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.

Looking at the list of poisons, you might be tempted to think lead is safer than salt or bee sting venom is safer than cyanide. Looking at the lethal dose can be misleading because some of these chemicals are cumulative poisons (e.g., lead) and others are chemicals your body naturally detoxifies in small amounts (e.g., cyanide). Individual biochemistry is also important.
