Although there were many Scottish stoneware potteries producing stoneware bottles only four have been confirmed as having made sprigged jugs.
The four are in order of foundation
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. Click button for examples.
Founded about 1816 (O,H&H) closed 1930 (Scottish Pottery Society). Click button for examples.
The Dryles Pottery was a brick & tile works first mentioned in 1816. It was controlled by David Crowe between 1833 and 1856
Founded by Frederick Grosvenor at Bridgeton, Glasgow in 1869 and renamed The Eagle Pottry in 1885. Closed c1925. Click button for examples.
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.
H. Kennedy made snuff jars with the traditional sprigs derived from a Louis-Leopold Boilly (1761-1845) print. Click button below to see Boilly print.
