Hi,

Don't know if this really helps, but here goes !!

Blotting paper is a type of paper or other material which is used to absorb an excess of substance (such as ink or oil) from the surface of an object.

Examples of its use include absorbing the excess ink left on parchment after writing with a fountain pen or in cosmetic papers used to remove excess lipstick or facial oils.

When used to remove ink from writings, the writing may appear in reverse on the surface of the blotting paper, a phenomenon which has been used as a plot device in a number of detective stories.

Blotting was needed once writing in dipped ink was invented and was first done by use of sand or salt poured on the wet ink. However salt especially was expensive. Blotting paper is reputed to be first referred to in the English language in the 1400s but there is a tradition in Norfolk, England that it was invented by accident at Lyng Mill on the river Wensum. This may be wrong as this was expressly a paper mill until about 1830, although it is clear that it did make paper before this time as it was referred to as Mr Hamerton's mill and there are many texts describing it as a paper mill in the 18th Century. However, the process of making blotting paper in bulk rather than by hand may be what was created at Lyng.

Certain illegal drugs, most notably LSD, are distributed on blotting paper. A liquid solution of the drug is applied to the paper, which commonly is perforated into individual doses and artfully decorated.
