Heating Quills: Using a paperclip reshaped into a tiny hook and a lot of patience, I removed the inner membranes from the quill shafts so that they would not block the even distribution of heat when curing. I heated some fine sand in a large frying pan for about half an hour, stirring it with a wooden spoon periodically to make sure it heated evenly. The quills were cleared of all excess water and the empty shaft filled with hot sand using a spoon, then the shafts were plunged into the hot sand for a few seconds at a time, making sure not to push them all the way to the metal underneath. They were fully cured when inspection showed that they had turned transparent, but were not yet blistering or scorched. I scraped off the shafts’ outer membranes with my thumbnail, and they were ready to cut.
