This material, often consisting of phyllosilicates, has smaller particles than silts, forming microscopic crystals, but is often found with silts.
This material, often consisting of phyllosilicates, has smaller particles than silts, forming microscopic crystals, but is often found with silts. This group often contains significant amounts of water between its silicate sheets, which gives it its trademark property of plasticity, while exposure to heat can dry it out, leading to hardening.  Name this material which is often used in pottery and sculpture.
