What Is A Glass Top Gas Stove Made Of?

The top material of a glass top gas stove is mostly made up of hardened, tempered, or toughened glass. These are the best materials for having higher tensile strength and better resistance to heat and impact damage than ordinary glass, so they do not break easily. Sometimes ceramic and glass are blended together to make the top surface.

These stoves look sleek and gorgeous because of the crystal clear glass top surface. If you want a beautiful kitchen worthy of a delightful cooking experience, a glass top gas stove with hardened glass is an ideal choice.

The Reasons Behind Cracking Of Glass Top

There can be various reasons for a broken glass top gas stove. The main causes for cracking or shattering of the glass plate are-

1. Inadequate Quality Of Glass

If the glass material used for making the top surface is not of good quality, there are high chances that the material will certainly break or shatter at some point in time. Unlike hardened or tempered glass, untreated glass is not strong enough and easily breaks when exposed to heat. So, if your gas stove glass top is not manufactured through heat treatment, it can be shattered into many pieces.

If you check the pattern of breaking, you will notice that it happens more frequently for specific products. This is because of the quality of the glass. On the other hand, similar cracking does not happen for good-quality gas stoves like Prestige Royale Plus.

2. Manufacturing Defects

If the quality of the glass is adequate, but it still cracks, manufacturing defect can be the reason. If the glass top gas stove was already not designed or constructed in the right way, there might be some defects that may lead to its damage.

3. Sudden Temperature Fluctuation And Extreme Heat

If the quality of the glass is good and there are no manufacturing defects, the apparent reason is thermal shock. When the glass top at normal room temperature suddenly gets exposed to high temperature, there is a probability of shattering. Thus, controlling the flame temperature is necessary for smooth operation.

Sometimes hot spots on the glass occurs while cooking or reheating the food. Heavy spillage of hot food, heat-retaining cookware, and melting of any plastic or enameled material of the utensils can also cause cracking.

Moreover, if you continuously use a glass top gas stove for a very long period, the glass will continuously get exposed to extreme heat, weakening its strength and resulting in cracking. For this reason, people are often hesitant to use gas tandoors on the glass top gas stove which requires additional tools for safe cooking.

4. Impact Of Kitchenware

Although glass top stoves are durable, they cannot withstand the mishandling of heavy cookware. If you mistakenly drop a heavy object on the glass top, there are high chances that the gas stove glass top will crack.

Also, if you tug anything hard over the glass top, it will create micro scratches on the top surface, and with time, the crack propagates, and the glass top wears out, leading to its cracking.

No, it is unsafe to use any broken glass top gas stove. A cracked glass top can be very dangerous because you might hurt yourself while cooking. The metal frame can also get heated up, which is not good. So, for safety reasons, you must not use a stove with broken glass.

Can Gas Stove Glass Be Replaced?

Avoid using heavy kitchenware made of ceramic or cast iron, as they have an uneven surface, so they are likely to create marks and scratches on the glass top.

Clean The Glass Top Regularly

Make sure that you clean the glass top every time you finish cooking. It will prevent any build-ups and hot spots which may have been caused due to food residues.

Also, wiping with a wet cloth will help in cooling down the glass top. You can clean any gas stove with vinegar or baking soda with the help of a toothbrush or soft cloth. But never use an abrasive cleaner as it can slowly damage the glass.
