Harmful Ingredients of Brick Lime. Excess lime melts the bricks and disfigures it. If CaCO 3 exists (in the purest form, i.e., if it contains at least 95% CaO) in lime-lump in brick clay, it converts into quicklime on burning. When these bricks come in contact with water, quicklime slakes and expands.
