Amaco Marblex - Finished Sculpture

The photo above is a little overexposed to get rid of shadows. Marblex doesn't come out quite that white, but it does look nice.

 I like Marblex. Now that I'm done with a sculpture and it's completely dry, I know how hard this stuff is: pretty darn hard. I don't have anything to test breaking points of different materials but I'll tell you what I know. Check out my other article on Marlbex for how it sculpts.

Somebody asked if you could add new clay to dry Marblex. Yes, and it works well. Wet the dry stuff and it gets soft, add the new stuff. It shrinks very little is one reason it works, it doesn't pull away from the layer beneath. I thought this stuff would be easy to sand like paper clay. It's not. With 400 and 600 grit sandpaper I can sand paper clay quickly. Marblex doesn't sand, it burnishes, which is nice; a polished stone-looking texture emerges. It's so hard that the sculpture sanded the sandpaper and tore the grit off. I had better luck with 1500 grit. Seems the smaller grit is just right to burnish the piece without the grit coming off on the sculpture.

Because I thought it would sand easily I didn't worry about getting every blemish and bump out before drying. I used the wet scrubby pad side of a cleaning sponge to smooth out the surface. Problem with that was little bits of the scrubby stuff would come off and get stuck in the wet clay. Gotta find something better and smooth the piece before it dries, save some trouble.
