Focus: Group 14 elements (Carbon, Silicon). Carbon cannot be melted—it sublimates. You cannot "pull" a diamond crystal; you must grow it from a gas cloud. Carbon atoms rain down from methane plasma and land on a substrate plate, building the crystal layer by layer (epitaxy). Output: Diamond wafers for Aetheric Sciences computing, graphene sheets for Lorentz Aerospace hull coating, carbon nanotubes for Foundation Kinetics robotic muscles, diamond heat spreaders for Stellar Furnace reactors.

Focus: Titanium, Tungsten, Iron, Vanadium. Metals naturally want to form millions of tiny crystals as they cool. To get a single-crystal metal part, we force the metal to cool from exactly one point at the bottom. The crystallisation front moves slowly up the part, organising every atom into a single grain. Output: SX superalloy turbine blades for Lorentz drives, single-crystal iron rods for Highfield Magnetics, MS-Alloy structural skeletons for Modular Habitats, tungsten carbide heat shielding for Stellar Furnace.

Focus: Lanthanides (Neodymium, Samarium) and exotics. Complex f-orbital electron shells make these materials difficult to purify and highly reactive to oxygen. Strict inert atmosphere manufacturing. Less about structural strength, more about electromagnetic properties. Output: Super-magnets for Highfield Magnetics, doping agents sent to the C-Forge for computing diamond chips, piezoelectric crystals for Morph-Metal metamaterials.

Focus: Aluminium Oxynitride (ALON), Sapphire, specialised ceramics. You melt the material in an iridium crucible at 2000°C+ and slowly pull a "seed" crystal upwards. The liquid latches onto the seed and freezes in perfect alignment, growing massive boules. Cooling must be perfectly controlled to prevent clouding or cracking. Output: Parabola Glass (transparent armour) for Lorentz ships and Modular Habitats, YAG crystals as gain medium rods for Maxwell Continuum lasers, sapphire windows.
