POG, PAPP, OR EDINBANE?

Just to make matters even more confusing I've just come across Pottery Studio, a U.S. manufacturer, which may have a similar ep mark, but their pots are moulded so shouldn't be too difficult spot.

Pog Crafts:




Edinbane Pottery:




This mystery EP or GP. Evelyn Papp says it's not her mark

IMO Pog is easy to spot, the pink and white, blue and white and green and white variants of the marbled pots are common.

The one at https://www.20thcenturyforum.com/t6073-i-think-this-is-crich-confirmation-please#111498 is typical of the larger pots, single (grey) body glaze with a contrasting swirl of colour often with one or more ribs.

Pog is one of the most common studios I see at car boots.

In terms of Edinbane and Papp I really don't know, but I suspect both are more 'rustic' than Pog.
