Why the hob glass is cracking
Manufacturers claim: glass ceramic hob can withstand up to 25 kg per cm2. But that doesn’t mean you shouldn’t be careful when handling it. The rules of use of such devices are set out in the manual. Failure to follow these instructions will result in damage. In order not to crack the cooking surface of glass ceramic, you can not:
- drop heavy objects on the surface. pots, pans (sometimes a knife dropped vertically with the tip down is enough for a chipping);
- Make sure you have several burners running at full power at the same time;
- Maintain the oven on high temperatures for extended periods of time;
- pour cold water on the hot plate (this does not apply to small splashes);
- spill sugar on it, which will quickly melt. after cleaning the surface will appear small damages in the material, they easily cause cracks;
- to put the pot on the surface not cleaned, if it sticks, it will come off together with a part of the glass panel;
- to leave unattended boiling sugar syrup, and moreover. jam, if they overflow over the edge, it is impossible to remove them without micro-injuries to the panel;
- cook food in aluminum cookware, with a flat or concave, but not convex bottom;
- use abrasive materials for maintenance, they scratch the surface, micro-cracks are formed. the cause of serious damage;
- use hard sponges for cleaning. scrapers and sponges for glass ceramics are required.
But even if you do not do all this, cracks are inevitable when the cooktop glass ceramic initially installed incorrectly: laid against the edges. When heat causes expansion, tension builds up in the material and the result is a crack.
If the glass of the hob breaks, by the nature of the damage you can determine the cause:
- on impact, the cracks are branched, with lintels;
- When overheated, they appear in the work area, going to the edges;
- the center is cracked due to improper installation.
Damage to the panel can be different: a small chip in a corner or a crack that crosses the entire surface with the rays. But regardless of their size, cooking on it is dangerous:
- The operation of the stove is disturbed;
- Heat escapes through cracks;
- the size of the cracks increases;
- There is a danger of electric shock, especially if you touch the wet pan with your hands.
Regardless of the extent of the damage, the stove must not be used.
If the hob broke, what to do in this case? There are only 2 options for further action: replacing the panel with a new one, repairing the damage. The choice is determined by the size of the crack and the skills of the owner. There is a third option. a gentle: the replacement of the panel, and sometimes the stove in the service center at the expense of the manufacturer, if the warranty is still valid. This is possible when the cause is a factory defect. If the glass ceramic hob cracked because of improper use of the stove, you will have to pay for its replacement.
Elimination of chipped hob surface
Even small scratches can develop into a huge problem: The vitrified clay surface becomes cracked. There are two ways to remove the smallest damage:
- A paste-like mixture of soda and water is covered with a soft cloth, polish the surface with it in a circular motion, all that is left is removed with a dry towel;
- a composition designed for polishing surfaces made of metal, cover a cotton swab and wipe the top of the plate, paper towels remove the remnants.
You should test the product on a small area before using it. If everything is in order, proceed to remove the micro-damage.
And what can be done if the hob cracked, affecting the work area? The best option is to call for help from a specialist. If you have skills in working with glass and glue, you can fix the damage yourself. The main requirement for the materials used. resistance to high temperature. You will need:
- Glue. silicate, Cosmophen (if the place of damage is not heated above 50 degrees) or cyanoacrylate;
- silicone;
- Pieces of glass 4-5×9 cm;
- epoxy resin;
- aluminum plate to the size of the crack;
- rubber trowel;
- Alcohol, gasoline, or acetone for degreasing.
- Disconnect the hob from the power supply.
- Remove the panel.
- Repair begins with a thorough degreasing.
- Lubricate the crack with glue.
- Strengthen the surface around the perimeter (but not under the burners) pieces of glass, planting them on the silicone.
- If vitrified clay elements are missing, the empty spaces are filled with epoxy resin.
- The place of the chip is reinforced by a prepared aluminum plate, gluing it under the crack.
When the resin has set and the adhesive has hardened, the panel is put back in place.
Is it possible to evaluate the durability of a panel before buying it?
No damage to the panel is assessed visually. A new surface simply should not have them, for this there is quality control in any production. It is impossible to see any damage inside the material. If they cause cracks in the glass ceramic during the warranty period, the manufacturer will replace it. This material has undoubted advantages, among which is durability.
- High efficiency because heat energy is directed strictly vertically;
- Reduced power consumption;
- rapid cooling;
- Adjusting the size of the area to be heated.
If you follow the rules of use, damage to glass ceramic panels is rare.

Cracked cooktop can be used
Stoves with glass ceramic cooking surfaces are popular: they have heat indicators, easy to use, they are easy to care for. But often cracks and scratches also occur because of heavy mechanical damage or prolonged heating. The extent of the damage can vary from a small crack to cracks that cover the entire surface area.
- lead to malfunctioning of the appliance;
- The glow temperature rises;
- The exterior of the appliance is spoiled;
- breaks can increase, leading to the complete destruction of the glass-ceramic layer;
- The stove can pass the electric current and hit the person.
Proper care and use of the appliance
To ensure that the appliance lasts a long time and is in good condition, cleaning and polishing should be done according to the following rules:
1. | Immediately remove spots that appear and recheck them when the appliance is turned on. If food or water residue burns, it will make cleaning difficult |
2. | Clean the stove when it is completely cooled down. If it is warm, a sudden change in temperature will provoke cracks |
3. | Do not place copper, aluminium or plastic cookware on the glass ceramic and avoid hitting the coating |
4. | After each cooking, wipe everything with a damp cloth and then with a dry one to remove any water spots |
5. | The selected maintenance product for the induction hob must not contain abrasives, so that scratches do not appear |
6. | Do not use metal tools, they will also leave scratches |
7. | Recommend a separate cloth for cleaning the hob. If you wash with the same cloth that you use to wash dishes, then food particles and grease will leave streaks |
Why the glass cooktop cracks
Manufacturers claim: glass ceramic panel can withstand a load of up to 25 kg per cm2. This does not mean that care must not be taken when handling the hob. The rules for using such devices are outlined in the manual. Failure to do so may result in damage. To avoid cracking your glass ceramic cooktop, you can’t:

Why damage appears on the cooktop
If the cooktop has broken, then it was preceded by the following factors:
IMPORTANT! Puncture damage is possible, for example, when a knife falls.
IMPORTANT! Plastic that has melted on a hot surface behaves in the same way. When the plastic has cured, you must turn on the stove to the lowest temperature, melt it and quickly remove it, armed with a scraper.
In some cases, cracks are a manufacturing defect caused, for example, by not following the rules of assembling the model. Often the surface is mounted very close to the edges, and it bursts when heated.
IMPORTANT! Note that an additional source of risk for the cooking surfaces is the use of cleaning detergents that are not suitable for this purpose. For example, abrasive materials strongly scratch the surface. These damages can not be noticed by eye, but eventually these damages will affect operation.
Remember that defective appliances that run on electricity are dangerous for any use. There are safety rules that must be followed:
