Custom Bent Glass for antique crown glass door bubble outMay 24th, 2011 Posted in All Repair Projects, Antique Glass Repair, Bent Glass, bubble convex glass
Antique china cabinets in the late 1800’s and early 1900’s use to have very intricate designed wood mullions in the doors. They would install glass that bubbled out between the wood. This is called crown glass or bubble glass. Pennsylvania House Furniture also used this technique in there breakfronts. We made replacement glass for Pennsylvania House Furniture for many years . We custom make replacement glass for any antique cabinet doors. The curve in the glass is not simple radius .
I make a custom mold for each piece no two bent crown glass doors are the same.
In the very old pieces of furniture the glass was putty in place . They did not use wood stops to hold in the glass. They would use Portland cement in the putty . This makes the putty very hard and you have to grind it off to install the replacement curved glass.
The real work come matching the antique glazing that holds the glass in the wood door. First you tint the putty and install the glass. Then I use pitch to darken it more and give it the aged dirty look.
