[QUOTE="Dean Mersky, post: 1023, member: 73"] I posted photos I obtained in an article I wrote for the JDT. It showed the oxide layer on high yellow noble to be at 1 micron, while low gold was 100 microns. In the photos the oxide filaments were better organized and thicker for the high noble and appeared much more fragile for the low noble. This might be only a characteristic of the metal brand shown, but research at Boston U indicated that the porcelain bond strength of yellow high noble and Captek were about twice that of low noble and NP metals.
