Some artists prefer glass or tile as a work surface because they can help keep clay cooler if the artists has rather hot hands. They can also go directly into the oven with your project. In fact, at lots of retreats, small tiles are used as baking surfaces, because several can be placed in the oven at one time.

In respect to this, how do you keep polymer clay from sticking to the surface?

BAKING SODA is my favorite! Baking Soda is an old timers remedy for everything! It's a fine powder, makes a nice resist and bed on which to bake clay items, and washes off easily and cleanly.

Beside above, do you paint polymer clay before or after baking? Paints (and the supplies that go with it) are another must have for most polymer clay artists. I prefer acrylic paints and in many cases "heavy body" acrylic paints, but any type of acrylic paint is safe to use directly on polymer clay. You can use acrylic paints before baking OR after baking your clay.

One may also ask, what can I use to make my polymer clay shiny?

Polymer clay is not glossy after baking. You can sand, buff, and polish the clay itself (see below), or you can apply a glossy varnish. To make your clay project less shiny, you could apply a matte varnish. Note that adding a glossy varnish can make translucent polymer clay seem more clear.
