Description
To make your cup:
Print out the four files in TPU, at least 4 walls--but 6 would be better.
Paint on a thinned-out release. I use Murphy's oil soap--but any water soluble soap is fine
Mix and Fill the molds with No1 Ceramic Plaster. I like Andrew Martin's ratios.
Wait for the plaster to cure, but not too much--you want it to be still warm while you remove
Bind the handle molds together, and wait for the molds to finish curing
Casting Instructions:
Handles: Fill with slip, leave until body is ready to remove
Base: Fill with slip, leave until body is ready to remove
Body: Fill with slip. Wait 10-11 mins--check thickness of overspill. Target thickness is 2-3mm, but thicker is acceptable. Empty of slip once desired thickness achieved. Wait at least additional 30 mins, or more depending on ambient humidity and temperature.
