Glue the wood to a piece of glass before you start working it.
A perfectly flat surface is necessary for carving on glass and placing components for pointed work onto stained glass windows.
But even if your surface is flat, it probably won’t be completely smooth, so you need to apply some filler to level out small bumps and dips in the substrate before applying any bonding substance.
When selecting a glue that will bond wood to glass, remember this: glues appropriate for stained glass are very different from those used in most other hobbies or craft activities aimed at woodworking. Stained-glass adhesives must not have an acidic breakdown product or ingredients that are harmful to the glass. Therefore, you must use a special adhesive that has been formulated just for this purpose and which will not harm the glass it is applied to.
For most stained glass work, epoxy adhesives are the glue of choice. My personal favorite is 3M Corporation’s T-881; it always does a great job and lasts a very long time.
Because you’re gluing wood to glass that may be clear or translucent white, applying the adhesive only on the parts where the two surfaces will come into contact is necessary. If you coat an entire surface with adhesive, the chances are good that the uncoated portions will stick together while you’re trying to position them for placement at their final location–and as soon as they start sticking, they won’t want to come apart again! I’ve seen this happen dozens of times when other people have tried using inappropriate adhesives.
After applying the glue to both surfaces, position them to be level and in line with each other. Then leave them alone until they’re sure of sticking, usually 24 hours or longer, depending on how much of a gap there is between pieces.
For stained-glass work involving multiple layers of glass bonded together, an epoxy called Araldite Rapid Cure is a good choice for adhesive. It’s handy when you need to bond several panels together all at once; it dries very fast (20 minutes) and has a pot life that extra hardener can extend by adding extra hardener from the tube if necessary. It also can bridge gaps between substrates up to 1/4″ (6mm).
For pointed work, an epoxy often used is Beacon 534. Both of these are powerful adhesives capable of holding together quite large pieces of glass, and they have been tested to be safe for use with the glass commonly found in stained-glass windows.
Special adhesives can do bonding wood to metal successfully by using a special adhesive formulated especially for this purpose. Rustoleum’s Zinsser Bullseye Weldbond works particularly well, but there are others on the market as well that will do the job if you can’t find it. This type of adhesive spreads easily over surfaces, dries slowly (24 hours +), and cleans up with water or acetone before it starts to harden too much. You can use it to hold cork or other wood materials onto metal, but its main use is to hold the glass (or sometimes ceramic tiles) onto metal frames.
DIY wood glue for attaching glass to ceramics is Mirak Major Tack. This type of adhesive will stick almost anything together; it’s available in several different formulas depending on the substrates you’re assembling and how much time there is before you must finish working with them.
Like some epoxies, this product contains an acid-based chemical that has a potential health risk if inhaled over a long period – so wear suitable breathing protection when using it!

If you’re gluing two pieces of wood together at right angles and want them to remain that way permanently, there are several adhesives you can use. One of the best is an epoxy called Devcon Shoulderless Epoxy. This adhesive does not need clamping to hold it together; all you have to do is spread it on the surfaces and wait for it to set up completely (24 hours or longer).
But carpenters often use what’s called “old-fashioned” glue. The yellowish glue has a bad reputation in most other activities but works well when applied with care, caution, and skill. While using this type of adhesive, it’s important to remember that you must not apply too much pressure on your clamps–or move them around too much during this process. The glue sets up very quickly (20-40 minutes), and you can damage the wood if you start moving things around.
Conclusion
Be sure to use these tips wisely and keep them in mind as we make our way through upcoming posts that will focus on gluing projects for stained glass, sculpture, furniture joinery, embellished picture frames, and other fun stuff!
