While playing with my new-to-me laser, I made some tiles that needed a home versus place on the shelf.
I bought a diode laser for my wife to help her with etching her fused glass art work. Of course I had to "check it out" and set it up, what good husband wouldn't assist his wife with a new power tool?
The tiles are the standard white 6"x6", at $0.40/ea. perfect for experimenting.
My test was with the NWT method (Norton White Tile) that used Titanium Dioxide as the media. TiO2 is the white powder used to make paint white. It is actually a black mineral, just appears white when ground up due to the way it refracts light.
The TiO2 is mixed into a binder to create an inexpensive paint with a high concentration, I used watered down PVA glue for this.
The tile is painted and the pattern then can be etched with the laser. It takes some amount of testing to get the proper mix and laser parameters for that "perfect" black. One can image gray scale photos with amazing fidelity, these tiles were to just get the pure black correct.
The TiO2 is actually melted into the tile glaze and is as permanent as the glaze itself. The patterns are some line art I had handy and I will place these in the gallery for anyone who likes these kind of things.
I could have used other tile colors which would have been better aesthetically, but hey, I had to get these test tiles outta my shop! 8^)
On to the frames
Woodworking here 8^)
Frames are from salvaged red oak, grooved for an internal plywood base and finger joined corners
The plywood base keeps the tiles slightly raised from the frame.
Inset fuzzy feet were applied to the corners.
I fumed the oak for a while to darken it then finished with pre-cat lacquer.
Tile was sealed to the sides with white bath silicone caulk to keep moisture out and secured to the plywood with contact cement.
Anyhoo, this gave me some more ideas for "helping" my wife with her new tool 8^)
