I'd been chasing an example of this Thomas Webb cameo vase for a while but kept falling short. I was finally able to grab this one a couple of weeks back. The thing that I love most about it is the three color combination of citron, red and white, as opposed to the more common two-color cameo vase.
For those of you who aren't familiar with cameo glass, it's an interesting process. First, as in my case, a blob of citron molten glass is submerged in molten red glass followed by opaque white resulting in three separate layers. After blowing the glass into the desired shape and cooled, its ready to be worked.
The next step, is to mask off the pattern of the desired decoration. This is done by using heavy vinyl, bees wax or some other acid resistant material.
The vase is then etched down to the inner layer leaving behind the design outline in white relief. It can be etched in several ways - by submerging the glass in hydrofluoric acid, sandblasting or carving. The remaining white relief is finely detailed using grinding wheels, drills and carving.
