I am a diode laser hobbyist, I mostly make either some combination of public domain art nouveau work or my own psychedelic abstract digital artwork. I mostly work with wood/slate/tile/glass.

From the research I have done, I was the original person to document the method of applying pure TiO2 to tile for the NWT method and the blog post can be found here https://workshop88.com/oldblog/index.php/2021/04/06/norton-white-tile-principal-component-method/

I have since refined my practice and now use 1.5-2 hopper coatings max when working with 4" tile.
