Made of thin layers of wood glued together under heat and pressure, plywood sheets are durable, yet lightweight. The direction of the wood grain alternates with each layer— known as opposing grain— making these sheets strong enough for building ramps and shelves or repairing holes in floors and ceilings. For load-bearing applications, use 3 ...

Muscovite can assist in preventing the symptoms of rapid psychic awakening, including headaches, dizziness, vertigo, bad dreams, sleep imbalances and an inability to turn off the psychic flow of information. It is balancing for the brain and can be used to help alleviate other types of headaches, migraines and brain imbalances.

This clay is considered "self-tempered" because the right ratio of mica and sand is present in the clay pits. Cleaning clay is a multi-day process that begins with soaking the dry earth so that the clay can go into solution. I fill five-gallon buckets with water and raw earth and mix them by hand as the clay starts to hydrate.
