Figured I could give other some ideas to play with when they realize you can laser tile of other colours with and without titanium dioxide. 
Latest is a 2x8.5 with a satin blush glaze. Sorry it appears washed out. 
This was using the titanium dioxide method. XTool D1 Pro 10W 0.1 interval, 3000mm/min, 80% power.
“Failed” Emerald glaze on 4x4 (the glaze is supposed to be just green, but overheating causes the blue speckles).
Direct on the glaze; Snapmaker A350 with 10W 0.15 interval, 1000mm/min 100% power.
Just something fancy I threw together. 
on a violet glaze.
Same as above frog.
Finally 2x8 concave with beluga crackle glaze.
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).
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.
