Very interesting item. Can you see joint marks near the marie? If so, how many? If no joint marks are present, this was likely pressed in a shell mould that gets flipped 180 degrees (after the glass sets up) so that the "catching out boy" can get it placed on a wide paddle. Then, it's stuck up on a large diameter punty rod with a flat head (the diameter of the head would be the same size as the area that is now seen as ground and polished). Once it's stuck up, it's reheated, iridized with a spray of metallic salts, and then taken to a skilled finisher to be cupped (hence, the stretch glass look that happens when an item is iridized BEFORE it's finished to its final shape). Then, it's cracked off the punty rod and taken to the lehr. Once annealed, that bottom area can be ground and polished. Fenton made a lot of plates this way in the 1920s-30s. I hesitate to speculate as to a maker, but it could be someone like Pairpoint or Durand in the USA, although I suspect its origin will turn out to be European.

Thank you for this wonderful, clear and very interesting explanation of the process, Mr. Measell!
Cheers, Sue (M)

And there WOULD have been peace on earth.

Thankyou JSMeasell for taking the time to give your very detailed and clear description, very much appreciated :D I've looked closely at this large bowl and to me, it appears to be made from one single block of glass as I can't see any indications of joint marks near the marie, so your option of pressing in a shell mould would fit :)) and thanks to everyone else for your help and advice too, It's taught me a lot :)

The bowl would be made from one piece (gob) of glass. The seams would be in the two-part mould and would cause lines on the glass. You only join handles, feet and decorative bits; you don't makes items in two halves and join them (at least not in pressed glass).
