1. Stainless steel lids are durable and long-lasting, but their higher cost results in a pricier price tag.
2. Glass lids offer excellent transparency for monitoring cooking progress, though they are fragile and prone to breakage. They are relatively more affordable.
3. Stainless steel provides superior heat retention due to its low thermal conductivity, while glass ensures greater food safety as it resists corrosion from acids and alkalis. Both materials yield virtually identical cooking results.

Tempered glass lids for electric hot pots feature high strength and excellent transparency, allowing easy observation of food inside. However, over time, a layer of grease builds up on the lid.
