Clag (glue)
Clag is an Australian brand of glue made by Bostik.
Although a range of glue products are today marketed by Bostik under the Clag name, the most recognised product is "Clag Paste", which is most commonly sold in iconic red 150-gram bottles that have been relatively unchanged since at least the late 1970s.
History
Clag was first trademarked in 1898 by Joseph Angus, manufacturer, of 216 Nicholson Street, North Fitzroy, Melbourne. The National Archives of Australia holds the original trademark application - a digitised version is available online (see References). The exact composition of the original paste is unknown but is thought to have been starch-based.
