About this design
Blue & White Swirls — a descriptive rather than an official name — was among several early experiments that did not go into general production. The blue colour tends to be lighter than Seaward, which was produced at about the same time. Examples with a coachbolt pontil mark (indicating mid to late 1973) and with a flame pontil mark (indicating 1974) are known. Blue & White Swirls is rarer than Seaward; a few come up for sale each year indicating that although they are scarce they are not as scarce as some other experimental designs.
This magnificent charger is 42 cm in diameter. It has the earliest form of flame pontil mark used in 1974. Image courtesy of J.C.C. Glass.

Verdala bowl, 17 cm diameter, 5 cm high. It has a coachbolt prunt, indicating 1973. You will notice a crack just at the place where the coachbolt is attached. This is a manufacturing problem rather than damage. This dish is very similar to one illustrated in Mark Hill's book  on page 73.
