Pencil leads are usually made of graphite (a form of carbon).
Some pencil's are filled with lead, but rarely any nowadays. Pencils use to be filled with lead, but now pencils are typically filled with graphite as lead is poisonous to humans.
pencils are yellow because yellow is an awsome color
Mechanical pencils, like the regular kind of pencils, use graphite.
Graphite, a form of carbon, is the element from the periodic table that is used to make the "lead" in pencils. Graphite is a good conductor of electricity, and its layers provide the smooth writing surface in pencils.
Carpenter pencils are better than regular pencils for a variety of reasons. The lead in carpenter pencils are strong and are able to withstand the stress of marking on hard surfaces. Carpenter pencils are also able to survive a construction environment such as being put into a bag accompanied by heavy tools. These reasons are why carpenter pencils are better than regular pencils.

Yes, pencils can be composted since graphite contains potassium, which is important in plant and soil food web well-being. But no, they should not be placed in the compost pile since their manufacture includes color, glue, toxic phenol-filled resin, and wax.
regular pencils are better because mechanical pencils are risky because children are most likely to play with them then they snap and that's just wasting it and you have to use more and more led each time. regular is better because they are solid and firm not fiddly with and they just need to be sharpened regularly and in my opinion they are just easier to use. as you become older and have full responsibility with the mechanical pencil then your able to have more control with it you wont have to worry about wasting led thank hope it helps
The regular mineral lead Is used for making pencils and other things
