Shaping Creations


From what I can tell the difference between concave and convex may be described as follows. If you set a concave pendant face up on a table, it would be able to hold water. If you set a convex pendant face up on a table, water would roll off like it would off an umbrella.

I use the lightbulbs to place a piece on to dry in a convex shape. Obviously, my texture will be up or on the top.

I made the above stands by screwing a lightbulb into Fima or Sculpey or another brand of polymer clay. I pressed them firmly on a flat surface so they stood upright. Then I baked them in a conventional oven at 275 degrees Fahrenheit for 15 miinutes, following the recommended polymer process. 

Notice different light bulbs offer different degrees on convexity (that is a real word, meaning measure of the curvature). Here is a small Bear dried on the middle lightbulb.

To make a piece that is concave, again with the texture on top or visible in the bowl, I place my piece in a cupped dish to dry. Here is an example of something I use, empty containers of Mega Mold.

Shaping Concave

To give a piece a slight arc, I simply dry it in the shape I want, using whatever I have on hand to create that.

Drying 1

The pendant below was dried on a rectangle of transparency plastic, bent and taped to the shape or curvature that I wanted. I secured it standing straight up; because as you may know, when clay dries on uneven surfaces, it typical lifts itself and falls off whatever surface you wanted it to stay on.  Clay is like that.
