The baking pans on the market mainly include silica gel baking pans, glass baking pans, ceramic baking pans, aluminum alloy baking pans and carbon steel baking pans. The classification is as follows:
1, the silicone baking tray is bright in color and has an advantage in appearance. In addition, it is not sticky, easy to clean and popular, but its safety is not high and it is easy to produce harmful substances.
2. The glass baking tray has a high face value and is easy to clean, but it is generally resistant to high temperature and has the risk of lead production.
3. The ceramic baking tray is estimated to be one of the baking trays with the highest value, and it has high heat resistance, which has become the heart of many people. However, ceramics will also produce harmful substances after high temperature.
4. Aluminum alloy baking tray has good thermal conductivity, corrosion resistance and convenient cleaning, but the price is slightly higher. It is recommended to use aluminum alloy baking tray treated by anodic oxidation process.
5. The corrosion resistance and easy cleaning of carbon steel baking pan are equivalent to those of aluminum alloy, which is safer, but the thermal conductivity is slightly lower than that of aluminum alloy baking pan.

Precautions for oven use
Before baking any food, the oven needs to be preheated to the specified temperature to meet the baking time in the recipe. It takes about time to preheat the oven. If it is insufficient, the specified temperature may not be reached. If the preheating time of the oven is too long, it may also affect the service life of the oven.
To bake things in a small oven, basically you just need to put the food in, but a medium-sized oven usually contains three floors to choose from. As long as the temperature of fire and water is not specified in the recipe, the baking tray can be placed in the middle layer.
If the upper fire temperature is high and the lower fire temperature is low, unless the upper and lower fire temperatures of the oven can be adjusted separately, it is generally that the upper and lower fire temperatures are added and divided by two, and then the baking tray can be placed on the upper layer, but always pay attention to whether the surface is burnt.
Small ovens burn easily. At this time, you can cover the food with a layer of aluminum foil, or open the oven door slightly to dissipate heat. Because the medium-sized oven has enough space, the temperature can be controlled, unless the temperature is too high, too close to the fire or baked for too long, it will not be so burnt. Treatment of uneven furnace temperature Although the medium-sized oven can control the temperature, it is still difficult to compare with the professional large oven.
Take making Chinese and western snacks as an example. Because the temperature of the medium-sized oven is not as stable as that of the professional large oven, we must pay more attention to the change of temperature when baking, and we must turn or cool the snacks at the right time to avoid the uneven expansion height on both sides of the cake or bread, or the biscuits are burnt and immature.
In addition to the high temperature inside the heated oven, the shell and glass door are also very hot, so when opening or closing the oven door, it is best to wear insulating gloves to avoid being scalded by the glass door.
