What Is That Granite Slab? (Spoiler: It’s Not Just Leftover Stone)

Before quartz and engineered stone took over kitchens, natural granite countertops were a luxury investment—beautiful, durable, but surprisingly vulnerable to one thing: heat.

When you place a scorching-hot pot or pan directly on granite, you risk:

🔥 Thermal shock: Sudden temperature changes can cause hairline cracks or even splits

🌫️ Discoloration: White “ghost rings” where the stone’s sealant or finish has been damaged

💥 Long-term damage: Repeated exposure weakens the stone’s integrity

So what did smart homeowners do? They used granite heat pads—polished remnants from their countertop installation, given to them by the fabricator as a practical bonus.

✅ These weren’t afterthoughts—they were intentional safeguards.
