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. Australian schools commonly request that parents purchase Clag paste for their children as part of the stationery lists that are circulated before each school year. The main reason for this is Clag's reputation for safety and ease of use. The bottle includes a brush recessed into the lid that children find relatively easy to handle, and the packaging does not contain any small components that children might swallow. The main ingredient of Clag is wheat starch dissolved in a water base, meaning that children can safely swallow the glue without incident It feels cold to touch and when applied to paper, it sometimes alters the colour of what is on it and causes paper to warp, owing to the high water content of the glue.
