But this does not mean that you should not be careful when handling it. The rules for using such devices are set out in the manual. Their non-compliance leads to breakage. In order not to crack the cooktop made of glass ceramic, you can not:

  • drop heavy objects on the surface. pots, pans (sometimes for the chipping is enough a knife dropped vertically with the tip down);
  • turn on several burners at full power at the same time;
  • Keep heating for a long time;
  • pour cold water on a hot stove (this does not apply to small splashes);
  • sprinkle sugar on it, which will quickly melt. after cleaning the surface will appear small damages in the material, they easily cause cracks;
  • put the pan on a non-cleaned surface, if it sticks, it will come off together with a part of the glass panel;
  • leave unattended boiling sugar syrup, and even more so. 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, microcracks are formed. the cause of serious damage;
  • Using hard sponges for cleaning. scrapers and glass ceramic sponges are required.

But even if you don’t do all this, cracks are inevitable when the vitrified clay cooktop is initially installed incorrectly: stacked against the edges. During expansion caused by heat, stress is built up in the material and the resulting crack.

If the hob glass is cracked, you can determine the cause by the nature of the damage:

  • when hit, the cracks are branched, with lintels;
  • when overheated, they appear in the working area, going to the edges;
  • From improper installation cracks the center.

Damage to the panel can be different: a small chip in a corner or a crack that crosses the entire surface with the rays branching. But regardless of their size, it is dangerous to cook on it:

And what can be done if the cooking surface cracked, affecting the working area? The best option is to call for help from a specialist. If you have skills in working with glass and glue, you can repair the damage yourself. The main requirement for the materials used is resistance to high temperature. 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 in size;
  • epoxy resin;
  • an aluminum plate the size of the crack
  • rubber spatula;
  • alcohol, gasoline or acetone for degreasing.
  • Disconnect the stove from the power supply.
  • The panel is removed.
  • Repair begins with a thorough degreasing.
  • Lubricate the crack with glue.
  • Reinforce the surfaces around the perimeter (but not under the burners) pieces of glass, planting them on silicone.
  • If there are not enough vitrified clay elements, the empty spaces are filled with epoxy resin.
  • The place of the chip is reinforced with a prepared aluminum plate, gluing it under the crack.

When the resin and glue set, the panel is put back in place.

Formation and elimination of chipped cooktop

Cooking hobs, which are now successfully entered into the kitchens of homeowners, can have different surfaces. They are made of aluminum, stainless steel, vitrified clay or enameled. Each of the coatings has its pluses and, unfortunately, minuses. For example, durability.

In order to save money, some users decide to repair the cooktop themselves. To do this, they use a material that can hold the glass ceramic, not allowing cracks to increase, resistant to high temperatures.

The most common option is considered a silicate (stationery) glue. It is used along the entire length of the crack, adding pieces of ordinary glass. When a chipped piece is missing, epoxy resin is used. The design turns out to be reliable, but it looks unaesthetic.

To repair the panel, the following tools and materials are required:

  • silicate glue;
  • silicone;
  • Rectangular pieces of glass (approximately 4×9 cm);
  • epoxy resin;
  • rubber spatula;
  • Plate made of aluminum, the size depends on the size of the crack.
  • The stove is unplugged and allowed to cool.
  • The panel is removed and wiped with a degreasing agent.

The use of pots with thick or uneven bottoms or aluminum cookware not only reduces the efficiency of the glass ceramic hob, but can also cause noticeable marks on its surface. In addition, melted plastic and sugar can ruin the appearance of the product.

Manufacturers advise to observe a number of rules when using the glass surface: you can not cook food on the broken panels; it is forbidden to touch metal dishes with wet hands; the surface must be cleaned with special agents, in order to avoid damage.

  • Cyanoacrylate (superglue). will not work for us in any way, because the maximum temperature of use is 80 degrees
  • Epoxy resin
  • Silicate glue (office supplies, liquid glass)
  • Silicone sealant. temperature up to 200 degrees.
  • First you need to apply a small amount of paste to the device itself;
  • After that you start the polishing process with a cloth or cotton pad. You need to move in circles around the device, carefully passing the place of the scratch itself;
  • After that it is necessary to clean the screen from the paste.

What to do if you break the hob?

Many modern kitchens are equipped with hobs, which are not inferior to the technical characteristics of conventional gas and electric stoves, and their range allows you to fit harmoniously into any design of kitchen sets.

The materials from which the panels are made are an important element in the kitchen. They depend on the functionality of household appliances and ease of use.

Another advantage of the hob is considered a rational use of space. The modern market offers many options for devices. They differ in their functions, materials of manufacture and design, and also have their disadvantages and advantages.

Material such as glass is used on gas, electric and induction hobs. It costs more than enameled surfaces, but the price is justified.

  • Smooth and even surface;
  • The food is cooked quickly because the plate heats up only in the place where it is needed at that moment;
  • easy to clean. fresh stains can be removed with a regular sponge, and old and serious dirt can be cleaned with special scrapers;
  • A large range of colors, as well as various designs tempt potential customers.

However, this technique is quite fragile. If you drop an object weighing two kilograms or any sharp object on the hob, it can crack or split. Therefore, in order not to break the panel, it is necessary to look after it carefully and attentively.

Fans of gas stoves, when they decide to buy a hob, but leave the gas, face the choice: tempered glass or glass ceramic.

In fact, it makes no difference, because only the burner gets hot. It is possible to break both, but the glass ceramic will break into pieces, while the tempered glass will be covered with cracks.

Electric cooktops do not use tempered glass, which heats completely, but the maximum temperature it can withstand is lower than the maximum heat.

Ceramic glass can withstand twice the temperature of tempered glass.

The positive and negative characteristics of glass ceramic are as follows:

  • durable than tempered glass;
  • is well able to withstand temperature fluctuations;
  • it has a high heat resistance;
  • Is afraid of pitting shocks;
  • a special cookware with a flat bottom is needed;
  • Ceramic glass hob is more expensive than tempered glass.

Advantages and disadvantages of tempered glass:

If you choose a panel for a gas stove, the experts are inclined to tempered glass, as it is a budget option, visually does not differ from ceramic glass. Sufficient mechanical properties for full performance.

  • The hob is not installed correctly. Under the influence of a powerful voltage cooker hob “parted”.
  • The surface can be damaged point by point, such as dropping a knife.
  • Cookware stuck to the panel. Cooking jam, for example, causes it to run out and slide under the pan which is stuck. Cookware breaks off, usually with glass.
  • Temperature fluctuations negatively affect the glass.
  • Heated sugar, once on the panel, gets into the structure of the material. Cleaning the surface leads to damage, in particular to chips.
