Can You Put A Glass Measuring Cup In The Microwave? Safety Tips

Can you put a glass measuring cup in the microwave

Yes, you can microwave a glass measuring cup if it’s labeled microwave-safe. Avoid rapid temperature changes, cracks, and overheating, and use microwave-safe covers or plates when needed. Be cautious of hot surfaces.

Putting glass measuring cups in the microwave is a common question for home cooks. Glass measuring cups are convenient kitchen tools for accurately measuring ingredients for recipes. But are they safe to use in the microwave? Let’s explore the pros and cons of microwaving glass measuring cups and find out what types of cups are microwave-safe.

Why Glass Measuring Cups Are So Popular

Glass measuring cups have become a staple in most kitchens because of their many benefits:

• Accurate measurements. Glass cups allow you to precisely measure liquids and dry ingredients like flour or sugar. The clear glass makes it easy to read measurements.
• Versatile uses. In addition to measuring, glass cups can be used for mixing, microwaving, and serving. Their durability makes them an indispensable kitchen tool.
• Easy to clean. Glass measuring cups can be washed by hand or placed in the dishwasher for easy cleanup.
• Durable material. High-quality tempered glass is designed to withstand high temperatures. Glass cups won’t warp, bend, or deteriorate with regular use.
• Odor and stain-resistant. Glass doesn’t retain food odors or stains like plastic measuring cups.

For these reasons, most home cooks love the convenience and reliability of glass measuring cups. But the big question is: can they be safely used in the microwave?

Are Glass Measuring Cups Microwave Safe?

Whether glass measuring cups are microwave-safe depends on the type of glass:

Tempered Glass

Tempered glass measuring cups are specifically designed to withstand sudden temperature changes that occur in the microwave. This type of glass has been heat-treated to increase its strength so it won’t crack or shatter when heated.

Major brands like Pyrex are made of tempered glass formulated for use in the microwave. Look for labels indicating the cups are “microwave safe.” Tempered glass cups can safely be used to reheat foods or liquids in the microwave.

Untempered Glass

Regular glass measuring cups have not been treated for thermal shock resistance. Heating untempered glass too quickly can cause it to crack or break.

Untempered glass cups may be labeled “not for use in microwave” or have no microwave-safe labeling. Do not put these types of glass cups in the microwave.

Ceramic, Stoneware, or Porcelain

Some measuring cups are made of ceramic, stoneware, or porcelain. These materials are fine for microwave use unless they contain metal paints or decorations that can spark. Check the manufacturer’s guidelines to see if ceramic or stoneware cups are microwave-safe.

How to Microwave Glass Measuring Cups Safely

Follow these tips to prevent accidents when microwaving glass measuring cups:

• Only use cups labeled microwave-safe or oven-safe. Look for tempered glass.
• Never microwave empty cups. Liquids or foods absorb microwave energy. Empty cups can overheat and shatter.
• Avoid sudden temperature changes. Don’t add cold liquids to hot glass or put hot glass on cold surfaces.
• Remove lids before microwaving. Lids can cause excess pressure.
• Use mittens or potholders to handle hot glass.
• Inspect for chips or cracks before each use. Damaged cups are more prone to breaking.
• Place cups at least one inch apart and 1-2 inches away from oven walls. This prevents uneven heating.
• Heat foods for 30 seconds at a time. Stir and heat in short bursts to prevent overheating.
• Check the manufacturer’s instructions. Some glassware has specific microwave heating limits.

Why You Shouldn’t Microwave Plastic Measuring Cups

Many home cooks use plastic measuring cups because they’re inexpensive and lightweight. However, microwaving plastics comes with safety risks:

• Leaching. Plastics can leach chemicals like bisphenol A (BPA) into food and liquids when heated, especially if old or scratched.
• Burns. Plastic cups can become dangerously hot. Always use oven mitts to remove.
• Melting. Some plastics will warp, melt, or scorch when microwaved. This can release toxic fumes.
• Unless labeled microwave-safe, opt for glass or silicone measuring cups instead. Avoid microwaving plastics.

Can You Use Measuring Cups in the Oven?

Like the microwave, the high heat of an oven can damage some glass and plastics. Follow these guidelines:

• Only use oven-safe tempered glass cups. Avoid untempered glass.
• Don’t place glass in an oven during broiling. High direct heat can cause it to crack.
• Never put plastic measuring cups in a hot oven.
• For stovetop use, ensure the cups have heat-resistant handles.
• Ceramic and stainless steel cups are also oven-safe options.
• Check manufacturer instructions to verify if cups are oven-safe up to a certain temperature. Properly heat-resistant glass measuring cups can safely go from freezer to microwave, to oven.

Key Takeaways

Tempered glass measuring cups are designed for microwave safety. Look for labels indicating microwave or oven safe.

• Untempered glass can shatter when heated rapidly. Avoid it in the microwave.
• Use glass cups labeled microwave safe and follow heating precautions.
• Never microwave empty glass cups. The lack of liquid may cause cracks or breaks.
• Plastic measuring cups should be avoided in the microwave due to leaching and melting risks.
• For oven use, only microwave-safe tempered glass, ceramic, and some metal cups are safe.

With proper care, glass measuring cups are incredibly versatile tools that can be used for measuring, mixing, microwaving, and more.

Pay attention to glass type and safety labeling to decide if your measuring cups belong in the microwave or oven. Investing in high-quality heat-resistant glass cups prevents safety worries and makes your time in the kitchen easier and more enjoyable!
