Precious travel hourglass in silver made of two openwork cylinders pivoting into one another and allowing the opening and closing of windows revealing the flask.
The outer part is made of silver filigree. The inner cylinder is formed of a solid silver sheet with partially erased hallmarks. Inside is a flask made of two cylindrical bulbs in slightly smoked « bubbled » glass and filled with a very fine lead sand of about 50 microns.
The bulbs are joined by wax covered with a beige fabric and bound over with a silvery thread.
