Are There Temperature Limitations for Using a Double Handle Enamel Pot?

As the performance requirements for kitchenware for home cooking increase, Double Handle Enamel Pot is widely welcomed by consumers for its beauty, corrosion resistance and easy cleaning. However, users generally have questions: Are there temperature restrictions for this type of pot? How to avoid damage caused by improper temperature?
1. The temperature resistance principle of double handle enamel pot
Double Handle Enamel Pot is made of a metal substrate (usually cast iron or low carbon steel) and multi-layer glass glaze sintered at high temperature. Its temperature resistance is mainly affected by the following factors:

Glaze stability: high-quality enamel glaze can withstand instantaneous temperatures from -30°C to 350°C, but long-term exposure to extreme temperatures will accelerate glaze aging.
Metal substrate thermal expansion coefficient: The difference in thermal expansion rate between cast iron and glaze must be controlled within 0.8%, otherwise the sudden change of cold and hot will easily cause the glaze to crack.
2. Key temperature thresholds and risk warnings
1. Upper limit of high temperature use
Safe cooking temperature: It is recommended not to exceed 250°C (if baking in the oven, confirm the product label in advance).
Risk point: Exceeding 300°C may cause the glaze to soften and release trace heavy metals (such as lead and cadmium), posing a food safety hazard.
2. Low temperature use scenario
Direct heating after freezing/refrigeration: After taking it out of the refrigerator, it needs to be left to stand for 10 minutes to restore to room temperature to avoid "thermal shock rupture" caused by a temperature difference of more than 150°C.
Defrosting restrictions: It is forbidden to place the frozen pot directly on an open flame or electric ceramic stove.
3. Scientific use suggestions
Heat source adaptability
Induction cooker: It needs to be matched with a magnetic bottom steel billet model, and the power is recommended to be ≤2000W.
Gas stove: The flame should not exceed the outer edge of the bottom of the pot to prevent carbonization of the glaze on the side wall.
Heat management skills
Preheating stage: Slowly heat up with medium and small fire (3-5 minutes) to avoid empty burning.
Cooling stage: Cool naturally to below 60°C before cleaning to prevent micro-cracks on the glaze.
Damage warning signal

When star-shaped cracks or partial peeling appear on the glaze, stop using it immediately to avoid oxidation of the metal substrate and contamination of food.
4. Industry certification standard reference

According to GB/T 15067.2-2016 Daily Enamel Products and EU EN-13834 standard, compliant enamel cookware must pass:

Hot and cold cycle test (-20°C to 250°C alternating 10 times without cracking)
Lead and cadmium migration test (<0.5mg/L when soaked in acidic food)
Conclusion: Balance performance and safety
The temperature limit of the Double Handle Enamel Pot is essentially an objective law of material science, not a design defect. By reasonably controlling the cooking scene (such as avoiding frying and stir-frying) and choosing open flame/oven compatible models, users can maximize the product life. It is recommended to give priority to brands certified by SGS or FDA, and regularly check the integrity of the glaze to ensure cooking safety and experience.
