Recently, I had the privilege to handle an original Lalique bowl.
This bowl had a chip in the rim. Removing the chip would return the value of the bowl to the original state price. There was a bit of pressure to get the chip ground and polished out without further damaging the item.
As you can see, I managed it to the owner's satisfaction.
The delight of this bowl is the use of the thickness of the tinted glass to bring out the form of the figures. Where the glass is thicker the milky white shows more distinctly. The weight of the bowl indicates that it probably is made from leaded glass.
