The bowl was often manipulated, whilst the hot glass was still malleable, into different shapes.  The late 19th century bowls came, not only as shown above, but square4, tricorn5,11, ruffled6 and flanged7.  In addition to the common colours produced at the time, the bowls also came in black, canary yellow, olive-green, rubine,4 aesthetic green11, flint, opal, malachite, turquoise, patent queen’s ware and blanc de lait1.

In the 1920’s Sowerby’s introduced new colours; rainbow lustre, ruby and sunglow, which were used in the production of the dolphin bowls.8  Although the original 1880’s moulds were used, the plunger had been reworked to impress a circular design into the interior of the bowl.9  This was most commonly used on the new carnival glass colours, rainbow and sunglow.  The original smooth plunger had the Sowerby peacock incorporated into the centre, so that when the bowl was formed the trademark was impressed into the centre of the interior of the bowl.

The 1927 pattern book shows the dolphin fruit bowl was available in three shapes; flanged, crimped and cupped, with an illustration showing the crimped edge.8  However carnival glass variants have been found in square and hexagonal.10

During the 1930’s the dolphin bowl evolved again.  The 1933 pattern book shows a flanged bowl which was available in green, powder blue, rosalin or amber.8  A frosted, matt finish, achieved by using acid, was utilised on the raised floral pattern and the dolphin feet.2  It was at this time the design was officially registered.

The further available pattern books and lists do not show the dolphin bowl in any format.8  It is unclear when the production of this bowl stopped.
