Ornamental stone (mainly granite, marble, and similar) is a common material used in construction for the decoration of building surfaces. Before they can be used directly, these ornamental stones usually need to undergo the necessary processing, cutting, grinding, and polishing, which produces a large amount of waste stone powder.Grinding stones were used to shape bone tools by abrasion, and to prepare cutting edges on ground-edge stone axes. In an interesting case of lateral recycling, a woman mortally wounded King Abimelech during an Old Testament battle by climbing a tower and dropping a grinding stone on his head (Judges 9:53).3D models of Grinding Stones Museum of Stone Tools
All abrasives, coated and bonded, should be stored in the following conditions: Dry and frost-free. Kept away from cold and damp. Not be exposed to high-temperature variations or direct sunlight. Within a temperature range of 18°C and 26°C. The ideal relative humidity is 45% excessively dry or humid storage may incur deformation.
