I'm having trouble finding this shape in Geoff. Timberlake's book. Nazeing appear to have made few items with a good 'bowl-shaped' symmetrically curved side profile - although in fact this one looks almost irregular and not a real curve. For this reason I'd suggest it's not a match for the bowl in Nick's link.
The factory did produce a couple of designs under the heading of 'Sundry Art Glass Bowls and Dishes' which are very 'bowl-shaped', but those have side profiles showing greater curves than this piece.
My opinion would also be that if this doesn't show a small ground/polished depression on the underside of the foot, then that might also discount Nazeing.
Most of Nazeing's colours are quite variable - with bluey-greens and pale and darker versions of green, so this may be the least helpful feature - green was possibly the most common colour from Nazeing.
Of all the makers who dabbled in bubbled glass from around that period, Nazeing is possibly the most likely factory to find - sometimes quite common at antiques fairs - which raises the chances of this being from them, but I'm still having trouble with the shape.
The reason for mentioning Cluthra was because that product, apparently, was given a very heavy and thick clear casing - but since I've never knowingly seen a piece then regret can't comment further.
As you'd imagine, we've discussed Nazeing's glass and its bubbles to death on past occasions - use the Board's search and you find acres to read.
