Introduction: Convex Glass Tile From Bottles

Step 1: Jig? Yes Please!

There are really good bottle cutting jigs out there, but I loath to purchase, store, and ultimately yard-sale a specialized tool.  So here is the simple, flexible, and repeatable setup I use to cut glass cylinders:

Step 2: Cut the Long Cuts

Time to cut along the infinite planes of the cylinder!
Remember that the glass must be fully supported under the glass-cutter.  This is where you would get in trouble with any remnant of the bottle's shoulder, as it will create a gap, a ruined bit of glass, and a debilitating wound.
Perhaps a firm-but-slightly-yielding material would fix this?  Or a setup akin to an English Wheel? 
Score the glass, than tap along the line.  The first cut won't visually separate but you will hear when it gives up the ghost.  Mark your next line, score, tap, the tile will fall off, et cetera.

Step 3: Finish

Figure out the style of tiles you want.  I think they look pretty cool left long, but to make shorter tiles (and to trim tiles for installation) rock them along a curved surface to score the convex side (this is for consistency sake; the cut will look different depending on which side you score).
Wash the tiles of the cutting oil with soap and water.  For consistency and to hide the thinset I painted the backs of the tiles with spray paint.  Experiment with colors and densities.  I used pretty cheap spray paint so I probably used more coatings than you might need.
So go procure some bottles and please post pictures of what you make!

    So I cut glass as well, and wondering what your thoughts on melting the glass just enough to get the curve out? I collect Dr Pepper and make small drinking glasses but always have the tops left over. So, I cut out the logos and don't really know what to do with them? They are really curved. And if you put them in a Kiln the color of the logos fades to white.

    I always wondered if a "raku" kiln got hot enough to slump the glass. The makeshift way of making a raku kiln is to do it in a metal trash can. You could put the glass you wanted to slump onto bricks and layer them about 1/3 of the way in the trash can somehow. Don't know if it would work, I was just thinking...I think most glass needs about 1200F before it starts slumping. Just thinking...

    Slumping isn't the problem, annealing the glass so it doesn't shatter when it cools is. Trying to get the glass to stay on the brick would be a second problem, the amount that the brick and glass shrink with the temperature drop is more extreme and would cause shattering-think exploding glass-unless you got extremely lucky.

    I think too much, about these wonderful recycled materials, but I also thought that a glass bottle with cut off top and bottom, then down each of 2 sides, and you would have a glass tile like the terra-cotta roof tiles from Mexico, but lighter. You could tile an outside small building with these, and it would keep in any heat from the sun for a greenhouse, etc. You could glue them inplace with marine silicone glue, couldn't you?

    I'll save this idea !…
    I also saw a transparent wall made from the bottom of wine bottle … this was pretty interesting, especially because the owner used green, yellow and blue bottles …
    (blue wine bottles are very rare these days : they used to sell white wine in Paris 50 years ago or before …

    There's always Tynant Spring water that has a very pretty deep blue bottle, and of course the new blue Budweiser Platinum beer bottles are nice, but small. There used to be a Blue Nunn German White Wine that had a nice blue wine bottle shape. Some Pinnacle Vodka bottles are made of an appealing light blue glass, and you can scrape off the plastic films off most bottles with a razor blade, just be careful!

    Several variants of reisling comes in blue bottles--most of which would be usable for this purpose. :-)

    Brilliant instructable and also everyones ideas about different effects. The waste is what I really want to comment on. The bottle bottoms can be laid within a square frame and epoxed together to for an old English cottage style window, like something out of Hansel and Gretal.
    Has any one any ideas for the tops??

    I've thought it'd be pretty cool to wire a TON of them as a kind of chandelier-- one small bulb or LED with a short lead into a single junction. Like a flower.
    Some people have talked about modifying this method-- post pics!

    That sounds nice! Even the cylindrical shape would mimic a candle. Wonder what a few of these necks would look like if they were threaded over solar lights in the garden, or even electric ones on a patio. It's not as if the heat will do anything to the glass. You'd have to do some designing, but it opens up a world of possibilities!
