Although stained glass is mostly popular in churches nowadays, the earliest discovered was in Syria from the 7th century.[dubious ] We do have evidence of techniques and recipes for obtaining stained glass by the Arabic chemist Jabir ibn Hayyan in his book Kitab al-Durra al-maknuna (The Book of the Hidden Pearl) published in the eighth century CE.[4] Orsi windows are windows made of a mixture of wood and colorful glass in the Safavid and the Qajar dynasties.
