QUOTE: Originally posted by ndbprr The basic way to make a mold is to buy some liquid latex rubber that comes in a quart jar ib the US. You choose the object you wi***o mold, clean the surface preferably by washing and scrubbing and them start painting on layers of latex rubber in this case about every ten layers I would put some gause in it for strength and do about twenty layers with a throw away cheap brush. Don't do it to thick at a time or it won't dry properly and will stay gooey in the center. Then just mix plaster and make your rocks. Rock molds are available in the US already to go for under $20.00 in variety of sizes (at least they were at one point). You might check EBay also and get lucky.
QUOTE: Originally posted by ARTHILL I bought a bunch of Woodland Scenic molds and like them a lot. I have filled them with all different kinds of plaster. Plaster of paris is the cheapest here. WS light hydrocal works but is very expensive. I keep all the waste, dye it and use it for talus. I model mountains and have used a coffee can full already.
