[QUOTE="CYNOSURER, post: 23629, member: 672"] Help me with my rudimentary grasp of physics. Accepting that Ivocap does indeed heat from the bottom up due to the design of the flask, Physics tells us that ALL matter expands when heated. As the denture cures...bottom to top...shouldn't that expansion be pushing material back into the reservoir? Physics tells us that ALL matter contracts when cooling. Isn't this (as with casting metal) when the value of the reservoir is needed. And, isn't it too late for a denture that has been cured bottom to top to benefit from this reservoir? Just trying to wrap my head around it. Thanks for bringing this up and your patience. [/QUOTE]
