Ok so I know at least 3 makers who put their paint in molds and then attach to watercolor paper for their dot cards. Does anyone know what kind of molds to use? How long it takes for them to dry? I purchased some 12mm and 15mm round molds that can be used for chocolate, resin etc. I filled them and then put them in from of a fan to facilitate drying but after 5 hours they weren’t hard enough. So I popped them in the freezer for 30 minutes and they still were not hard. 
 I am going to leave them over night in front of the fan and hope they pop out tomorrow but would appreciate any insight you may have on this.
