Quartz is very resistant to both chemicals and heat. It is therefore often used as a foundry sand. With a melting temperature higher than most metals it can be used for the molds and cores of common foundry work. Refractory brick are often made of quartz sand because of its high heat resistance.Quartz sand is also used as a flux in the smelting of metals.he high hardness of quartz, seven on the Mohs Scale, makes it harder than most other natural substances. As such it is an excellent abrasive material. Quartz sands and finely ground silica sand are used for sand blasting, scouring cleansers, grinding media, and grit for sanding and sawing.
ANSWER What kind of flour do you mean? 1 US teaspoon contains 2.5 g wheat flour, 3.5 g potato flour, 3.2 g corn flour.
One cup of all-purpose white flour is 125 g, or a density of 125 g/cup. To determine how many grams of flour to use in a recipe, multiply 125 by the number of cups required. Remember that 1/4 cup is 0.25 cups, 1/3 cup is 0.33 cups and 1/2 cup is 0.5 cups. This results in the following conversions: 1/2 cup = 62 g; 1/3 cup = 42 g; 1/4 cup = 31 g.
