The examples are polymer clay and the description of techniques

 are common terms used in working with polymer clay.

The silicon texture sheets do not need a release agent 

when used with polymer clay.

 The soft edges are wonderful for impressing smaller areas or working repeats.

This is the most odd and amazing texture, very tiny lines and craters.

On this example, PearlEx was lightly rubbed on the out-y part of a texture sheet,

the clay sheet was impressed, then PearlEx rubbed on the out-y part of the clay sheet,

then the clay sheet rolled flat.

The next sample is the same technique, with different Pearl-Ex pigments and 

 a layer of Kato Liquid over it. 

 I just had to show this pen !!

 Now this is cool. The textured sheet of polyclay is baked. Liquid Kato is rubbed on, then Pearl-Ex powders(mica) are applied. This is heat set. Next layers of the Kato Liquid are applied and heat set until the surface is glassy. (is that a word ?). I left this with a little texture, I like the pens bumpy. 

The picture just doesn't do it justice, this really shimmers.
