[QUOTE="2thm8kr, post: 115539, member: 1367"] In the instruction manual it clearly states to blast with AlO3 at 1-2 bar pressure on page 28. It was explained to me by Ivoclar's glass engineer that ALO3 damages the surface on the intaglio surface of the crown creating a weaker surface to bond to after etching. I think the key here is moderation and keep the blasting pressure low. [/QUOTE]
