I am interested in producing bars that are 2-1/2″ high by 1-5/8″ wide by 5/8″ thick. Do you see any problem with drying a bar of soap this size, such as curling while curing? Is there difficulty in cutting a bar so small?
You can stack bars on edge, as thin as 3/8″, kind of like dominoes and then on top of the row lay other bars flat to bind the row. Bind two rows together with this same layer. Space the bars on edge about 1/8” (3mm) apart This way you can move them on trays and it allows them to dry quickly without warping and without needing to turn them. There is no difficulty in cutting a bar this size.
