Normally when engraving tile, glass, slate, etc, I use a protective layer of Dawn liquid dish soap. This time I’d already sat through waiting to see how much time it would take…(the first one was 7+ hours at 340dpi) I settled on 195dpi instead…only 4 hours. Anyway, I wasn’t willing to lift the lid just to put the soap on the tile.
I was surprised at how crisp the edge lines were. One tile did exhibit surface cracking; next time I’ll prep them better. In this engrave, there was no other damage.
