As water is mixed with air on it's way down there is an evaporation that occurs. That equates to a cooling affect, like a swamp cooler. There are stories of Egyptians making ice by laying out thin pans of water in the night's arid breeze, super evaporation made ice.
I agree with the last comment, with the additional info. From 32 to 130 degrees is the answer with the understanding that as long as there is moisture within those temps you will get growth. At the point when the bread is completely dry there can be no more growth.
Yes that is a great primer. But you must let it dry completely. If you laid it on thick then at least 48 hours. Check the inner corners with you finger nail for any soft spots. If it's not very dry then you won't get complete adhesion.
Bauxite is also the most abundant mineral on earth's surface. Also, it is very important because deodorant is made from it. Imagine the world without that!!!
