A supersaturated sucrose solution slowly deposits sugar molecules onto a seed crystal or string over real days — this full 3D model runs that same crystallization kinetics (concentration, temperature-dependent solubility, and a nonlinear supersaturation-driven growth law) but compresses the real timescale so you can watch a monoclinic sugar crystal accrete layer by layer, orbiting the jar from any angle while sliders control concentration, temperature, stirring, seed size and how many simulated days pass per real second.

⚙ Under the hood

A supersaturated sucrose solution deposits sugar onto a seed crystal in real 3D — concentration, temperature, agitation and seed size drive genuine monoclinic layer-by-layer growth kinetics, time-compressed from real days.
