55x30 sounds like a dream tank!! Seriously. I'm not sure if I would use the piece as it is though with the holes (true they could easily be covered by a small piece of glass and some silicone) and most notably the score line... I'm not sure how that would affect the tempered glass's strength or it's probability for failure.

I'm excited to break some sh!t.

Honestly that sounds like it would be really fun to do... Look for the Youtube video.

I think the people that put it out were hoping someone would pick it up 'cause I don't think the garbage truck would take it away so easily... Mine around here are pretty strict with lengths and weights. This piece of glass probably exceeds both limits.

xmas_one Do a plywood tank with the 36" piece.

TheDrake try this to see if it's tempered
03-23-2013 03:43 PM
genocdex im saying to use the holes. cut off the right most 2, they are too close to the end. but then the remaining 2 you can work into the tank for a canister filter intake and output. kinda like how many people like to do sw tanks. just have to make them a bit bigger (maybe) and buy the bulk head plumbing...

ajmckay Hmm... I'm not getting 18x15 to fit (without using the scored piece or using the holes)
03-22-2013 10:27 PM
genocdex you could do a 18x18x15" using 2 holes as a sump style of filter or just the in and out for a canister filter.....
they might be too small, might need to increase them a bit. but a that should be at least 25g tank for you, using the 1/2 for bottom....

thelub Nice find! Free glass is always nice

I don't think it is possible to cut tempered glass at all. They temper it once its the size that is needed. It is hard to find float glass any more. Most glass that is used in homes is tempered because it is a lot less dangerous than float.

If you have some polarized glasses, look at the back window of a car and compare it to the glass. If they look the same its tempered.

If its not tempered, the score mark will prove difficult to cut if your new cut line intersects that one. Most of the time glass will break on an existing score line.

If it is tempered, you have yourself a new bottom for a 55x30 tank

before you even think about cutting it, try to figure out if it's tempered. Easiest (but least likely to provide any info) would be to look over it for any etchings/markings stating it's tempered.

Failing that, I'd look along the edges for that characteristic conchoidal fracturing. Finding some wouldn't necessarily mean it's not tempered, but it would be some evidence towards that.

There is a way you can check for whether glass is tempered or not using polarized lenses (you can get these from the 3D glasses in movies). I'm not sure on the specifics for checking tempered, but play with the lenses alone first, then with a piece of non-tempered glass, and then your new piece. Stack the lenses on top of each other, and look through both of them, and rotate just one of the lenses while you do this. There should be a point where they are almost completely black, and then it should get brightest about ~90 degrees from that arrangement.
Good idea - it probably was a shower door. The top holes to hang it and the middle holes for the handle. I'm not sure what the big score mark is though.

Also good point about it possibly being tempered. If it were a shower door I'm sure it would be tempered, right? I'll check with some polarized lenses to see if it's tempered...

If it is tempered I can cut it with a diamond wet saw, correct? I have one of those I use to cut ceramic tile.

As for uses, I think a 14" cube would be pretty cool. I've never had a cube but I've always wanted one. So far I've figured out how to cut the glass such that 3 pieces would have a polished & beveled top edge. I'll see if I can work in a 4th, but I'm thinking I may have to polish that edge up myself. How cool would it be to have a 14" cube for free

Hoppy It isn't enough glass to make a 40B, as far as I can see. The score mark and the holes greatly reduce your options, even if you use the piece of .5 inch glass for the bottom. You might get a 16 inch high, 32 inch long tank made, about a 40 gallon, but with odd dimensions. I didn't check to see if the glass thickness is enough for that size tank. I don't think it is.

assasin6547 Nice find! The other piece of glass is the size of the bottom of a 40b, you should make a 40 gallon breeder. Just cut out sides for the tank.
