When trovants absorb the rain's minerals, the minerals come in contact with the chemicals already present in the stone, causing a pressure reaction that makes the rocks grow in girth. It's not something you can see happening. Researchers say the deposition rate for trovants is roughly 1.5 to 2 inches (4 to 5 centimeters) every 1,000 years.2 thg 10, 2017 ...

It’s a very protective stone that provides both grounding and protection of your physical, emotional, mental, and spiritual bodies. Septarian is the stone that you should use when you want to regulate your physical, emotional, mental and spiritual prowess.Prenatal. Dental development begins at about three weeks of gestation. By six weeks of gestation the tips or cusps of the primary teeth appear. By the fourth month the hard tissues (the enamel and dentin) of the primary teeth have begun to form. The enamel crowns of most primary teeth are fully formed by eight months of gestation.A concretion is a clearly bound body of rock within generally softer enclosing sediments of the same composition. The term comes from the Middle English concret, itself derived from the Latin concrescere, meaning to grow together or harden. Concretions form by the selective precipitation from ground water of dissolved minerals, most commonly ...concretion. 1. Roughly spherical or ellipsoidal body, produced as a result of local early cementation within a sediment. It is often found with a fossil as a ‘nucleus’. The size ranges from approximately 1mm to more than 1 m, and concretions are generally monomineralic. 2.The formula for concrete mix is one part cement, two parts sand and three parts gravel or crushed stone. If hand mixing, it’s inadvisable to exceed a water to cement ratio of 0.55, which translates to 55 pounds of water for every 100 pounds...The material has good groutability and a concretion stone ratio which is greater than 99.6%. The coefficient of permeability of 28-day concretion body is 0.53 × 10-8-1.86 × 10-8 cm/s and the compressive strength is 0.64-1.04 MPa. The slurry has good adsorption and retardation properties.The formula for concrete mix is one part cement, two parts sand and three parts gravel or crushed stone.

When a character is first inflicted with the Stone status, they are still able to move, and being attacked does not cancel the effect - note that during this time they can be effected by Lex Aeterna, and cannot attack or use skills but still able to use items.

Synonym (s): stone (1) . Septarian or Lightning Stone is a concretion of hard, compact mass of matter formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. Concretions are often ovoid or spherical in shape, although irregular shapes also occur. The word 'concretion' is derived from the Latin con ...
