Alimacani art students are learning the science of the clay making process. We compared the steps of making a cake in a kitchen oven to that of clay fired in a kiln explaining that the application of heat makes big changes.
We discussed how primitive cultures fired their pottery by digging holes in the ground, filling with dried leaves and twigs, and placing pottery on top. They started a fire by rubbing two sticks together, then covered it all with dirt. Days later, they dug up their clay pieces to find then strong and hard.
