Weekly Dose of Salt
Sel Gris: harvested from the bottom of tidal ponds off the coast of France, it is raked out after sinking
Also called celtic salt, gray salt
A natural salt
Sel Gris is harvested from the same salt pans as fleur de sel. The difference is that this salt is allowed contact with the bottom of the salt pans, which causes the salt's gray color. This salt is more moist (with 13% more moisture on average) and is courser than the delicate fleur de sel. Due to the high moisture, this salt does not draw the moisture away from food (what it is commonly applied to). The higher moisture does prevent this salt from drawing in as much psychic energy as other salts, but the energy retention is higher of the energies given to it outside of psychic energy in use of spell-craft.
The bottom of these salt pans are commonly lined with clay, tile, basalt, sand, or concrete. These linings keep the salt clean, and during harvest, there is care to prevent contamination. You may be able to find what type of lining is used in the pits your salt comes from by looking into the company that has produced your batch.
Below I give personal correspondences. I base these on not only chemical compositions, but more importantly, use. I believe when it comes to correspondences, associations are what drives your energy into the direction it goes. I base this off of how I understand correspondences to have traditionally worked.
Clay: A fine grain, natural soil containing clay minerals. Develops plasticity when wet, and becomes hard and brittle when dried or fired. The chemical composition breakdown would be long in list and correspondence, clay has an extensive history, and correspondence can depend on the type of clay and the method of use. Therefore, I am giving personal general correspondences for the category of clay. Magically, I believe clay is many in correspondence depending on the above factors. It can encapsulate transformation, destruction, will, immobility, binding, grounding, and of course earth (to name a few examples). When using clay for correspondence, consider the type of clay, the way you are using it, the state of matter it is in, and the end product of the clay you desire.
Tile: Tile can be made of various materials (which will affect your working if used). Tile also comes in many colors and patterns which will have the same variances. Magically, I consider tile to have general correspondence of barriers, both in a way of reflection and disallowing of adhesion.
Basalt: A fine grained rock formed from rapid cooling of low-viscosity lava that is rich in magnesium and iron, that is also exposed at/near the surface of a planet or moon. Basalt holds majority of volcanic rock on Earth, underlines most of the Earth's oceans, and can contain small amounts other minerals such as quartz. Basalt also holds majority of the surface of other celestial beings. For my personal magic purposes, basalt corresponds to grounding, courage, stability, support, and connection.
Sand: Sand is ground minerals, and can vary widely in composition, color, and type (ocean, desert, volcanic, pond, etc.). Therefore, I am giving correspondences to sand as a category, based on use instead of composition, though composition will affect your working and may be something to look into if you wish to practice pinpoint magic. For most, using general correspondences for the category will suffice. My personal correspondences for sand (depending on use) are foundations, interconnections, discomfort, insulation, grounding, the temporary, and the moment.
Concrete: Concrete is the most common building material today and is constantly being changed in composition, on top of there being many types of concrete. I suggest looking into the type of concrete you use as volcanic concrete will have different nuances to polymer concrete, for example. Concrete has high compressive strength, but low tensile strength. All concrete structures will crack to some extent due to gradual shrinkage and tension. Again, I am giving general correspondences for the category. My personal magic correspondences for concrete are compression, weight, stability, the constant, fate.
You may consider the location of harvest in your personal correspondences.
