Rock Lunchbox
Composites
Unfortunately my awesome idea for this week didn't quite turn out.

My idea was to make a rock-shaped lunchbox which would be lightweight but strong for carrying lunch. I also was interested in casting an irregular shape from nature to see how that worked out with the composite.

I found a great rock on a family hiking trip this weekend. It was a lunchbox-ish and also very rock-ish. I cleaned and dried it off and sprayed two layers of the 200 mold release. In retrospect, I should have COVERED the thing with vaseline and not bothered with the mold release because it totally didn't work!

The composite process was pretty straightforward and fun. I put a good amount of layers of linen on the rock.

I let it vacuum overnight just to be sure the resin had hardened and because I had several layers of linen.
