Actually in the Verde Valley… 100 miles north of Phoenix and about 55 miles south of Flagstaff. We are about 1200 ft above Phoenix. At least it’s a dry heat… 
Yep, that’s why I’ve moved to TiO2… I hate scrubbing off the old paint with chemicals… When I need something done, I use LBT100, but that’s for co2 and fiber lasers.
This is just TiO2 and water on the tile… the other is a slate coaster. Both done on the fiber.
If you want to see some nice photo engraving, check these out from @Bulldog on his fiber
Good luck
