fired at a temperature between 1200 and 1400 degrees centigrade
Stoneware pottery has been around since Medieval times, much of it originally coming from Germany.
It is fired at a temperature between 1200 and 1400 degrees centigrade which makes it extremely hard wearing and waterproof.
It was very popular in the Victorian period and was used in a variety of ways from storage jars to ink wells, ginger beer bottles to hot water bottles.
Salt was thrown into the kiln during the firing process to give it its shiny, glazed appearance.
Denby has been producing salt-glazed pottery at its factory in Derbyshire since 1809. In that year William Bourne, a local entrepreneur noticed the quality of the local clay, and entrusted the running of the business to his son Joseph Bourne.
