I needed 6 gallons of rubber to make the molds for these two carvings.

Stuck halfway. Go forward or retreat?
It was an expensive failure and a lesson in sculpture economics. To finish the project I need an 80 lb kit. That's $462.44 of material that I can't justify right now. So instead of buying more rubber, I'm scrapping the mold, and going to show the prototypes instead of casts.
The mold rubber I use is called Poly 74-45. It's made by Polytek, a company in Pennsylvania. I went online to see if I could get it directly from the manufacturer and save some money instead of buying it through Fiberlay, our local Portland supplier.
Polytek sells an 80 lb kit for $440.00, Fiberlay sells the same for $462.44. Their markup is only $22.00, which includes shipping it across the country! Comparison shopping made me realize what a slim profit margin Fiberlay makes on this product. A little understanding makes me appreciate them much more.
All this goes to show some of the material costs (and emotional costs!) involved in making sculpture.
