  10. Leave tumbler to cool

Note that its best to use a convection oven. All ovens differ so test yours to see what works best for you.  The more tumblers you do in the oven the longer you need to leave them for e.g. If 12min for one do a minute longer for 2. It’s like baking a cake. The bigger the cake the longer it must stay in, for the batter to bake  However test to see what works for you.
