flic.kr/p/rjPu5bUsing a mortar of 3 cups granite fines (well poured through a window screen) and 1 cup lincoln fire clay I placed the bottom 2 rows of tile on my brick stove. The top 2 rows are the same formula plus a quarter cup of sodium silicate. Aftrr drying the drying the water glass mortar can not be abraded by hand of course the plain mortar is as crumbly as you would expect. For fun I also painted a small amount of water glass over the plain grout and it gave it a slick hard surface. Guess that's why they call it water glass. Next I'm gonna tear one of each off to see how well it adheres. Updates coming.

I really like the look. Tiles make anything look a little nicer. Have they undergone some thermal cycling yet?

flic.kr/p/qqtzTpAfter challenging a friend to pull one off they did. You can see from the photo that the water glass moved to the air exposed surface of the clay (lower right corner where it is darker) the mortar that was tight against the tile was not hard the way the air exposed clay was. I guess that means it moves to the surface we'll see see If the exposed clay hardens. The water glass only hardens the top millimeter of clay or at least that's what I observed. I applied the tiles today. I will let y'all know after a few more days aboit thermal cycling.

Your stove...
Single skin brick bell and bench?
Topped by tiles or what?

I researched tiles a couple years ago. If I remember correctly, it was better to use tiles that were actual clay or stone. There are so many cheap alternatives now. For decoration they are great but not for thermal mass.
Just a thought I am throwing out there.

I'm not saying they aren't good. Depends on the use. For instance, I was running across a bunch of concrete tiles. It was the fad here because they are so cheap.

I've been wondering for years if there is a anything that will stick tiles to a single skin stove and keep them there. The only one I know of was made by putting the tiles into the bottom of the molds and then casting the refractory on top of them. They've stayed on for 10+ years.

Those kachel stoves seem to hold on for a long time and according to some sources they just use fireclay and grog to hold them on. I guess its not to big a deal to just stick it back on if you use a non-setting mortar to hold it in place.

On a Kachel / tile stove the titles are usually structural, they're not just thin tiles like you have in your bathroom. Have a look on Youtube there are quite a few videos of people rebuilding tile stoves.

I have watched the videos and they are thicker than bathroom tiles but I wouldn't call them structural. The stoves I've seen were all fire brick on edge making a full stove with a shell of kachels although they were put up at the same time instead of after.

I tried placing 2x2 clay tiles around the top of my barrel,using just a fireclay sand mix. Looked really well for the first month ... then they started popping off. I tried painting them with waterglass and reapplying , lasted a few days. I plan on trying again this summer using a fireclay /sand /WG mix and see if they hold on better. Attachments:

It seems like the dissimilar expansion between metal and tiles would make them sticking impossible. Not to be a downer
