How Do You Make Pots On Runescape?

You mine clay or you can purchase it at a shop or the Grand Exchange. Then you need a bucket. Fill the bucket with water. Use the bucket of water on the clay. It will make soft clay. Take the soft clay to a pottery oven which can be found using the World Map. Use the soft clay on the oven and select Pot. This will make you a pot.

Go to south entrance in varrock and go left there is a mine.  Mine some clay.  Mix with water.  Go to barbarian village.  South end.  Potters wheel. Click on the clay then on the wheel.  Click clay pot at the bottom.  Click on pot in inventory.  Click on the oven/furnace thing. It may crack. Beware it is worth 0 coins unless there is something in it

I dont know if you mean pots for holding flour or pots as in potions.
For pots mine clay and use bucket of water to make soft clay then head to barbarian village and use on the clay oven or the wheel thing first.
For pot's potions in non members there is only one way and that is to go to the apothcary and in members you will need a vial of water use a vial on a tap or a fountain to get vial of water then use herbs and other bits on it depending on what potions you want just click the herblore skill icon to find out
