From wedges of wood to slabs of stone to cast-iron plates, manhole covers have adopted new material forms throughout urban history. Often overlooked - walked over without a second thought - utility covers are portals to the underground city. The simple words: Water, Gas and Elec are the only clues to the casual observer of this hidden world below. Cast in ceramic – given new material form - but true to the manhole’s utilitarian roots, our Manhole Coasters are multifunctional. Happy under hot or cold as either a coaster or hotplate, they embody the pared-back aesthetic of the city, given new status and new life.
