The most important thing to do before baking bread is to preheat the oven. If you don't preheat the oven and put the bread in directly, the crust will be burnt and the inside will not be cooked.
Besides, the temperature and time of baking is also related to the type of bread and oven. Generally speaking, big toast takes longer to bake, usually about 45 minutes; while small cooking bread is baked for about 12 - 15 minutes.
Crunchy breads with a dry, crisp crust have the lowest calorie count, and are best eaten while still warm when the crust is crisp and firm from baking. Buttery breads and most fancy snack breads are added after the bread is toasted.
