Since lead does not dissolve in brass, as the alloy cools, it forms grains of brass; the lead is found in inclusions within the grains, but also along the grain boundaries, which form a network like that of a pile of soap bubbles (the grains being the spaces inside the bubbles). There may thus be significant lead leaching from alloys which seem ...

Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to ...
4. Spices. Spices like turmeric, paprika, and chili powder can contain lead, sometimes at alarming levels. A lot of this contamination comes from poor farming practices, where spices are grown in ...
