Oval Convex glass is the most common shape of convex glass. We have been bending and fitting antique replica oval convex glass (also known as oval bubble glass or oval domed glass) since the early 1970s, and we currently stock most antique oval sizes along with their modern equivalents. Oval Convex Glass is available in these sizes:

Measuring Oval Convex Glass
Oval Convex bubble glass is measured just like oval flat glass, measuring length and width directly across the glass (not around the bend of the glass). Oval convex glass generally has a depth of between 3/4" to 1" although deeper bends are possible. The most popular oval sizes often seem unusual such as the Oval 13 1/2" x 19 5/8". Many people are concerned that these odd oval sizes are no longer available or will require custom bending fees. However, we stock many of these unusual antique oval sizes, and most often no custom set up fees are required.
Although we stock 15 standard sizes of oval convex glass, we also custom bend any size of oval convex bubble glass up to 20" x 24". Each custom bend requires a paper tracing of the size required. Please mail us this tracing with your name, and phone number. The line you draw will be the line the glass is cut to. Please allow 3-4 weeks delivery after we receive the tracing to produce your custom size convex glass.
History
Although oval picture frames make up less than 5% of all picture frames produced today, this has not always been the case. Over half of the picture frames produced in America by some the largest picture frame factories in the late 1800's up to about 1940 were oval picture frames, round picture frames, or antique octagon picture frames. A large percentage of these frames were used to frame family portraits with convex glass. Today many attics and basements are home to these family heirlooms framed in antique frames and often broken convex bubble glass.
OVALCREST has been bending convex glass replacements for these images since the early 1970’s and today we continue to manufacture convex glass along with a unique collection of antique replica frames.
Uses of Oval Convex Glass
Most oval convex glass is used to cover antique portraits in which the photographs themselves were also convex. We produce convex glass to fit our own antique replica frames, and also can supply an oval convex glass replacement to fit actual antique frames. We also regularly produce convex glass replacements to replace broken pieces in clocks, gauges and other instruments.
The Bending Process
Convex Glass is made by laying flat glass into frame molds and heating the glass to temperatures that allow the glass to slump. Longer heat creates a deeper bend. Most bends are between 3/4" and 1" deep.
