Material
Pan diffusers are commonly made from durable materials like cast iron, aluminum, or stainless steel. Cast iron retains heat well, making it ideal for long, slow cooking, while aluminum and stainless steel are lighter and easier to handle.

Design
Typically round in shape, pan diffusers feature a flat surface that rests directly on the stovetop burner. Some models include handles for easy maneuvering, while others are ring-shaped with perforations, allowing heat to disperse evenly.

Function
The primary purpose of a pan diffuser is to evenly distribute heat across the cookware placed on top of it. This ensures consistent cooking and reduces the risk of burning or scorching, especially when using cookware that is prone to uneven heating.

Usage
To use, simply place the diffuser over your stovetop burner and set it to the desired heat level. Then, place your cooking pan or pot on top of the diffuser. The diffuser helps diffuse direct heat, making it ideal for simmering, melting, or cooking at low temperatures.

Benefits
Pan diffusers are particularly useful for cooking delicate foods that require gentle heat, such as simmering sauces or melting chocolate. They also help when using cookware with poor heat distribution, preventing food from burning or overcooking.
