Ink pot and quill,coloured X-ray. Bird flight feathers such as this one are the sort used to make a quill. The shaft (rachis) is hollow and sharp at the tip,with this hollow section called the calamus. When dipped in a liquid such as ink,a reservoir of ink is drawn up into the hollow shaft. This can then be used for writing,with the quill dipped back into the ink pot to replenish it | |
