On the subject of the moulds, Mark, this has just reminded me I've been meaning to mention to you that I think there may have been another size, apart from the tall bottles, the rectangular bottles and the short pots.
I've got a medium height bottle, with an odd, very thick cup-shaped rim, but it is rectangular in shape - the longest side is the same as the tall bottles, but the other side is shorter.
The bases of the small pots are ~ 7.5cm x 7.5cm
The bases of the tall bottles are ~ 10cm x 10cm.
This oddity is ~ 10cm x 8cm, and is 28cm tall.
(ps I emailed you recently, with a load of images and awkward questions, but I'm not sure I used a current address.... xxxx)
