The Art Clay Forms - Lump, Slip & Paper
Lump Form
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 med ia for slip casting, for painting onto an object to create a hollow form, and for decoration. The syringe, which is thicker than the pas te version, is used to extrude wire for decorating, setting stones, filling cracks, etc.

Lump Form Product Properties
Lump Form - ACS Standard Slow Dry
Lump Form - ACS Standard Slow Dry

Art Clay Silver Slow Dry dries slower than other forms of Art Clay Silver. This special formula allows for braiding, weaving, and generally gives the artist up to 5 times more working time. It is a wonder for those who live in excessively dry areas. We recommend the unfired clay be no more than 3mm thick. You can make large items, but they need to be layered, such as flower petals, so the pieces will dry properly. Slow Dry elements can be combined with other Art Clay types and fired together. During firing this clay shrinks between 8-10%.

Uses Braiding, fine detail and molds.
Workability ACS Standard Slow Dry dries 5 times slower than ACS standard, which gives a longer working time. Be sure to keep any unused portions tightly sealed from air because all metal clay dries very quickly when exposed to air.
