Mounting A Glass Tabletop On Wood

02/11/2013


From original questioner:

Making several end tables in a modern contemporary style. Floating glass top, 1/2 in. thick, 24" x 18" over a wood base. The glass will be well-supported from underneath by the wood structure. No frame for the glass or anything.

Question is: what is best approach to "mount" the glass to the support to keep it from moving around or getting knocked off? Want to do this in the least visible / inconspicuous way possible. Small neoprene (?) or similar disks? Some kind of adhesive? Is the weight of the glass (I estimate it will be about 20 lbs.) just about enough to keep it from going anywhere?

First experience with glass topped table so any advice welcome.

I've seen photos of other contemporary furniture with glass tops and on many of them it looks like there's nothing at all between the wood and glass.

Thanks!

Joe,

The thin, clear cabinet door bumpers are what I have seen used.

The edge really needs a good finishing as the glass surface has to fit in exactly into the the surface created for it and the final joint clearance needs to be done properly sop as to give a cool finish to the furniture.

polyurethane bumpers are what you search for. Use thin square shapes, and you can also get dark colors if your wood is dark to blend in. Any glass shop will have them, or order on line. Amazon even has them.

Thanks for all the tips.

I spoke with a guy who does these kinds of a tables all the time (and very, very nice ones at that) and he places the glass directly on the wood supports, nothing in between.

That is what I've decided to do with these tables if I can. The clear plastic discs ('bumpons' I've learned they're called) will be a back-up option if the glass seems too easily moved.

Thanks again.

Of course, a lot depends on the actual design, but I have no problem putting glass on wood. I've used cork, bumpers, silicone, UV cured adhesive, and wood as the contact surface for glass; they all have their applications. I would not, however, rely on friction (wood or bumpers) alone to keep a piece of glass where it needs to be. Post your design, and you could get some better feedback.

you can use this compound that's called SUPER MEND it comes in two containers that you mix equal parts of each ingredient. be careful because it get real hot when starting to work. it dries white and you have to use it right when it is real hot because it sets up fast but it is real strong stuff that will not give, break, bend or anything.

When you lay glass on a desktop, the glass shop will give you vinyl discs to space it up a tinch. It's good not to have contact on broad surfaces, in case of bumps or trapped humidity. The finish can also stick to the glass over time.

It sounds like you are resting the glass on struts. I'd put something there to cushion it in case the base does not sit flat, or it's put on a warped floor.
