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.
There is a problem with this question; the teaspoon is a measurement of volume-usually taken to be 5ml, a kilogram is a measure of weight. If you're measuring water, there â¦ are 1000ml in a kilogram of water so there would be 200 teaspoons of water in a kilo of water. However, if you're measuring flour, then there are approximately 528 grams per litre of flour, this works out to 378 teaspoons of flour to make 1 kilogram.
