No effect on glass, even at 200/100%

Engraving newbie here! I wanted to create suncatchers from the old lids of candles, but no matter the speed/power settings nothing engraves the glass. I made sure the laser was focused. It burns into wood and paper just fine, but zero effect whatsoever on glass.

@richfaraone advocates for using laser transfer tape instead of paints. I haven’t tried it myself.
