Machine-made charcoal is a commonly used solid fuel, but it may break during use. Here are some ways to help avoid charcoal breakage:

1. Choose high-quality charcoal: Buy high-quality machine-made charcoal from reliable suppliers. Good quality charcoal usually has a uniform shape and structure with fewer impurities and voids. Such charcoal is stronger and more resistant to breakage.

2. Store in a dry environment: Machine-made charcoal should be kept in a dry environment during storage and use. Humid conditions can cause charcoal to absorb moisture, making it brittle and prone to breaking. It is best to store charcoal in an area that avoids exposure to rain or high humidity.

3. Avoid drastic temperature changes: Machine-made charcoal should avoid sudden temperature changes, such as from extreme heat to extreme cold or vice versa. This temperature change can cause the charcoal to expand and contract, increasing the risk of breakage. When storing and using charcoal, try to avoid exposure to extreme temperatures.

4. Slow heating and cooling: When using machine-made charcoal, try to avoid sudden high temperatures and cooling. You can start by using a smaller flame and gentle heat, gradually warming up the charcoal. Likewise, after use, the temperature should be lowered slowly to allow the charcoal to cool down gradually. This reduces stress on the charcoal and reduces the risk of breakage.

5. Pay attention to how you use it: Correct use of machine-made charcoal can also reduce the possibility of breakage. Avoid overlying the charcoal or using a flame that is too large, which can cause excessive pressure and heat stress on the charcoal. Reasonably control the firepower and burning time to reduce the load and stress of charcoal.
