This article delves into the common causes of this pesky problem and provides practical tips to keep your glass stove top crack-free and your kitchen looking sleek.

Why Does My Glass Stove Top Crack?

The glass stove top is an essential appliance in any kitchen but is also prone to cracks. Understanding the causes of a crack in the glass stove top can help you take preventative measures to avoid them. Below are the common causes of glass stovetop cracks and practical solutions to address these issues, allowing you to avoid needing stovetop replacement.

Thermal Shock

This problem occurs when a hot pan is suddenly placed on a cold stovetop or vice versa, causing the glass to expand or contract rapidly and leading to cracks. This issue is most commonly seen when a hot pan is placed on a cold stovetop.


  • Allow the stovetop to cool down before cleaning it or adding any cold objects to its surface.
  • Use a buffer, such as a towel or a trivet, between your cookware and the glass stove top to prevent rapid temperature changes and reduce the risk of thermal shock.
  • Always use low to medium heat settings to avoid exposing the stove top to extreme temperature changes.

Impact Damage 

Some broken glass cooktop occurs if heavy or sharp objects are dropped or dragged across their surface and are struck violently. Dropping a heavy or sharp object on the surface or dragging it across the surface can cause significant cracks.


  • Handle cookware and utensils carefully to avoid dropping or dragging them across the surface of the stovetop.
  • Use cookware with smooth, flat bottoms to minimize the risk of scratching or cracking the glass.
  • Avoid using heavy or sharp objects on the stovetop, such as cast iron pans or cleavers.
  • If a heavy or sharp object must be used, handle it carefully and avoid striking or dropping it on the stovetop.


Even small scratches can weaken the integrity of the glass and make it more prone to cracking. Scratches are commonly caused by using abrasive cleaning products or cooking utensils with sharp edges.


  • Clean the stovetop regularly to prevent debris from scratching the surface.
  • Use a soft cloth or sponge when cleaning the stovetop to avoid using abrasive materials that can scratch the glass.
  • Avoid using cookware with rough or damaged bottoms that can scratch the surface of the stovetop.
  • Consider using cookware with non-abrasive coatings to prevent scratches.
  • If you notice a scratch on the stovetop, avoid using abrasive cleaners or scrubbers and instead opt for a specialized glass stove top cleaner and a soft cloth.

Wear and Tear

A glass stove top may develop cracks over time due to natural wear and tear. Continuous usage and frequent heating and cooling can cause the glass to weaken, leading to cracks.


  • Avoid sliding heavy cookware or rough-bottomed pots and pans across the stovetop, as this can cause scratches and wear down the surface over time.
  • Clean the stovetop regularly with a specialized glass stove top cleaner and a soft cloth to remove any build-up and prevent wear and tear.
  • Use a protective cover for your stove top when not in use to prevent dust and debris from accumulating and causing damage over time.
  • If you notice any signs of wear and tear, such as chips or cracks, consider replacing the stovetop to prevent further damage and ensure your safety.
