A borosilicate stock pot is a transparent, non-toxic cooking pot made from a specialized type of glass that resists sudden temperature changes. Unlike regular glass, high borosilicate glass contains boron trioxide, which keeps it from cracking when transitioning from extreme cold to heat. These pots are popular for making soups, stews, and pasta because you can watch your food cook without lifting the lid Key Benefits of Borosilicate Glass Cookware Visual Cooking Control: You can easily monitor your grains, boiling pasta, or simmering soups through the crystal-clear walls without losing heat. 100% Non-Toxic: It is completely free from heavy metals, chemical coatings, BPA, and lead, making it one of the healthiest materials you can cook with. Thermal Shock Resistance: It can handle rapid temperature shifts (like pouring boiling water into a chilled pot) without warping or shattering. Effortless Cleaning: The smooth surface prevents food from sticking tightly, so it rinses clean quickly or washes easily in the dishwasher. Crucial Usage & Safety Tips While borosilicate glass is exceptionally tough compared to regular glass, it is not unbreakable. To keep your stock pot safe for years, follow these rules: Keep Heat Low to Medium: Always cook on low or medium heat settings (usually levels 1 to 4 on most stoves). High flames or maximum electric settings can cause uneven thermal stress and crack the glass. Never Heat It Dry: Always ensure there is liquid, oil, or food in the pot before turning on the burner. Heating an empty glass pot will cause damage. Avoid Frying or Searing: These pots are strictly meant for boiling, stewing, and simmering. They cannot handle the intense dry heat required for deep frying or browning meats. Check Stove Compatibility: They work beautifully on gas burners, electric coils, and ceramic cooktops. However, glass does not work on induction stoves unless you place an induction interface disk underneath it.
