Ravenhead Kilner Jar Value Guide

The Ravenhead Kilner Jar is a quintessential piece of 1970s British domestic history, manufactured in St Helens after Ravenhead acquired the rights to John Kilner's 1840s invention. These heavy-duty glass canisters are highly collectible for their robust construction and their legacy as the primary tool for UK home preserving and pickling.

What affects the value of Ravenhead Kilner Jar?

• Condition of the wire-bail mechanism, specifically looking for signs of rust or loss of tension.
• The presence and elasticity of the original orange rubber seal, though replacements are common.
• Clarity of the glass, as cloudiness or 'glass sickness' from improper storage can decrease value.
• Completeness of the unit, ensuring no chips are present on the rim where the seal must sit flush.

How to Identify Ravenhead Kilner Jar?

• Look for the distinct 'Kilner' branding embossed directly into the clear glass body.
• Verify the presence of the original heavy-gauge steel wire-bail lever mechanism.
• Check for the signature orange rubber gasket seal, which is characteristic of the Ravenhead era production.
• Confirm the glass has the substantial weight and thickness associated with 1970-1980 English manufacturing.
