thanks for the additional worry Ivo
the colour of your images does certainly match my grapefruit dish, although I don't have a problem with attribution for my dish since it most definitely carries the WALSH backstamp. However, bubbly glass, similar to 'Pompeian' does seem to have been produced quite commonly in the first three or four decades of the C20 by a number of factories (and may have been produced in much more recent times - but we're speaking here of pieces that are believed to be 'period').
Obviously, the thicker the glass, then presumably the darker the appearance of the glass (for a given colour) - and as some of these vases are quite thick walled, then they will look a darker shade.
JOK's vase appears to have a good quality pontil depression, and if he says the colour matches Reynolds, then he may be on safe ground in saying Pompeian.
Unfortunately, now I look more at my vase, it appears a bit too dark, and the absence of a pontil depression (it seems to have a flattened base with a hint of where the pontil was snapped), may well mean it's not Pompeian. I know almost nothing about making comparisons of this type of product, although I see many in antiques venues - so will play safe and say mine is of unknown provenance for the time being.
Pompeian is possibly the most common of the 'bubbled' glass, and it seems to have become a habit for us to say of any bubbled glass that it's from Walsh - saves having to consider the other makers.
I no longer collect this bubbled glass, it's too much like hard work to id - I picked up this small dish only because it was less than Sterling £1.00, and came with some other interesting old bits.
Yes, I know this is too long winded
