At first, this rounded marking was thinner and made in celluloid, a species of an acrylic predecessor, which was used until the mid-40s, when it was replaced by high-quality acrylic. Because of its appearance, it was defended for years and by many, that the point was made in ivory. However, that is a widespread legend that lasted for years, as evidenced by the information and tests executed in the Pipes Magazine Forum, in a post called "Dunhill White Spot Drama".

'''Note:''' All pipes come with a costly fitted black ebonite (is generically known as hard rubber and is obtained by vulcanizing natural rubber for prolonged periods. Ebonite may contain from 25% to 80% sulfur and linseed oil. The material has also been called vulcanite, although that name formally refers to the mineral vulcanite). | |||

This version of spot appears only on the white mouthpieces, for an obvious reason. The stem is made from Erinoid (again, it's not made from ivory, as many believe) and the White Spot stands out with a delicate black ring. Into it is inserted a vulcanite tenon which in turn pushes into the shank's mortice. We have made contact with the Dunhill's factory and received the following answer: | This version of the spot appears only on the white mouthpieces, for an obvious reason.

<blockquote><q>It would be difficult to imagine a life without plastic. The first plastic was cellulose nitrate developed in the mid-19th Century, which was popular for co||ars and cuffs. The second was Casein hardened with formaldehyde and patented in Britain in 1911. Casein plastic was made under the trade name "Erinoid" at Lightpill Mills in Stroud for about 70 years from 1912. Unlike the later plastics such as Bakelite, Casein plastic could be dyed in many bright colours. It could withstand the rigours of washing and ironing, dry cleaning solvents etc and became popular for buttons and other household goods. It was eventually replaced by oil-based plastics for most users but is still made today on a small scale for high-quality goods.</q></blockquote> | <blockquote><q>It would be difficult to imagine a life without plastic.

'''Note''': All the stems were made by hand until 1976. They have since been machine made due to labor costs.
