A mechanical pencil or clutch pencil is a pencil with a replaceable and mechanically extendable solid pigment core called a "lead" / ˈ l ɛ d /. The lead , often made of graphite , is not bonded to the outer casing, and the user can mechanically extend it as its point is worn away from use.
The graphite in pencils is mixed with clay during fabrication of the "lead" to help hold its shape, and would only burn at greater than 1,000 °C (1,832 °F). [ 10 ] The quantity of graphite particles actually produced during occasional writing would be too small to constitute an electrical hazard.
Forty-six years after it was banned in the U.S., many homes still have lead paint, which could potentially cause health problems.
Lead for mechanical pencils Flexible pencils. Mechanical pencils use mechanical methods to push lead through a hole at the end. These can be divided into two groups: with propelling pencils an internal mechanism is employed to push the lead out from an internal compartment, while clutch pencils merely hold the lead in place (the lead is ...
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 ...
