Carbon copy of mail

A carbon copy (CC) of mail refers to a copy of a letter or document that is made by pressing the original onto a sheet of carbon paper, which is a special type of paper coated with a layer of carbon powder. The carbon powder is transferred to the copy paper, creating a duplicate of the original text.

Carbon copies were commonly used in the past, especially in business and official correspondence, to create multiple copies of a document. The original document would be written on the top sheet of paper, and the carbon paper would be placed underneath. When the document was written or typed, the carbon powder would transfer the text to the copy paper, creating a duplicate copy.

Here's an example of how carbon copies were used:

1. The sender would write or type the original document on the top sheet of paper.
2. A sheet of carbon paper would be placed underneath the original document.
3. The sender would write or type the same text on the original document, and the carbon powder would transfer the text to the copy paper.
4. The sender would then remove the original document and the carbon paper, leaving a duplicate copy of the document on the copy paper.

Carbon copies were widely used until the advent of photocopying and digital technology, which made it easier and more efficient to create multiple copies of a document. Today, carbon copies are largely a relic of the past, but they remain a nostalgic reminder of a bygone era.
