I recently built some cabinetry doors using the technique I saw in a recent issue for glass doors. The glass is held in with glazing compound tinted with color. It is taking forever to dry and I am wodering if I can hasten the process. It has been about three weeks and it is still a bit soft. I have tried a little heat but to no avail. Help Please. Thanks, Bob

I am assumming that you have used Dap 33 glazing compound.
It is mostly a mixture of white clay(kaolin) and linseed oil. The oil solidifies the mixture as it dries and is exposed to the air. The linseed actually polymerizes with the clay to give a long lasting way to seal glass to wooden sash.
In normal applications (window sash) the glazing is applied and allowed to "skin", or dry enough to allow a painters brush to apply paint to make a seal from the wood sash over the glazing ribbon and onto the glass surface by an 1/8".
Years will pass before the glazing truely becomes hard as set water putty.
So you can expect many weeks to pass before your putty ribbons firm up. Even then an errant sharp finger nail may pierce the glazing. I hope that the glazing rail is inside the cabinet to reduce possible damage.
I do not have a suggestion for accelerating the drying process.
If it really bothersome you may have to remove the glazing an replace it with a mecahnical retainer, glass bead moulding, or a clear vinyl keeper strip that is offered by some speciality companies.
If only we aged as slowly as it dries...........Iron Helix
Bob,
In my experience, glazing compound is a poor choice for cabinet doors, for the exact same problem you are having. Personally I dould remove the DAP and mill some moulding to use as glass stops. Although I do use glazing to bed the panes of glass. It is also easier to match the stain when using wooden stops. I use a pinner to install, and will be a lot less mess involved if you have to replace broken glass. Good luck.
