Old School RuneScape Wiki

Clay rocks are a material that players can obtain with level 1 Mining, to gain 5 Mining experience points. Clay is not recommended to train Mining as copper and tin give more experience. Clay is often used as a money making way for free players (e.g. giving 132gp each rock, making it 3696gp (~3.7k) an inventory if sold at said price). One full inventory of clay takes 56 seconds minimum. That is a very good way to make money, but sometimes, clay takes a long time to sell because of the amount of clay miners. Clay is also used to make Soft clay which is used in Crafting. To make soft clay, players will need to wet a piece of clay, use the clay ore on a liquid holder, such as a jug of water or a bucket of water. Also, mining the clay rock whilst wearing a Bracelet of clay yields soft clay. Additionally, the Humidify spell works on clay too. Some people make money by buying clay, making it into soft clay, and then selling the soft clay.
