MELT

Incandescent blackbody glow — the halo around every growing tip is latent heat escaping.

White-hot. Four-fold δ-ferrite dendrites, the brightest melt in the instrument.

AND THEN THE MISSING DIMENSION
TRUE 3D
the same equations · all three dimensions · raymarched live

A real cubic dendrite grows six arms, not four. Flip the TRUE 3D switch and the instrument solves the full volumetric phase-field — millions of voxels — then orbits it like a CAD model: section it on any plane, x-ray it for shrinkage porosity, and print the crystal you grew as an STL. This one is growing live on your GPU right now.

COMPOSE AN ALLOY, ELEMENT BY ELEMENT
Al base + Si 7.0 wt% + Mg 0.35 wt% + Ti 0.12 wt% = A356 + TiB refiner
growth restriction factor  Q = 0 K
A356 + TiB · Q ≈ 71 K0
Al–1Zn · Q ≈ 1 K0

Same nucleation. Same cooling. Composition alone refined the metal eight-fold: the growth-restriction mechanism foundries rely on, emerging from the phase-field. Measured in this instrument, not asserted.
