Lay one hot stone on the asbestos at the bottom of the oven with the hotter side down; put a wire oven shelf on this, and the food on the wire shelf. If the food will not rise higher than the top of the pan, a hot stone may be laid directly across the pan, but if this is not possible place the second wire shelf as close over the food as the cleats at the side of the oven will permit, and the stone on this shelf, also with the hot side down. In case more than one pan is to go in at once, and two stones will not supply enough heat, hot flatirons or stove lids may be used to supplement them. It is often convenient, when the oven is heated for baking one article, to put other things in to cook at the same time, even though they may not require browning. For instance: A chicken or roast may be cooking between two stones, while on top of the upper stone the giblets may be stewing in water, or some vegetables be boiling. It will be best in such cases to heat these foods till boiling before putting them in the oven, or they will cool it too much. Such foods, as do not require browning, will not need another stone on top. It may not be wise to put so much watery food in the oven when baking anything so critical as bread or loaves of cake, as it cools the oven to some extent.

No matter how carefully the directions are given and followed some experimentation will probably be required before a novice, or even an experienced cook, will feel at ease with this new method of cookery, since the conditions may be so variable. But there is no reason why a careful observation of results and their causes should not soon lead one to become mistress of her own insulated oven, and it is likely that she will then become sufficiently attached to it to justify her perseverance.

In case a cooker-pail is to be utilized for baking it will be well to surround it, on top, bottom, and sides, with the heavy sheet asbestos described for insulating the oven. A wire rack will be needed for separating the food from too direct contact with the hot stones, and some device, such, perhaps, as an inverted wire frying-basket for supporting the upper stone.
