How to Choose the Right Glass Microwave Cover
Understanding the Core Benefits
Glass microwave covers offer a significant upgrade over plastic alternatives, primarily in terms of hygiene and safety. They prevent splatters, ensuring a cleaner microwave, and avoid the potential for harmful chemicals leaching into your food. However, not all glass covers are created equal. Considering a few key features will help you find the best fit for your needs.
Key Features to Consider
Material & Durability
The type of glass matters. Borosilicate glass is a popular choice due to its superior resistance to thermal shock – meaning it’s less likely to shatter from rapid temperature changes. Tempered glass is another good option, offering strength and durability. Cheaper covers might use standard glass, which is more prone to breaking. A heavier weight generally indicates a thicker, more durable glass. Consider how often you microwave and the types of foods you typically heat. Frequent use or heating high-fat content foods that splatter aggressively calls for a more robust glass.
Ventilation System
Effective ventilation is crucial for even heating and preventing messes. Look for covers with vent holes or slits. These allow steam to escape, preventing food from becoming soggy and reducing the risk of burns when removing the cover. Dual-hole systems generally offer better steam release than single-hole designs. The placement of the vent is also important – vents closer to the edge reduce the chance of steam hitting your hand.
Size & Shape
Glass covers come in various sizes and shapes. Measure your commonly used dishes (bowls, plates, containers) to ensure the cover will fit comfortably. Tall covers are ideal for deeper dishes or when reheating larger portions. Universal covers often have flexible edges to accommodate a range of sizes, but may not provide as secure a fit as a specifically sized cover. Consider the diameter of your microwave turntable as well, to ensure the cover doesn’t obstruct rotation.
Handle & Ease of Use
A heat-resistant handle is a must-have for safe and easy handling. Silicone handles are common and stay relatively cool to the touch, even after microwaving. Look for a handle that provides a firm grip to prevent accidental drops. Some covers come with gloves or mitts for added protection. Additionally, consider how easy the cover is to clean – most are dishwasher safe, but some may require hand washing.
Additional Features
- Mat Included: Some sets include a silicone mat for added protection and versatility.
- Multi-Use: Covers that can double as food warmers or serving dishes offer extra value.
- Lightweight Design: Easier to handle and store, especially for those with limited strength.
- Clear Visibility: Allows you to monitor food while it’s heating without lifting the cover.
