What Eraser to use?
By Pamela Queen
Different paper types, different pencils require different erasers.
The History of the eraser.
"Before rubber erasers, tablets of rubber or wax were used to erase lead
or charcoal marks from paper. Bits of rough stone such as sandstone or pumice
were used to remove small errors from parchment or papyrus documents
written in ink. Crustless bread was used as an eraser in the past; a Meiji-era
(1868-1912) Tokyo student said: "Bread erasers were used in place of
rubber erasers, and so they would give them to us with no restriction on
amount. So we thought nothing of taking these and eating a firm part to
at least slightly satisfy our hunger."[1]
