Unfortunately, cracks happen. So if your stove glass has been damaged from an accidental incident, there are many different types of reasons why a crack has occurred. The most common types of cracks are use and impact.
The impact damages are often caused by forcing pressure on the glass. Examples include:
- Adding too much to the firebox with wood and fuel and then closing the door.
- Banging or hitting the glass. You could accidentally bash the glass when walking by the stove.
- The screws and bolts holding the glass in position can be tightened too much. As a result of the tightening, the heat can expand the glass and break.
When wood burners are used for a long period of time, the glass can be damaged. Cracks can happen with long term use and misuse. Here are some of the most common causes of stove glass breaks and cracks:
- Too much fuel in the stove can lead to overfiring. The stove glass won’t be able to withstand the temperature and will therefore crack.
- Burning household coal is acceptable to put on an open fire. But in an enclosed fire such as a stove it can cause mini explosions because it’s a volatile fuel. These explosions can cause breaks and cracks.
- Burning petroleum-based fuels is also going to cause explosions within the stove and can cause log woodburner glass to break.
Leaving your stove glass cracked
