Historical information

Stoneware is a rather broad term for pottery or other ceramics that is fired at a relatively high temperature.  A modern technical definition is a vitreous or semi-vitreous ceramic made primarily from stoneware clay or non-refractory fire clay. Whether vitrified or not, it is non-porous, it may or may not be glazed. Historically, across the world, it has been developed after earthenware and before porcelain and has often been used for high-quality as well as utilitarian wares.
As a rough guide, modern earthen wares are normally fired in a kiln at temperatures in the range of about 1,000°C (1,830 °F) to 1,200 °C (2,190 °F); stoneware's at between about 1,100 °C (2,010 °F) to 1,300 °C (2,370 °F); and porcelains at between about 1,200 °C (2,190 °F) to 1,400 °C (2,550 °F).
Historically, reaching high temperatures was a long-lasting challenge, and temperatures somewhat below these were used for a long time. Earthenware can be fired effectively as low as 600°C, achievable in primitive pit firing, but 800 °C was more typical. Stoneware also needs certain types of clays, more specific than those able to make earthenware, but can be made from a much wider range than porcelain.
A domestic item used to store food products as glazing makes the container non-porous, often used for pickling. Or larger containers for kitchen flour. Items age is difficult to determine given the same techniques for making stoneware are in use today. Stoneware containers were made by many potteries in Australia and England. They were in common domestic use before plastics were invented around 1940 to store goods so this subject item is probably from around 1900 to the 1940s.

Significance

Item's significance is difficult to determine given it is not associated with a place, person, historic event, or manufacturer. Its significance lies with its use as a domestic object giving today a view into our social past.
