Roman Seawater Concrete Holds the Secret to Cutting …
4/6/2013· Roman concrete produces a significantly different compound, with added aluminum and less silicon. The resulting calcium-aluminum-silie-hydrate (C-A-S-H) is an exceptionally stable binder. At ALS beamlines 18.104.22.168 and 22.214.171.124, x-ray spectroscopy showed that the specific way the aluminum substitutes for silicon in the C-A-S-H may be the key to the cohesion and stability of the seawater …

Peridot: The Healer''s Stone | Crystals: In-Depth
Peridot has been used as a Power Stone for centuries. Peridot fosters emotional balance, and helps us heal from past emotional wounds. It clears the pathway to the heart and heals damaged egos. Anger, jealousy, bitterness, and irritation are usually a result from wounded hearts (and sometimes, a wounded EGO). Peridot helps us move past the hurt, and understand our relationships. It adds
Desert Rose Rocks from SpiritRock Shop
Desert Roses are mineral formations that are found on the surface and are examples of the natural shaping forces of wind, water and pressure. Rosette crystal habit tends to occur in sandy arid conditions, such as the evaporation of a shallow salt basin.

Gypsum - Wikipedia
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including
