The main staircase connected the patio and the comfortable and business-like offices on the ground floor to the second floor, which

The History of Glazed Brick and Structural Glazed Facing Tile Structural Glazed Brick and Tile were first used in the US in the early 20th century. Many of these first glazed units were manufactured as “salt glazed” brick and tile. The salt then vaporized and chemically mixed with the silicates of the body to form the salt glaze finish. This type of glazing has been discontinued for environmental reasons. Eighteenth-century Moorish lanterns illuminate the passage by night and shed a quiet light on a bewitching madonna in her shadowed niche.
