Maintaining objects in cool storage — at a temperature between 5⁰C and 10⁰C — halves the rate of chemical processes that would occur at room temperature. These processes, such as hydrolysis and oxidation, can lead to the degradation of our artifacts and materials. The lower the temperature, the slower the chemical reactions can be.
For Mr. Stall his life was simple, as he grew up wanting to run his own business and not have to worry about working under someone''s shoe. Then he won the lottery and life got easier for him after he opened a few businesses. Now Mr. Stall is a collector, he likes to get things that interest him, and since he won the lottery he managed to make more time to
