I have a vase that is very much like Dave's and some of the others shown in various links. Dave's would seem to be a darker shade of blue than mine and mine seems to have a smaller base area than Dave's but other than that and slight difference in size (mine is 8 7/8 inch [22.5 cm] tall) it's the same - apart from having no signature inside the neck!
I have no idea who made these. I bought mine in the early 1990s in an antiques & collectables fair (southeast England). A few years later there were a couple in red (I think) in a London auction room described as "Stourbridge Satin Air Trap". Hmmm. They were
not "Air Trap" - just mould blown, as has been said. And, like mine, they did not have a "Satin" finish. When turned in the light, my vase shows glossy reflections in all parts, not a "sheen" as I would expect from a satin finish.
I would question whether lots of those found on the interweb are "satin finish".
As for the name of the pattern, maybe "Cut Velvet" is how it is described in the American collectibles arena and maybe that is also a real factory pattern name. I know not. I find it just as intriguing as the pattern name "diamond quilt" which seems to be applied to various non-pressed glass items, but appears to have its main use within pressed glass items (especially from Imperial). But even for the pressed glass items, the actual pattern seems to vary quite a lot.
So what is the truth about Dave's and my vase (and all those others)? It would be nice to know one day.
