About Weck glass:

• Weck was founded in Germany in 1900 and is one of the best-known glassworks in Germany. They produce glass jars for both commercial and home use.
• Weck jars are technically known as soda-lime jars. They consist of ~70% quartz sand, 10% lime, 13% soda, and small amounts of dolomite (making it less sensitive to temperature fluctuations), feldspar and sodium sulphate (which helps to prevent the formation of bubbles). Recycled glass is a major component.
