 Since the kauri gum was found to mix more easily with linseed oil , at lower temperatures , than other resins , by the 1890s , 70 percent of all oil varnishes made in England used kauri gum . It was used to a limited extent in paints during the late 19th century , and from 1910 was used extensively in the manufacture of linoleum . From the 1930s , the market for gum dropped as synthetic alternatives were found , but there remained niche uses for the gum in jewellery and specialist high @-@ grade varnish for violins .
