ABSTRACT:
The height of protrusions formed during laser texturing a glass-ceramic substrate is controlled by controlling the amount of the crystalline-phase of the substrate, to less than 70% by volume. In an embodiment, the amount of crystalline-phase is controlled by heating under controlled conditions to convert a glass substrate into the glass-ceramic substrate comprising a controlled amount of crystalline phase.
