flame test | Infoplease
flame test, test used in the identifiion of certain metals. It is based on the observation that light emitted by any element gives a unique spectrum when passed through a spectroscope. When a salt of the metal is introduced into a Bunsen burner flame, the metallic ion produces characteristic color in the flame.
Alkaline earth metal — Wikipedia Republished // WIKI 2
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.

Mechanisms Retardancy suppression -A
For example, metal ions from color pig-ments or seemingly inert filler such as calcium carbonate may lead to the formation of stable metal halides, rendering the halogen unavail-able for reaction with antimony oxide. The result is that neither the halogen or the
4 Ways to Make Colored Fire - wikiHow
8/8/2020· How to Make Colored Fire. Most fireplace fires or campfires produce yellow and orange flames because firewood contains salts. By adding other chemicals, you can change the color of the flames to suit a special occasion or just to be
US6387300B1 - Method for treating calcium borate ores …
Calcium is believed to act as a fixative agent in this matrix to dramatically increase the resistance of the substrate to the leaching out of the boron compounds. Calcium salts obtained from the reaction between the calcium borate ore and acetic acid, and the
Chemistry of Fireworks Colors | Munsell Color System; …
How does a pyrotechnician, a scientist, translate chemicals into a fireworks art display for the viewer''s enjoyment? To answer this question, we not only have to know how the elements and chemicals all around us can be manipulated to produce light and color, but we also need to know how the observer, us hule humans, SEE what we think of as "color."
