This is an English cobalt blue art glass vase, perhaps from the Bristol region. The maker is unknown. The date is circa 1880.
The vase is 8 1/8” high, 7 ½” wide at the belly and 5 5/8” wide at the mouth.
The shape is one of a large round foot, tapering into a bulbous belly – body, and with a wide neck. The glass is paneled, and the ridges are a darker blue and the panels are a lighter blue. The panels can be seen more clearly and felt in the interior of the vase. The rim is round. The pontil is a snap-off with a clear glass plug applied over the snap-off.
I have not ever seen a glass vase like this one, so it will be difficult for me to describe it. The middle and a band around the neck were treated with acid, to give it that whitish appearance. Where there are birds and leaves, the cobalt glass was not treated with acid. The outlines are in white enamel paint, but not thick enamel like how the French and Bohemian glassmakers decorated. Other colors were used to create the birds and seeds. The birds, leaves and seeds circle the body of the vase, and there is not a repeat of the same bird or plant. The entire bird scenery is outlined in a blue enamel paint. At the bottom, above this blue line, you will see darker blue, and that is an application of a blue color over the cobalt glass. You have to zoom in on the photos of the interior, so you can see what I mean. As I said, I’ve never seen an antique art glass vase decorated in this way, and this one was quite labor intensive with quality artisanship.
The bottom of the foot has a lot of scratches and age wear, along with a few pinprick nicks. The rim has one small pinprick nick and a tiny area of roughness that I show in close-up photos. There are quite a few of small air bubbles in the glass. There are no chips or cracks.
