John Philip Elers and his brother David Elers were Dutch silversmiths who came to England in the 1680s and turned into potters. The Elers brothers were important innovators in English pottery, bringing redware or unglazed stoneware to Staffordshire pottery. Arguably they were the first producers of "fine pottery" in North Staffordshire, and although their own operations were not financially successful, they seem to have had a considerable influence on the following generation, who led the explosive growth of the industry in the 18th century.

Redware as a single word is a term for at least two types of pottery of the last few centuries, in Europe and North America. Red ware as two words is a term used for pottery, mostly by archaeologists, found in a very wide range of places. However, these distinct usages are not always adhered to, especially when referring to the many different types of pre-colonial red wares in the Americas, which may be called "redware".
