On the other hand, a badly scratched container will result in many lines of small crystals. To achieve a moderate number of medium-sized crystals, a container which has a few scratches works best. Likewise, adding small previously made crystals, or seed crystals, to a crystal growing project will provide nucleating sites to the solution.
Crystallization is the process by which solids form, where the atoms or molecules are highly organized into a structure known as a crystal.Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
A seed crystal is a small piece of single crystal or polycrystal material from which a large crystal of typically the same material is grown in a laboratory. Used to replicate material, the use of seed crystal to promote growth avoids the otherwise slow randomness of natural crystal growth, and allows manufacture on a scale suitable for industry.
A druse is a group of crystals of calcium oxalate, [1] silicates, or carbonates present in plants, and are thought to be a defense against herbivory due to their toxicity. . Calcium oxalate (Ca(COO) 2, CaOx) crystals are found in algae, angiosperms and gymnosperms in more than 215 fami
Raphides in Epipremnum Devil's ivy (600× magnification). Raphides (/ ˈ r æ f ɪ d i z / RAF-id-eez; singular raphide / ˈ r eɪ f aɪ d / RAY-fyde or raphis) are needle-shaped crystals of calcium oxalate monohydrate (prismatic monoclinic crystals) or calcium carbonate as aragonite (dipyramidal orthorhombic crystals), found in more than 200 families of plants.

The two men were on trial with three other rugby players, two of whom were also found guilty of rape on Friday. All five men were once teammates together at FC Grenoble.
Primary nucleation describes the transition to a new phase that does not rely on the new phase already being present, either because it is the very first nucleus of that phase to form, or because the nucleus forms far from any pre-existing piece of the new phase. Particularly in the study of crystallisation, secondary nucleation can be important.
