I need to allow my bowls to get to a leather hard state but the instructions given were not quite clear on how to accomplish thisWhat exactly must be done to get clay to a leather hard state?
Using ceramic clay, you simply let it dry for a whileIf you need stiffness more quickly you can use a hair dryer and I recently saw a video of a guy who makes extremely thin large bulging vessels using an open flame from a blow torch to dry the material so he would work the lip/neck without distorting the lower partAir dry clay will sort of work the same wayPolymer does not work at all this way which makes making bigger polymer work require aluminum foil inside supports, etc.
