2. Nickel Sulfide Inclusions
A microscopic flaw called a nickel sulfide inclusion is another potential cause of oven glass explosions. This tiny defect, which is only about a tenth of a millimeter in diameter, can expand over time, leading to spontaneous breakage—especially when exposed to high heat, such as during a self-cleaning cycle.
Even if your oven isn’t in use, previous damage or undetected flaws can lead to a delayed explosion long after the initial impact.
Is the Self-Cleaning Function to Blame?
Many people wonder if the self-cleaning feature of ovens is dangerous. Meshulam reassures that while some cases occur during a self-cleaning cycle, most homeowners use this function without any issues. However, extreme heat exposure can trigger glass imperfections to fail, leading to breakage.
How to Prevent Your Oven Door from Shattering
While some causes—such as manufacturing defects—are beyond your control, you can take precautions to minimize the risk of oven door breakage.
1. Be Careful When Cleaning the Glass
❌ Avoid using harsh chemicals or abrasive sponges, as they can weaken the glass over time. ✅ Instead, use mild dish soap and a microfiber cloth for gentle cleaning.
2. Handle the Oven Door Gently
❌ Do not slam the oven door shut, as forceful impact can create small, invisible cracks. ✅ Close the door gently, and teach children to do the same.
