| One option that has worked well for a number of projects is to take extruded foam, either pink or blue foam and actually draw rock work into the surface of it. You can get it at building supply places or some housing sites. It is usd for insulation on foundations. It comes in various thicknesses and can be sliced as thin as needed. The process is to layout the coarses of stone with a fine marker then use a Bic pen, or an object with with a small round tip to deepen your previous lines. You are almost making a master for casting except that once you have drawn/carved into the foam you can paint a slurry coat of hydrocal over it just to give the suface a coat to except paint or stains as you would use on a cast wall. Just don't paint the hydrocal on real thick or you loose your definition. With a little practice you can make very easy rock walls. Great part is that it is very cheap. A side note after seeing the pic, is that a new book just came out called "Black Smoke and White Iron". It is full of photos and descriptions of coke operations and some foundrys in Colorado from the late 1800's to early 1900.
