The origins of glass-making are shrouded in mystery. In many cultures, it was a highly-coveted secret passed down from master to apprentice and sharing the technique was punishable by death! One of the earliest forms of glass making, core forming, is traced back to ancient Greece. This process shaped liquid glass around a solid object to create a hollow center. Once it was cool, the core was removed to unveil flasks which were used to store perfumed oil. Our ancient flask puzzle challenges you to remove the stick and unveil the secret of Greece’s true genius.
