The cobweb-like pattern of cracks is called "Cracquelée". The creation oft he glass an art! After being blown into the mould, the glass is briefly immersed in warm water. Small cracks appear on the surface due to the temperature shock. Then the Craclet-glass is heated again to close the surface. A brilliant and unmistakable structure is created. As soon as you light a tea light in it, you will experience a wonderful play of light. Just as beautiful in the living and dining room as on the balcony. Alternatively, equip the lanterns with flowers and creatively make a small vase out of them.
