Tin Brick

Tin stops mattering the moment you find a better ore, and this is the standard way to spend the remainder. Placed brick keeps the faint sparkle the raw ore has, so a wall of it catches torchlight in a way plain stone never will. That reads well as a floor or a trim line and gets tiring across a whole facade.

Tin Plating takes the same ingredients and gives you the same color with a smooth panelled face instead of brickwork. Work out which look you want before you commit the stack, since they are separate recipes off the raw ore. Neither has a sell value, so there is no money argument either way.
