[chbot] [OT] Homemade Reusable Molding Material

[Mark Atherton]

Just bought something similar to this from an art supply company in 
Christchurch.

Somewhat suspicious when I discovered that it may have been molded in a 
cooking tray, so may have been home-made.

A quick Google search found

... which would be a hell of a lot less expensive than the stuff I bought.

Looks useful for casting resin parts from 3D printed prototypes (among 
other uses).
