when to replace the existing stove glass?
Stove glass is the most often replaced part of any working wood burning stove. This heat resistant ceramic glass has excellent performance properties when it comes to heat resistance and thermal stock resistance however it is still susceptible to both breakakes and also scratches like normal glass. If your glass shatters or cracks we highly recommended that you replace this glass before working your stove for your safety and efficient working of your stove.
There are quite a few reasons why one might consider finding a replacement fire glass. Sometimes, the glass that comes with the stove is not of the highest quality and it will crack because of the heat, it could also be that soot attaches itself to the glass and, as you bake it over and over, it becomes irremovable.
