An early French iron coffee grinder known as the “Sablier” (hourglass) model due to its characteristic shape. Complete with a mechanism for fixing it to a tabletop, the very simple design allows the coffee beans to be introduced into the top portion through the hinged lid. The ground coffee, collected in the base, is retrieved by unscrewing the lower part. The handle is removable.
Dating from the end of the 1700s these models are similar to early spice grinders in their design. Examples like this one, with all of the original parts, are quite rare.
