Weck glass jars are made with thick glass to withstand repetitive boiling, sterilising and processing.

They are of such high quality they can even be used for baking making them the most versatile jar around. The J. Weck preserving company was founded at the beginning of the last century in Oflingen, Germany and their glass is still manufactured there today.
