That’s why people built silos for their families, if they were wealthy enough, and for whole communities (to serve as a Bank) to store their grain

They mostly dug a leveled pit in the ground itself to keep everything cool, but more ornate silos were part of royalty or well managed cities

Vases were more common, and made, as pottery, with very cheap materials
