[QUOTE="SiKBOY, post: 78525, member: 1362"] It's not only testing the hardness of a re pressed ingot vs a pressed ingot, what about the affect of oral fluids seeping into the re pressed ingot over X amount of years. Will it gain strength and hardness or lose? Will the biting forces increase the strength and hardness of a re pressed crown or lose its integerity? That will be the results I would be interested in because thats the real Life situation that the material will undergo. The strength and hardness test of both samples straight out of a pressing unit doesn't hold any weight. Most of us can GUESS what will be the result but until proper testing can be done.... It's just guessing. [/QUOTE]
