A "'dendrite "'in metallurgy is a characteristic tree-like structure of crystals growing as molten metal freezes, the shape produced by faster growth along energetically favourable crystallographic directions.

A common practice in crystal growing is to add a foreign substance, such as a string or a rock, to the solution, thereby providing nucleation sites for facilitating crystal growth and reducing the time to fully crystallize.

:Sodium chloride ingots for optical applications are made with the Kyropulos growth method : a seed crystal in a cooled holder is lowered until it touches the melt, the melt starts crystallizing, the crystal holder is slowly raised with the crystal growing underneath.

I have done crystal growing experiments with salt, and the'saltiness " of the crystals formed out of the brine solution did not seem to vary from the first crystals formed to the last . talk ) 22 : 43, 31 January 2012 ( UTC)

Contorted stalactites may be caused by lateral outgrowths of crystals growing from the side of an active stalactite, or to deflections caused by currents of air, or to the existence of a diminutive fungus peculiar to the locality and designated from its habitat " Mucor stalaclitis ".

Growth conditions, including the surface the crystal is growing on top of ( the substrate ), may change the expected shape of the crystal; for instance, if the base of the crystal is under stress from the substrate, this may favor the crystal growing taller rather than growing outwards along the substrate.
