Casting Work

I cast the knobs from polyester resin that was dyed to correct brown color. That did not produce very good results because the resin has so high viscosity that there were constant problems to get the mold filled properly.

Then I tried casting with low viscosity polyurethane resin and that gave very good results. Looks like this is going to work!

Below is the the filled mold with the polyurethane resin components and brown dye, castings removed from the mold, reproduction and the original but which is which?
