Alchemy in the medieval Islamic world was like magic potions and experiments that were done a long time ago in places like Arabia and Persia. It was like making things with special ingredients and mixing them in special ways to try and turn things into gold or find a way to live forever.
In those times, people believed that alchemy was a way to gain knowledge about the world around them and understand how things worked. Alchemists would try to create special substances like elixirs or powders that could transform things and even heal people.
They would experiment with different metals, minerals, and chemicals to try and find ways to purify them and make them more powerful. They would also write down their experiments and discoveries in special books called "alchemy texts".
Many famous scientists and philosophers like Ibn al-Haytham and Avicenna were also alchemists and contributed a lot to the field. They were especially interested in learning how to change base metals into gold, and many of them believed that this was possible through alchemy.
Although alchemists in the medieval Islamic world did not actually succeed in creating gold, their experiments led to many important discoveries in chemistry and medicine that still impact our understanding of the world today.
