This type of Mortar and Pestle was used for gold samples. A common source is the collecting and processing of flakes of elemental gold that have flaked away from a surface during the process of gilding it. Once the flakes of leftover gold (called skewings) have been gathered, they are mixed with a small amount of honey and ground together with a mortar and pestle until they become a powder. The honey is then removed by placing this mixture in a bath of hot water, leaving the gold flakes to collect at the bottom. The upper layer of water is poured off and the process is repeated several times, the last few with deionized water. Following the final rinse, the flakes are left to dry. Once the water has nearly evaporated, a drop of concentrated gum arabic is added and mixed into the flakes, creating a basic paint with gold flakes/ dust as pigment. The paint may be applied to a surface using either a brush or the tip of a finger, and can be reactivated by only the moisture in an exhaled breath of air. This size is atleast 7x 7 and 9" tall. Most, but not all morters were made of caste iron and then painted for resale, this one inperticular was created and for antiques and rustic looks.
