The Grainger porcelain works was started in 1801 by Thomas Grainger.The business had different names over the years as Grainger partnered with others: Grainger and Wood, Grainger and Lee.The characteristics of a coddler that are used to determine the type of coddler are the backstamp and the screw threads.In many cases, we may refer to a backstamp style by the type of coddler upon which it was seen.

Type 2A and Type 2B coddlers have a reference number, R #561564 in a box below the circle. This mark has been seen on a coddler with a silver lid. Type 3 backstamps consist of the characters C51 in a circle topped by a crown.Around the top of the circle is written ROYAL WORCESTER VITREOUS or just ROYAL WORCESTER.Under the circle is written MADE IN ENGLAND or just ENGLAND.According to KM, this would be an English registry mark, and if so, the design was registered in 1909 with the British Patent Office. The example shown has twenty dots, and so it's believed that the year of manufacture was 1911. Around the top of the circle are the words ROYAL WORCESTER. There are banners on either side of the circle in which the words CROWN and WARE appear.The backstamp on Type 3 coddlers is dull green in color.

However, two types of coddler, or two sub-types of coddler, are distinguished from one another by the combination of backstamp impression, color of the backstamp, method of application of the backstamp to the coddler, material and spacing of the screw threads, and other discernable differences in manufacturing process or visual characteristic, other than the pattern.
