Most of the cookie sheet pans are made of anodized steel. Some of them have a non-stick surface, some don't. Another popular type of cookie sheet material is silicone. The silicone cookie sheets are non-stick and come in many bright colors and they are a little more expensive.
An unprepared cookie sheet is simply a cookie sheet that does not require a coating of grease and sprinkled flour.
Cookies or biscuits can be baked on a cookie sheet/oven tray or on any flat oven-suitable surface such as the base of a ceramic casserole dish. The advantages of an oven tray or cookie sheet, is that the maximum number of biscuits or cookies can be baked at once, and they can be more easily removed, as there is no side to the tray to make it difficult to get a utensil under them and slide them off the tray once they are baked.
Stoneware is much thicker and a metal cookie sheet is alot thinner and if you are going to bake cookies then pick the stoneware because the metal cookie sheet will burn the cookies.

An insulated cookie sheet is made from two thin sheets of metal with an air space in between.
Typically, a cookie sheet is aluminum.
The point of a cookie sheet is so you don't get your pan dirty. Also, because some cookie sheets have a coating so the cookies don't stick to it. LOL

No, the shape of a cookie sheet has nothing to do with cookies burning. How cookies burn in the oven is usually due to heat circulation in the oven, evenness of heat in the oven, or the position of the cookie sheet relative to the heat source.
