With our process, you can make one tile or stone per day, per mold. If you have a large project, you may want to consider ordering a sufficient quantity of molds, based on the number of stones or tiles needed, and your work schedule. As an example, it would take you 10 days to produce 100 square feet of tile using ten 12x12 molds, 20 days using five molds, etc. NOTE: You should never force or rush the curing process... remember "drying" is not "curing".
