makeshift

Bad news...I just broke my Cloche. Every once in a while, I used it when I just had to have the crispiest of crisp crusts that I couldn't achieve with the cold oven method. Since I don't want to shell out 40+$ again, I've decided to build a homemade cloche from a terra cotta flower pot and base. But, I'm not sure if the terra cotta is food-safe or not. There's a Joann's in my neighborhood where I can get the materials so does anyone know if their materials are food safe? How can I get the material safety sheet if the employee's over there don't know?
