Good to Know

Handle crystal with care. K9 crystal is rigid but can chip or crack if dropped or clamped improperly during processing or setup.

Keep the crystal surface clean. Remove dust, fingerprints, or residue before engraving to achieve the best engraving clarity.

Check layout around clock cavity. Plan your artwork to account for the clock opening so key elements are not obstructed or misaligned.

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.
