Is the pencil lead poisonous?
In fact, pencil leads are not poisonous, lead is poisonous, and the main raw materials for making pencil leads are graphite and clay, so pencil leads are non-toxic.
The main components of the pencil core are graphite and clay. Graphite is a scaly solid with metallic luster. Among them, there are carbon-carbon chemical bonds. The layers are Van der Waals forces. The carbon-carbon chemical bonds are very stable. It’s very difficult. This is why diamond and graphite are both made of carbon, but the physical properties and prices are very different. There is nothing in the human body that can break the carbon-carbon chemical bond, so it is safe to say that the pencil lead is safe (unless The clay added inside is harmful to human health).
