Azurite is used occasionally as beads and as jewelry, and also as an ornamental stone. [21] However, its softness and tendency to lose its deep blue color as it weathers leaves it with fewer uses. [22] Heating destroys azurite easily, so all mounting of azurite specimens must be done at room temperature.
Artemisia filifolia, known by common names including sand sagebrush, sand sage and sandhill sage, is a species of flowering plant in the aster family. [2] It is native to North America , where it occurs from Nevada east to South Dakota and from there south to Arizona , Chihuahua , and Texas .
Azurite is a basic compound that is coordinated with copper. [1] Azurite was popular due to its stability in various light and atmospheric conditions, making it easy to store. [1] Although azurite is permanent in oil and tempura paint, it is darkened when exposed to sulfur; this can be seen in mural paintings that use azurite.
Haüyne or prismatic azure spar is a transparent or translucent mineral, similar to lazurite, in composition sodium and calcium aluminosilicate with the ideal formula (Na,Ca) 4-8 Al 6 Si 6 (O,S) 24 (SO 4,Cl) 1-2 having a blue or blue color, sometimes with a greenish tint, [5] was also known among the azure spars.
The sand leek is a perennial plant with an egg-shaped bulb. The plant produces two to five unstalked leaves, the bases of which are sheath-like. Each leaf blade is linear, 7–20 millimetres (1 ⁄ 4 – 3 ⁄ 4 in) wide, [10] flat with a slight keel, an entire margin and parallel veins. The edges of the leaf and the central vein are rough to ...
Verdigris or Vert-de-Gris, is a blue-green, copper-based pigment. Its name comes from the natural pigments that form a patina on copper, bronze, and brass as it ages. [2] The most famous example is the green patina that formed on the Statue of Liberty in New York Harbor.
[5]: 17 [11] Fleshy roots and underground organs store food in the form of starches and sugars, allowing the plant to quickly grow when snow melts. [5] Many plants form flower buds during the summer before the summer that they open, allowing a quick bloom for the short growing season. [5]
Diluted light blue, though, is used to describe the color of fine-textured Egyptian blue that has a large amount of glass formed in its composition, which masks the blue color, and gives it a diluted appearance. It depends on the level of alkali added to the mixture, so with more alkali, more glass formed, and the more diluted the appearance. [13]
