Oval Convex Glass #900A

Free Shipping

We have been bending and fitting antique replica convex glass (also known as bubble glass or domed glass) since the early 1970’s, and we currently stock most antique sizes and shapes along with their modern equivalents. Although convex glass is most popular with our Vintage Collection of frames, our convex bubble glass will fit any frame we make. 

Measuring Convex Glass

Convex bubble glass is measured just like flat glass, measuring length and width directly across the glass (not around the bend of the glass). Convex glass generally has a depth of between 3/4" to 1" although deeper bends are possible. The most popular sizes often seem unusual such as the Oval 13 1/2" x 19 5/8". Many people are concerned that these odd sizes are no longer available or will require custom bending fees. However, we stock many of these unusual antique sizes, and most often no custom set up fees are required.

Although we stock over 50 standard sizes of convex glass, we also custom bend any size of convex bubble glass up to 22"x28". Each custom bend requires a paper tracing of the size required. The line you draw will be the line the glass is cut to. You will need to allow 3-4 weeks delivery after we receiving the tracing to produce your custom size convex glass.


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, round, or antique octagon. A large percentage of these frames were family portraits that were and then covered with convex glass. Today many attics and basements are home to these family heirlooms framed in antique frames and often broken convex bubble glass.

Victorian Frame Company has a long history of bending convex glass replacements for these images. Our glass bending started in the early 1970’s and today we continue to manufacture convex glass along with a unique collection of antique replica frames. See our Vintage Collection of frames.

Uses of Convex Glass

Most 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 a 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. Just as the antique replica frames and convex glass are available today, it is also possible to have your modern prints made into a convex portrait. For information on having convex pictures created please visit the Brogan-Bowen Company.

Deep Convex Glass or Acrylic Domes?

Convex glass normally has a bend of about 3/4" to 1”. If you are displaying an item that has more depth than a photo or canvas, then you may consider using our acrylic domes which fit all our frames and range in depth from 2.5" up to 7". To view our acrylic domes click here.

  4. Near Perfect Fit

    Posted by Unknown on 25th Sep 2017

    The oval convex glass was a great replacement for the broken glass from an antique photo frame. There was plenty of room in the frame for minor adjustment glass, but not too large or too small in any direction.

    The glass is clear and free from defects.

    Delivery was fast. Packaging was excellent; mostly recyclable with just the necessary amount of bubble rap

  5. Victorian Glass Saves the Day for 100 Yr old Picture

    Posted by Unknown on 22nd Sep 2017

    While helping hang pictures, a 100 Yr old family photo in oval frame curved glass picture slipped from my Granddaughter's hands and the glass shattered. Victorian Glass had the exact size curved glass in stock and promptly shipped one to me. They were the only source I could find. Thanks Victorian Glass. You saved the day!

    I needed a piece of bubble glass for an old picture frame. A little research and I came up with the Victorian Frame Company. Measured, ordered and installed - all very easy.

  9. exactly what was needed

    Posted by Judy Pedersen on 15th Jul 2017

    The oddball dimensions were a clue that I'd likely found the bubble glass to fit the antique oval frame with picture. It went into the frame beautifully and now a family heirloom has taken it's rightful place on the wall. We'd almost given up finding one but this fit the bill to perfection. Thanks SO much.

  10. came in perfect shape

    Posted by Unknown on 25th May 2017

    Right size, right shape, fit perfectly.
