The steel handles can become hot if the casseroles are used for a long time. The casseroles are made of a perfectly conductive material, which makes the transfer of heat to the handles unavoidable.
Please check the following instructions:
When cooking on a gas stove, we recommend using a flame circle that is the same size as the bottom of the casserole.
Always use oven gloves.
Be extra careful when removing the casserole from a hot oven or using it on a gas stove.
