An oven is a necessary appliance in the home; housewives cook a large amount of delicious food in it. The glass in them is made heat-resistant and can serve for many years, but there are situations when part of the surface peels off from the door, or the glass breaks. In this case, there is no need to buy new equipment; the breakdown can be repaired. The only thing is to choose a special heat-resistant adhesive for the oven glass. More details about the adhesives on sale will be discussed below.
When is it necessary to glue glass?
As a standard, electric and gas stoves are equipped with several glasses that can withstand high temperatures up to +250 degrees. Even high-quality glass oven windows can crack or move away from the base over time. Not only temperature changes are a consequence of breakdowns, this can happen for other reasons:
- Mechanical impact, scratches, impacts;
- Exposure to vapors, fats. If there are scratched areas, the possibility of cracking increases;
- The use of pyrolysis (cleaning under high temperatures) increases the chances of glass damage.
The glass must be selected to be fire-resistant; the size and required structure must be correctly determined. The process of adjusting the size can be difficult, cutting requires special tools, it is better to contact specialists for this service, or look for a suitable option from the manufacturer.
Not only temperature changes are a consequence of breakdowns, this can happen for other reasons.
When is it necessary to glue glass in the oven?
As a rule, electric ovens and gas stoves have 2-3 heat-resistant glasses. The temperature inside the equipment during operation rises to +250 °C. Even if the glass is of high quality, over time it can crack or crumble. In addition to temperatures and their changes, there are other causes of failure:
- Impacts, scratches, mechanical damage.
- Action of steam, fat and other substances. If there are scratches or areas that have already been sealed, the risk increases.
- Pyrolysis function, that is, high-temperature cleaning. This is an additional burden.
What to do if glass peels off or breaks
When the owner of the oven notices the presence of a peeled off section of the glass surface, or the appearance of cracks on it, he may have a desire to continue using it in this form. The consequences can be very unpleasant:
- If the fragments get into the food, when the oven heats up, small particles of glass may fall off into the food. In an unheated state, the glass will not be scratched, it usually disintegrates into small cubes of glass, they may visually look firmly connected, but high temperatures will lead to their further destruction;
- Increasing the cooking time, when one glass is installed, the heat will actively come out;
- Rapid contamination and difficulty in cleaning the glass surface.
The appearance of cracks on one glass can be a consequence of cracking in others, so it is better to replace it quickly.
When the oven heats up, small particles of glass may fall off into the food.
