• Ellgreave Pottery was established by Henry Wood in 1921 and it operated as an associate company of Wood & Sons Ltd. 

• As well as general tableware, figurines, vases and the like, Ellgreave became an important producer of teapots.

• After the Second World War it introduced a range of insulated teapots / coffee pots. Marks included the company name and for the insulated ware the trade name 'HEATMASTER' 

• Ellgreave produced this insulated ware for a number of retalers and under a number of trade names - Bursley Manufacturing Co. "Heatmaster," Kosy Kraft Ltd. A.E. Medway & Co Ltd. "Mirabelle," "Regal," "Regency," "Teamaster"

• The vast majority of insulated ware was produced by Ellgreave, occasionally one appears which has the associate company Wood & Sons mark - this is assumed to have been produced by Wood to meet production needs. 

• In 1967 the company was put into voluntary liquidation, along with a couple of other Wood companies. Production moved to the recently modernised Trent and New Wharf Pottery of Wood  & Sons where the name Ellgreave continued to be used. 

• Uninsulated tea set ware was produced with the Heatmaster / Ellgreave name, other items such as bottle covers, beer tankards. 

• A range of oven-to-table ware was introduced by Wood & Sons under the trade name Heatmaster (although this ware was not insulated)
