{"product_id":"roman-plinth-grey-travertine","title":"The Roman Plinth — Grey Travertine","description":"\u003cp\u003eNot all thermal water carries the same mineral load. When the calcium-rich springs at Tivoli mixed with volcanic sediment from the Alban Hills — ash, silica, fine particulate from centuries of geothermal activity — the resulting limestone shifted. What reads as warm ivory in pure carbonate conditions moved toward dove grey, slate, the color of stone that has absorbed a different mineral history. The grey is not a surface treatment. It is a chemical record.\u003c\/p\u003e\u003cp\u003eGrey travertine is the atypical variant of this formation. Its tone makes it distinctly architectural — the coloring sits closer to concrete, to the aggregate used in modernist construction, to the material palette of Tadao Ando or Herzog and de Meuron. It reads as cold in the geological sense: formed under conditions distinct from the warmer beige deposits. The block is cut to the same dimensions as the rest of the Roman Plinth series — 17.7\" × 12.6\" × 12.6\" (45 × 32 × 32 cm), 121 lbs (55 kg) — but occupies a room differently.\u003c\/p\u003e\u003cp\u003eFour sides are left raw: the pore structure visible, the horizontal strata legible, the compressed mineral record exposed. The top surface is sanded matte. Against concrete floors or dark oak, the grey disappears into the architecture — which is precisely when a piece of stone furniture does its best work.\u003c\/p\u003e\u003cp\u003eProduced in 4–6 weeks.
