Why does a saucepan have copper bottom but plastic handle?

A saucepan has a copper bottom and a plastic handle for several reasons:

* Copper Bottom:

* Excellent Heat Conductivity: Copper is an excellent conductor of heat, meaning it heats up quickly and evenly. This allows for faster and more consistent cooking.

* Durability: Copper is a durable metal that can withstand high temperatures and is resistant to rust.

* Reactive to Acids: While copper is a good conductor, it can react with acidic foods, altering the flavor and potentially leading to discoloration. The copper bottom allows for efficient heat transfer without direct contact with the food.

* Plastic Handle:

* Heat Insulation: Plastic is a poor conductor of heat, making it safe to hold even when the saucepan is hot.

* Lightweight: Plastic is lighter than metal, making the saucepan easier to handle and maneuver.

* Durability: Plastic is durable and resistant to breakage.

* Cost-effective: Plastic is less expensive to manufacture than metal handles.

* Aesthetic Appeal: Plastic handles can be molded into different shapes and designs, adding to the saucepan's aesthetic appeal.

Therefore, combining a copper bottom and a plastic handle provides the best of both worlds: efficient heat transfer for cooking and safe, comfortable handling.
