, Slip & Paper


Lump Form

The basic clay material is called "lump form." It comes in a sealed foil packet and is ready to use. Lump form is used to roll slabs, snakes and to mold or sculpt objects. Lump form can be thinned with water and used as a paste.


Slip (or Paste) Form

Slip (or Paste) form comes in a jar or loaded in a syringe. The paste form is used like glue to paste wet or dry silver clay objects in place, as a media for slip casting, for painting onto an object to create a hollow form, and for decoration. The syringe, which is thicker than the paste version, is used to extrude wire for decorating, setting stones, filling cracks, etc.


Paper Form

Paper form is a thin sheet of clay that can be used to make bezels for objects to be set before or after firing, used for ring shanks, and folded like origami. Shapes can be cut out with punches and applied as decoration.

Lump Form Product Properties

Lump Form - Art Clay Silver

Art Clay Silver can be fired as low as 1200F / 649C which makes it perfect for combining with glass, porcelain and ceramic materials, and is also suitable for firing with sterling silver findings or wire. Shrinkage is 8-9%. Because of the lower firing temperature, this clay be fired with a wider variety of gemstones, and glass colors stay true.

Uses This clay is perfect to be fired by itself or combined with glass or sterling silver wire and settings.
Workability Metal Clay can dry out very quickly, reducing its workability. If the clay becomes stuff during use, add a few drops of distilled water and knead well. Be sure to keep any unused portions of clay tightly sealed from air.
