Same as rose. I focused it at the bottom of the curve, so it defocuses closer to the edge and fades. Gives it a nice aged look with the crackle glaze.
Just some of the experimentation I’ve been doing, the TiO2 method works really well with unglazed tile as well! Do a laser project, then glaze it with a semi-transparent later. (this is still on my to-try).
The engraving itself isn’t a fail, it’s one of my faves. It was the glaze that “failed” and thus made it scrap, so I claimed it. It’s not supposed to have the blue spots in the green, which I personally like.
