What will Titanium Dioxide (TiO2) stick to other than ceramic tile? Will It TiO2?

I have been working with titanium dioxide for a while now and have gotten my ceramic tile process down. I asked myself, what else could I use TiO2 on and get similar results? I tried a few materials and this video shows the results. Some things worked while others did not.

Great content, well shown. On the clear glass piece, I wonder if it's necessary to remove the TiO2. Perhaps with an inverted image engrave the glass "back" and then seal over the TiO2 with a clear varnish or perhaps colored spray paint. I think I'm going to give that a try.

The only thing I can think of on this idea is that the un-lasered TiO2 is not adhered to the glass and is easily brushed off. You would have to be careful with that. It would look really good with the nice white of the TiO2!

@@CNCATHome Your spot on about the loose TiO2, thanks. I think I'll print a handling frame for the glass, something that can be left in place during lasering and coating and with a lip for easier handling.

Ok, so the glass etching a negative was wild. I would not have guessed that one. So here is an idea for you to try on glass... flip the image to a negative in software. Burn it to TiO2 glass and then try edge lighting the whole thing.

[@CNCATHome]

That is interesting. The TiO2 is on the surface of the glass. I don't know how well edge lighting would work? Interesting. I guess you don't know until you try.

Was just thinking same.

[@youeladamas7840]

Very nice I do something similar. The white wash on wood can look nice too but then needs a clear coat seal.

[@CNCATHome]

With a good way to seal that on, it would have a great look in the right circumstances.

Awesome

You should have sprayed the glass with that Rustoleum mirror finish spray.

[@CNCATHome]

That is a neat idea. I do have some shinny silver spray paint I could have used. That could look very cool! I may have to try that sometime. Or another metallic spray paint.

cool man

[@markgreer6585]

Your TiO2 coatings appear very smooth and uniform. What blend are you using and how are you applying it? Brush, spray bottle, air brush? Thanks.

[@CNCATHome]

Good question. At the time of this video, I was brushing my TiO2 mixture on with a foam brush. Since then, I have started using an airbrush which puts on a very nice coat. As for my mixture ratio, I don't know. I was a bad scientist and just started mixing it until I liked the consistency. Since then, I have added more alcohol to thin it out which seems to work better. I think I am somewhere around 3 to 1 (three parts alcohol and 1 part TiO2). This process is very forgiving. There is a wide range of mixtures that seems to work well. I hope this helps.

THANKS!@@CNCATHome

How about Ti02 on the front of a mirror

[@CNCATHome]

Great questions. If it is a glass mirror, it would work great!

[@lisaburnham7151]

Did you invert the image like you do on the white tiles?

[@CNCATHome]

That is a great question. I do not invert the images for this. I normally do not have to. It all depends on the image and what I am doing. With this method, the TiO2 turns black where the image is black. Thank you for asking.

[@brucemilyko8549]

I wonder what it would look like if you need a negative image on a titanium oxide coated glass.

[@CNCATHome]

Very interesting idea. That should work just fine. I have done quite a bit of B&W photography in the past and this look so much like a glass plate photograph. But a positive, not a negative. If I still had all of my B&W photo stuff, I would be tempted to see how it worked to make a photographic print.

Stainless steel is suitable?

[@CNCATHome]

I have not had good luck getting TiO2 to work on metals. That doesn't mean it won't, I just haven't figured out how yet. ;-) I tent not to work much with metal so there isn't much opportunity for experimenting.

[@johnsathe2429]

It's good on stainless, actually stainless is good without the TiO2.

[@CNCATHome]

@@johnsathe2429 - I have had good luck with engraving on SS if I don't do too much. I have over done it an my material warped. Too much heat and internal stress I guess. I should try TiO2 on SS sometime. Not sure I would use that method as SS seems to etch nicely without it. 🙂
