This explains why a cooling magma can have some crystals within it and yet remain predominantly …
WebApr 7, 2024 · Lower the temperature of the cooling bath. If very few crystals are seen, there is likely too much solvent. Return the solution to the heat source and boil off a portion of solvent, then cool again. If all else fails, the solvent can always be removed by rotary evaporation to recover the crude solid. Another crystallization can be attempted ... WebCrystal formation can be achieved by various methods, such as: cooling, evaporation, addition of a second solvent to reduce the solubility of the solute (technique known as antisolvent or drown-out), solvent layering, …
