Flow Blue Sugar Bowl Value Guide

This mid-19th century Flow Blue sugar bowl is a prime example of the intentional 'flow' effect created by vaporized chloride in Staffordshire kilns. Its ethereal landscape pattern and durable ironstone body make it a quintessential piece for Victorian-era ceramic collectors.

What affects the value of Flow Blue Sugar Bowl?

• The intensity and evenness of the cobalt blue 'flow' across the white ceramic surface.
• The presence of the original matching lid, which significantly increases the $100 base value.
• Overall condition, specifically the absence of chips, cracks, or heavy tea staining on the ironstone.
• The clarity and detail of the specific landscape pattern used in the transfer process.

How to Identify Flow Blue Sugar Bowl?

• Look for the characteristic blurred or 'bleeding' cobalt blue edges where the pigment has run into the white glaze.
• Check for a heavy ironstone or ceramic weight typical of United Kingdom manufacturing between 1840 and 1860.
• Examine the base for Staffordshire maker marks or pattern names common to the early Victorian era.
• Verify the presence of a landscape or floral transferware design under the glaze.

History of Flow Blue Sugar Bowl

Flow Blue pottery originated in the Staffordshire region of England in the 1820s. The distinctive 'flow' effect, where the cobalt blue pigment intentionally blurred or ran during firing, was initially an accident in the pottery kilns. However, consumers quickly embraced this soft, ethereal look, leading potters to deliberately create the 'flow' by introducing a vaporized chloride of lime or ammonia into the kiln. This sugar bowl, with its classic landscape pattern, exemplifies the popular designs of the mid-19th century.
