Hello bat 20, could you possibly repost the smaller glass which was identified as Portieux. I've attached a photo of a basket I have which looks to be a similar pattern but on researching it I came up with the factory Matthew Turnbull, Cornhill Glassworks, Sunderland. They produced a similar pattern of alternate petals? and pyramids and also blue glass around 1900. I was thinking your glass might actually be by them. Nev.
