Convex glass is essentially glass that rises up in the center, creating a dome like effect on whatever its encases. Picture a scaled up version of an eyeglass.
Other (albeit incorrect) names you might have come across for this material include curved, bubble or domed glass: misnomers for obvious reasons. While these all have a curved surface like convex glass they are in fact produced with a different method and often used for different purposes.
Curved glass is rounded at two ends, but does not create a full seal around all edges. This was commonly used for china cabinet doors.
While convex glass appears to look quite a lot like a bubble, Bubble glass actually means that the glass was manufactured by a process called drawn glass, which creates “seeds” or elongated bubbles in the glass. Domed glass is another would-be convex glass.
Dome glass is typically used for clocks and has a more pronounced or raised center than typical domed glass.
Another antique that commonly used convex glass was in the faces of instruments and clocks. This gilt wood barometer was restored, requiring the replacement of its convex glass panel.
Although convex glass is antique in its appearance, it is still produced today by select fabricators. Not only is this helpful when replacement glass is needed for an antique, but also in offering an interesting and unique effect when framing even contemporary projects.
The curvature of the surface creates an interested effect with light and sense of depth. Convex glass is especially useful in framing three-dimensional or raised artworks, where more space is required to protect the work.
