Qalam, the reed pen
A qalam is the calligrapher's reed pen: it is made from a cut, dried reed and used for Islamic calligraphy.
The reed is cut at a specific angle that depends on the script it is meant to write.
The word comes from the Greek word for a reed or reed pen, and in Arabic it also means writing, script and a calligraphic style.
In the Quran the qalam is revered as a symbol of wisdom and education, and Sura 68 is called Al-Qalam.
Ibn Muqla developed a standardized system of calligraphy based on the marks made with the point of a reed pen.
In Mashq Studio
In Trace, the Studio's practice window, the pen is a flat reed nib held at each script's own angle, so thick and thin strokes come from the angle of the pen, as on paper. Open the Studio, free.
