Good to Know

Clean before processing. Wipe the processing surface before engraving or inner engraving, because dust, fingerprints, or oil can soften detail and create inconsistent results.

Handle with care. K9 crystal is durable but may chip or crack if dropped or subjected to strong impact.

Add color with Glass Painting Pens. Color in the engraving, then wipe the excess off the smooth glass. The pigment stays in the etch for a bolder finish.

More about K9 crystal. K9 is purer than regular soda-lime glass — no green tint, virtually no bubbles — which is what lets it hold a clean internal engraving. See Regular Glass vs. K5 vs. K9 Crystal.
