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.
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. The addition of only one seed crystal should result in a larger single crystal.
Seed oils also get a bad rep because of their level of processing. It's more difficult to get oil out of a seed than it is, say, an olive, so seeds undergo a more intense oil extraction process.
Technically, a seed oil is a cooking oil made by pressing seeds to extract the fat. But the current pariahs are canola, corn, cottonseed, grapeseed, soy, rice bran, sunflower, and safflower oils.
Flax seeds produce a vegetable oil known as flax seed oil or linseed oil, which is one of the oldest commercial oils. It is an edible oil obtained by expeller pressing and sometimes followed by solvent extraction. Solvent-processed flax seed oil has been used for many centuries as a drying oil in painting and varnishing. [28]
