Earthenware manufacturer - originally at the Winton Pottery, just on the Hanley side of the border of the pottery towns of Hanley and Stoke, Stoke-on-Trent, England. The works were named after Winton Wood.

In 1900 the original Grimwade Bros became Grimwades Ltd - they expanded production significantly and within 10 years had purchased a number of existing companies to help with the growth. 

Winton Pottery Works was their original and largest factory and this name gave rise to their well-known "Winton Ware."
Winton Ware became one of their flagship lines. Their range grew to include fine tableware, commemorative pieces, and novelty items — including miniature ware and promotional ceramics.

By the 1920s-30s, they were producing art deco patterns as well, with more stylised geometrics and bright glazes.

Grimwades Royal Winton became well known for chintz ware — full-pattern, all-over floral transfer designs - notable Chintz patterns were "Summertime," "Hazel," and "Sweet Pea".

Later use of the 'Winton' name: 

In 1964 Grimwades Ltd was acquired by the Howard Pottery Group and the business traded as Royal Winton.

In 1995 the ownership of Royal Winton changed and the new owner reverted back to the original name of Grimwades Ltd although they continued to trade as 'Royal Winton'.

GRIMWADE, Leonard Lumsden (c. 1863-1931), pottery manufacturer, Stoke upon Trent.

Leonard Grimwade was born in Ipswich about 1863, the son of Richard Grimwade. He began his business life with his uncle as a dry salter in Ipswich. He came to the Potteries as a modeller but quickly moved to manufacturing. 

He was joined by his brother, Sydney, by 1886, and worked the Winton Pottery. The style became Grimwade's Ltd. in March 1900.

Leonard Grimwade went for a time to Australia but returned to the Potteries.

In association with Brittain's, of Cheddleton (the paper manufacturers), he devised a thin printing tissue with a detachable backing, known as 'Duplex' paper, which facilitated the handling of lithographic sheets. The invention helped to make the litho process commercially viable. 

He is also credited with installing the first continuous process kiln, in 1901. In this process, known as the Climax kiln, the ware was packed into iron cages on wheels. 

A serious fire at the Winton factory in 1916 led to Leonard Grimwade proposing that Stoke on Trent should have at least three motor fire engines. 

A Liberal free-trader Leonard Grimwade was elected to Stoke upon Trent council and was also appointed to the local magistrates' bench. He was secretary of the Potteries Association for the Promotion of Federation, founded in 1907, and published 160 favourable replies to a circular letter to leaders of trade and industry in his Book of Opinions. Questioned by counsel for Fenton during the passage of the federation bill through Parliament and asked where he lived Leonard Grimwade replied "I sleep in Wolstanton but I live in the Potteries". He unsuccessfully contested the parliamentary election in Hanley as a Liberal in 1918. He was a member of King Street, Newcastle, Congregational church. 

He modified his free-trade views to some extent during the First World War, by which time his five factories employed 1,000 people. In December 1917 he printed a message from the prime minister asking for economy in consumption of food on reduced sized butter dishes, milk jugs and plates, which sold at one shilling each.

He married twice and had two sons and two daughters. His first wife, Marion, was elcted to the Stoke Board of Guardians in 1897. He was killed in a road accident on 26 January 1931 and was buried in Hartshill cemetery.

Grimwades produced a range of nursery and children's ware 

mark introduced in the 1930s 

Rodolfo Eisler was an importer of quality ceramics, silver and homewares that were primarily made in England. His shop was based in Buenos Aires, Argentina. 

He imported ware from a number of North Staffordshire potteries including The Pearl Pottery and Newport Pottery (Clarice Cliff ware).

Grimwades marked some of their ware with the month/year of
manufacture - in this example the 7/29 is July 1929 

marks used on various items 
of the dinner service 

The term "chintz" itself originally referred to printed cotton fabrics with floral patterns that came from India in the 17th century, and the ceramic industry borrowed that name for the dense, all over floral patterns that they began to produce. 

In 1928 Grimwades began producing chintz patterns with "Margauerite" being the first. This was an immediate success and a number of chintz patterns were introduced in the 1930s. 

These tightly grouped, highly detailed and vibrant all over floral patterns were to become a milestone in the company's reputation for versatility and beauty.

With the exception of an moratorium on decorated ware in the Second World War period, production of chintz continued until the early 1960s, when it was discontinued due to the high production costs associated with this style of decoration. 

In 1995 the new owners (Grimwades trading as Royal Winton) recognised the value of the chintz pattern and reintroduced it in the form of collector's pieces. The year 1995 was incorporated into the backstamp of the new chintz to avoid confusion with previous production.

Introduced around 1928 Marguerite was the first of the Chintz patterns produced by Grimwades. 

The Marguerite pattern has a white background with a floral design of various upright and daisy like flowers. It is a more 'open' design then subsequent chintz patterns which were usually very densely patterned. 

Summertime
