i have some glass sitting in my garage that i was able to get from work they were originally used for shelving the dimentions are 48"x16"x3/8" my question is i what to make a tank a little wider then 16", would i be able to rip two pieces of glass to 11" and use 3M 5200 silicone to bond the glass together and use it for the bottom of the tank?
the stand will be solid and have a plywood top for the tank to sit on so bowing wouldn't occur.
So you want to bond two pieces of glass together and have a joint on the bottom piece? What is the difference between that and having a crack on the bottom? I would want a solid piece of glass if it were me, especially since you are looking at a pretty good sized tank if you tried to make it 22" deep... IMO.
