None of these are necessarily crystalline or non-crystalline. However, there are some general trends as follows: Metals crystallize rapidly and are almost always polycrystalline, though there are exceptions like amorphous metal and single-crystal metals. The latter are grown synthetically, for example, fighter-jet turbines are typically made by ...
The final moisture content is around 1–2%, whereas the final moisture content in crystalline candies is 8–12%. The non-crystalline nature of glassy amorphous solids is due to the presence of inhibitors in the solution. Without an inhibitor, crystallization would occur spontaneously and rapidly as sugar cools due to its high concentration.
In condensed matter physics and materials science, an amorphous solid (or non-crystalline solid) is a solid that lacks the long-range order that is characteristic of a crystal. The terms " glass " and "glassy solid" are sometimes used synonymously with amorphous solid; however, these terms refer specifically to amorphous materials that undergo ...
Brown sugar candy resulting from caramelisation. Sugar candy is often used to sweeten tea. Northern Germany, specifically East Frisia, has an established tea culture, where a large crystal of sugar candy (Kandiszucker or in the regional dialect Kluntje) is placed at the bottom of the cup and the hot tea added, which cracks and dissolves the crystal.

Rock candy or sugar candy, [1] also called rock sugar, or crystal sugar, is a type of confection composed of relatively large sugar crystals. In some parts of the world, local variations are called Misri , nabat [ 2 ] or navat .
Chemically, sugar candies are broadly divided into two groups: crystalline candies and amorphous candies. [2] Crystalline candies are not as hard as crystals of the mineral variety, but derive their name and their texture from their microscopically organized sugar structure, formed through a process of crystallization, which makes them easy to bite or cut into.
Crystallinity refers to the degree of structural order in a solid.In a crystal, the atoms or molecules are arranged in a regular, periodic manner.The degree of crystallinity has a large influence on hardness, density, transparency and diffusion.
The definition of which foods are "confectionery" vs "bread" can vary based on cultures and laws. In Ireland, the definition of "bread" as a "staple food" for tax purposes requires that the sugar or fat content be no more than 2% of the weight of the flour, so some products sold as bread in the US would be treated as confectionery there.
