Nope but I think you would want tempered glass at least for the shelves which I assume you would have to buy. We used tempered glass for the cab doors. Of course all of our windows are 1920s original single pane...

Glass is really easy to cut all you need is a place where you can break it where you won't care about the shards, a straight edge metal yard stick with a cork back or something that will help it grip to the glass, a thin bit of wood to help the glass break along the score and a good glass cutter to score the glass. The real issue isn't cutting the glass it's when the glass has been cut. The sides aren't flat. In stained-glass the lead just covers the edge of the glass so it doesn't matter that the glass edges are sharp. In your application you may need to smooth the sides out in which case you would also need a wet router so that you could soften out those edges.

As practigal alluded to, cutting the glass is the easy part (1/8" or 1/4" that is), it is the edge work that can get tricky. Shelves while not really needing to be tempered really should be a minimum of 3/8" thick if sizable. And once you get over 1/4" thick you are not going to be able to take of those edges at home properly. Also most all glass shops will not cut glass purchased by you elsewhere as there is no money in it for them and all the risk is thiers.

I cut my own plate glass shelves, used a belt sander to bevel the sharp edges of the cuts. If you let the sander dwell too long on any single spot, it can make a heat crack.

Cutting new glass is relatively easy but we don't anything more than double strength window glass. For thicker glass, I think it would be more practical to order it cut to size. When we had a large plate glass window to replace, we got a great price on the glass cut to size and did the rest of the work ourselves. Much of the full price quote was the transportation and fitting rather than the raw material. The real trick is cutting down old brittle salvaged glass - takes a bit of time but saves a bundle of money.

Our glass shop has said they would cut a large mirror for me. I don't know if they would do that for an unknown person but I am a frequent customer.

I would order a test piece and see how difficult the project will be and then make the decision. That approach will cost you slightly more but you will then know if your project is practical for your tools, skills and time availability

I am always trying to economize on projects, but this is something I wouldn't do. Some of the pieces won't break cleanly; you won't be able to get a nice, clear, polished edge (and sanding it to at least get it smooth and remove the razor edges to prevent people getting cut will produce silica dust, which is hazardous to breathe); and it should be tempered glass, which is a process involving a glass furnace that can only be done after cutting so you can't do it yourself.

I quoted with 4 glass shops originally and all of them said that tempered glass wasn't needed. They've all said that they use 1/4" and 1/8" glass.

These are for the upper bar cabinets and decorative mullion cabinets.

@linda I'll try that on a sample piece. My shelves are 16" x 20" so they're not too big.

I would definitely go to a glass shop for 3/8".

Sounds like a good option, and I'm glad they are tempered. You may have been told you don't need tempered, but it's stronger and of course safer in case of an unforeseen accident.
