Creating Artifical Rocks

I WILL BEGIN THIS ARTICLE BY EXPLAINING THE different
types of effects that can be achieved using my carved foam method for rocks.
As we all know, rocks come in every shape, texture and color imaginable, but
knowing how these are created in nature is the trick to reproducing them
accurately. The advantage to using foam is that it can be fractured, shaped,
flaked, etc., as real rock does. After you've done this to the foam, all
that is needed is to cover it with a texture that can be painted.
3 Here is artificial sandstone, also made from
concrete. Sandstone is so bizarre in the way it forms, you can get away with
just about anything when re-creating it. Notice the many different shapes
and textures in the surface of the rock, which

These photos show examples of highly fractured basalt. This rock is carved
concrete, but can be duplicated exactly using this foam technique. Each type
of rock has rules on how it forms, so we use these rules to reproduce it.
For example, this basalt has no bellowing shapes or bulges, so we carve flat
or scalloped faces. Next, these faces are not on the same plane; some
protrude while others are inset. The fractures are irregular--they get
narrow then wide. Whenever two fractures intersect, a piece of rock pops
out, leaving a wide spot where they cross.
