A Swiss Household Essential
Bülach preserving jars were once a familiar sight in Swiss homes, used to preserve fruit, vegetables, jams, and other seasonal produce. Manufactured by Glashütte Bülach in the canton of Zurich, these distinctive green glass jars became a trusted household item throughout Switzerland.
A Symbol of Swiss Innovation
The first Bülach preserving bottles were introduced in 1920, with improvements over the following decades making them easier to use and clean. Their characteristic green glass, wire clamp closure, and rubber sealing ring helped keep food fresh for long-term storage. In 1948, the Universal Bülach preserving jar was introduced with a wider opening, making it even more practical for preserving whole fruit and vegetables.
Preserving a Way of Life
Before freezers became common, preserving food was an important part of everyday life in Switzerland. Families carefully bottled the harvest to enjoy throughout the winter months. During the Second World War, Bülach jars became especially valuable, helping households store seasonal food when supplies were limited. Production continued until 1972, after which they were gradually replaced by modern freezing methods.
Today, Bülach preserving jars are admired as practical examples of Swiss design and craftsmanship, reflecting a time when preserving the harvest was an essential part of everyday life.
