Nucleation, growth mechanisms, supersaturation, crystal habit modifiers, twinning, and epitaxy explained.

Prismatic, tabular, acicular, botryoidal, dendritic habits; how the growth environment affects crystal form.

Idiochromatic vs allochromatic color, color centers, pleochroism, fluorescence, phosphorescence, and thermoluminescence.

Alum, sugar, copper sulfate, and bismuth crystals; equipment needed, step-by-step instructions, and safety considerations.
