This old bottle is unusual for a few reasons.
It is what is known as a Codd Bottle. In 1872, British soft drink maker Hiram Codd of Camberwell, London, designed and patented a bottle designed specifically for carbonated drinks. The bottle was designed and manufactured with thick glass to withstand internal pressure, and a chamber to enclose a marble and a rubber washer in the neck. The bottles are filled upside down, and pressure of the gas in the bottle forced the marble against the washer, sealing in the carbonation. The bottle is pinched into a special shape to provide a chamber into which the marble is pushed to open the bottle. This prevents the marble from blocking the neck as the drink is poured.
Made for John Starkey, Sydney it features their trade mark design of a key and a star! The purple colour comes from the manganese used in the glass which changes to purple when exposed to UV light. This ingredient was removed from glass production around 100years ago.
An interesting piece to add to the collection.
