Pumice Quarry (2D): Vesicularity, Bulk Density & Buoyancy

2D quarry-face lab: a depth-dependent vesicularity profile φ(z) = 0.45 + 0.35·sin(πz/40) sets bulk density ρ = ρ_solid·(1−φ), a handling-intensity slider collapses vesicle walls into fines, and a water-soak timer shows a real pumice sample sinking once its open pores saturate past the 1000 kg/m³ threshold.

This 2D companion drives the same vesicularity-depth model and buoyancy physics as the 3D quarry diagram — a depth-dependent porosity profile, a handling-intensity penalty that collapses vesicle walls into fines, and bulk density from the solid-glass/pore-fraction relation — through a flat cross-section view instead of a rotating process scene, and adds a dimensional layer the 3D version doesn't have: a water-soak timer that turns the porosity model into a live floats-then-sinks demonstration, with the wet density read out in real kg/m³.
