To cook clay pots, you need to preheat your oven to 200 degrees celsius (392 degrees fahrenheit). Once the oven is preheated, you need to mix a few ingredients together and pour the mixture into the clay pots. You should then place the clay pots in the oven and bake them for around 30 minutes. After 30 minutes, you should take the clay pots out of the oven and let them cool down before you use them.
