"First, you might find it easier to work with everyday glassware as opposed to
crystal. Crystal contains a greater amount of lead, which retains heat very well
(too well for a laser!). When you use a CO2 laser to engrave glass, the surface is
heated as the laser beam blasts away delicate glass particles. If the glass is
unable to cool down adequately, as is sometimes the case with crystal, the
markings expand in size, which can produce a distorted look."
