Ziegler gives us Valrhona, a French chocolate made with a high proportion of criollo beans; Ziegler describes it as not sugar sweet, but flower sweet, and once Ziegler puts it into words, I can taste the flower sweet, just as I could taste the raisiny aftertaste..
Diamond is the hardest naturally occurring mineral, topping Mohs' Scale of Hardness with a relative hardness value of 10.Diamond is a polymorph of the element carbon, and graphite is another. While the two share the same chemistry, C (elemental carbon), they have very different structures and properties.iamond is the hardest naturally occurring mineral, topping Mohs' Scale of Hardness with a relative hardness value of 10.
There is no known natural mineral with a hardness greater than 30% the hardness of diamond, but there are synthetic materials that are, such as silicon carbide and boron carbide. These are used as abrasives and are both less than 40-50% the hardness of natural diamond (Table 4). Fig. 4 a-b. Knoop vs. Mohs' Hardness & log Knoop vs. Mohs' Hardness.
