WebApr 1, 2003 · Seeding is a powerful tool for the separation of nucleation and growth. In this technique, previously nucleated crystals are used as seeds and introduced into new drops equilibrated at lower levels of supersaturation. Seeding techniques can be classified into two categories based on the size of the seeds: •. WebIn general, a crystal grows from a “crystal seed,” which is a clump of sucrose molecules, a speck of dust, or a gas bubble. Stirring causes the sucrose molecules to be pushed into one another, forming crystal seeds …
