On the cooktop. Use low to medium heat for most cooking. As a guide, avoid the top quarter of your cooktop's settings; on a 1–10 dial, stay at 7 or below. Medium-high suits tasks like stir-frying or boiling water. If butter smokes or browns quickly, turn the heat down.
Preheating. Place the pan on medium heat for 2–3 minutes before adding food. Then sprinkle a few drops of water on the surface. If the water sizzles or beads, the pan is ready. If it evaporates instantly, turn the heat down. Never leave an empty pan on the heat for more than 5 minutes.
In the oven. Oven limits vary by range. CXD pans are oven safe up to 260°C; check each product page for others. Keep cookware at least 5cm from heating elements, and don't use it under the grill element.
