What are the most interesting print materials you've seen?

Lukas, I'm really interested in your description, since I'm about to try printing gum on some ceramic floor tiles that the previous owner of the house left here. These are glazed, not shiny glazed but smooth and slick enough that I'm going to need to fashion some way of helping the gum adhere. I'm thinking I'll sand the tiles and then use pumice in acrylic to add tooth. Then if I could print gum on that successfully, I was thinking of using some sort of sealer on them. I'm not clear from your description; were these unglazed tiles that you printed on and then glazed and fired? That would probably be the most reliably durable way of printing on tile.

Katharine, I printed on tiles which were only bisque-fired at about 700 C°, and had yet to receive their glazing (at 1250 C°). The tile was then to be glazed with the image on it, and when there was a transparent glazing over it, the image became really a part of the glazing, with beautiful shadows and an absolutely unique quality. The only pigment with which I succeeded to do this at this termparature was cobald oxide, so the image was blue. Iron oxide worked without a pransparent layer over it; the glass over it somehow "gnawed it away". I suspect it would work, however, at 1050 C°, as would probably other pigments.
Tiles are quite fragile and porous when bisque-fired, and suck up instantly any fluid (your tongue sticks to them when it touches the surface). I had to coat over this surface in order to be able to print an image on it, which, however, made the subsequent glazing layer much more difficult to apply. That was the problem I was still fighting with when I had to abandon my experiments for the time being.
I might, however, be able to pick them up again in some time.

Thanks, Lucas, that's very interesting. I may have to abandon my experiments because I can't find any way to abrade the glazed surface enough to take a substrate. Even very rough sandpaper doesn't scuff it at all.

Mike, no we have not set a date yet. Still need to plan some things and I will be sure to let you know when we set a date.

3D prints made from slides taken with a 3D camera.

Talking photos in frames.

3D prints that move as you walk by (as seen in "Back to the Future 2").

Those are three of the most interesting.

Ok,thanks Jim.
