Established about 1800 at Garngadhill, in the north of Glasgow it moved to Rutherglen between 1872 and 1874. Trading as Murray & Co. it continued there until 1897, when it went into liquidation. Purchased by the jam maker Hartley to manufacture their stoneware jars it also continued offering its previous range of products and finally closed in 1929. Excavations on the Rutherglen site have recorded a huge amount of ceramic waste but, I believe, no sprigged jugs. It is likely that salt glazing was discontinued after the move to Rutherglen, I don't think the Garngadhill site has been excavated.

Port Dundas

Founded by Frederick Grosvenor at Bridgeton, Glasgow in 1869 and renamed The Eagle Pottery in 1885. Closed c1925.

Derek Askey mentions Portobello making jugs and jars with sprigged hunting and sporting scenes when owned by W. & C. Smith (pre 1840). If this is the case I have seen none illustrated. Fleming attributed to Portobello sprigged flasks now believed to have been made in Glasgow.
Buchan would appear to be the source of many weakly moulded jugs,probably made in more recent times.
