The softest material on the hardness scale is talc, which registers a rating of 1. The hardness scale, known as Mohs hardness scale, was devised and named after the German mineralogist Friedrich Mohs.


The hardness scale, or the Mohs Hardness Scale, was developed by Friedrich Mohs, a German geologist and mineralogist, in 1812. This qualitative test was the first widely used field test among geologists.


The Mohs scale indicates the hardness of minerals by noting how scratch resistant they are. The test was developed in 1812 by the German mineralogist Friedrich Mohs. Diamond, the hardest known substance, is a 10 on the Mohs scale; talc, one of the softest known substances, is a 1.


The 12 major scales are the set of 12 scales that follow the classic diatonic formula. An octave contains seven notes: A through G, as well as five accidentals, or notes between main tones. This means there are twelve tones in all in an octave, and a major scale can be built from any of these tones


A balance scale is used for weighing substances in a chemistry laboratory. One example of a balance scale, the analytical balance scale, can measure substances with a precision of one-tenth of a milligram or one-ten-thousandth of a gram. Analytical balances can detect the weight of a single grain.


A map scale shows the relationship between the distance on the ground and the corresponding distance on a specific map. Most scales appear on the bottom or top corner of a map.


Economic theory states that economies of scale are achieved when more units of a good or service can be produced on a larger scale, with lower input costs. Dis-economies of scale also exist. These occur when production declines against a backdrop of rising input costs.


In art, scale refers to the size ratio between everything within the image. Using a scale allows the size relationships between objects to appear real or believable.


In mapmaking, a fractional scale refers to the proportion of map distance to the actual distance on the ground. It can be expressed in fractional form or as a ratio.


The scales of bony fish grow out of the dermis and are embedded in the dermis at the base of the scale. They overlap like shingles on a roof, says The Earth Life Web. Most bony-fish scales have two layers: a calcified layer on the bottom and a fibrous layer on the top. Fish don't shed their scales;
