It may have taken away a few days of realizing my food and dinner plans with a friend, but it didnât get my spirit. With a little advice from the parents and a bowl of not-so-chicken chicken soup, I am back to 100%, body, soul and taste buds alike. White Bean and Sourdough Bread Soup.
Honeycomb calcite is a most unusual and impressive form of calcite that has been found exclusively in one locale in the world: Utah in the U.S. Even though honeycomb calcite is a fairly new discovery, the stone is actually quite oldâ¦ 150 â 200 million years old.
Calcite is the only common non-silicate rock forming mineral, being instead calcium carbonate. It has two refractive indices causing a significant double refraction effect - when a clear calcite crystal is placed on an image, a double image is observed; See the sample below. Calcite will fizz when dilute hydrochloric acid is placed on it. It may be fluorescent, phosphorescent, thermoluminescent and triboluminescent (see fluorite for definitions of these properties). Calcite is one of the most ubiquitous minerals, being an important rock forming mineral in sedimentary environments. It is an essential component of limestones, and occurs in other sedimentary rocks. It also occurs in metamorphic and igneous rocks, and is common in hydrothermal environments. Calcite is a common vein filling mineral in many rock types.
