Littonware is a vintage brand of cookware known for its durability and versatility. Popular in the 1970s and 1980s, it was designed for microwave cooking, making it a favorite for quick meals. Many now wonder if these containers are still safe for modern microwaves.
With concerns about plastic safety, especially in microwaves, understanding Littonware’s properties is key. Its unique material and design set it apart from standard plastics. Knowing how to use it properly ensures safe and convenient cooking.
This article explores whether Littonware is microwave safe and how to use it correctly. It includes steps, precautions, and alternatives for safe reheating. Let’s uncover the facts about this classic cookware.
What Is Littonware?
Littonware was created by Litton Industries, a company that pioneered microwave ovens in the 1970s. Made from a light-brown, high-temperature polymer, it’s lighter than glass or metal. It was marketed specifically for microwave and conventional oven use.
The cookware is BPA-free and designed to resist thermal shock. This allows it to go from freezer to microwave without cracking. Its durability made it popular for casseroles and storage.
Littonware includes items like casserole dishes, bowls, and browning plates. Though no longer produced, it’s still found in thrift stores and online marketplaces. Its nostalgic appeal keeps it relevant today.
Why Microwave Safety Matters
Microwaves heat food by agitating water molecules, creating high temperatures. Unsafe materials can melt, warp, or leach harmful chemicals into food. This makes choosing microwave-safe containers crucial.
Littonware was designed with microwaves in mind, unlike some modern plastics. However, age and wear can affect safety. Checking its condition is essential before use.
Using the right cookware prevents health risks and appliance damage. Proper handling ensures meals are safe and enjoyable. Let’s explore Littonware’s microwave safety in detail.
Is Littonware Microwave Safe?
Yes, Littonware is microwave safe when labeled as such and used properly, as it’s made from a high-temperature polymer approved by the USDA and FDA. Designed for microwave use, it resists warping and chemical leaching if undamaged. Always follow specific guidelines to ensure safety.
Step 1: Inspect for Damage
Check Littonware for cracks, chips, or scratches before microwaving. Damaged containers may leach chemicals or break under heat. Discard any pieces showing significant wear.
Step 2: Confirm Microwave-Safe Label
Look for a microwave-safe symbol or text on the bottom of the container. Most Littonware is designed for microwaves, but verify to be certain. If no label exists, avoid microwaving.
Step 3: Prepare Food Properly
Place food in the container, avoiding overfilling to prevent spills. High-fat or high-sugar foods can overheat, so use moderate portions. This reduces stress on the container.
Step 4: Vent or Remove the Lid
Loosely place the lid or use a microwave-safe cover to allow steam to escape. Sealed lids can cause pressure buildup, risking cracks or warping. A paper towel works as a simple cover.
Step 5: Microwave on Low to Medium Power
Use 50–70% power to heat food gently for 1–2 minutes, checking periodically. Stir food halfway to ensure even heating. This prevents overheating and preserves the container’s integrity.
Step 6: Check After Heating
Inspect the container post-microwaving for warping or melting. Use oven mitts to handle hot dishes safely. Let food cool slightly before serving to avoid burns.
Precautions for Using Littonware
Don’t microwave Littonware browning or grilling plates, as they’re meant for specific cooking methods. These can overheat and damage the microwave or container. Stick to casserole dishes or bowls.
Avoid using damaged or cracked Littonware in the microwave. Even BPA-free plastics may leach chemicals if compromised. Replace worn pieces to ensure safety.
Don’t use Littonware on stovetops or under direct heat sources. It’s designed for microwaves and ovens up to 400°F, not open flames. This prevents melting or cracking.
Clean Littonware thoroughly after each use to prevent residue buildup. While often dishwasher-safe, check the label for handwashing instructions. Proper care extends its lifespan.
Alternative Microwave-Safe Containers
Glass Containers
Glass dishes, like Pyrex, are durable and microwave-safe. They don’t leach chemicals and handle high heat well. Use with a vented lid or paper towel to prevent splattering.
Ceramic Bowls
Ceramic dishes are ideal for reheating and don’t retain odors. Ensure they’re labeled microwave-safe and free of metal trim. They’re perfect for soups or casseroles.
Silicone Containers
Silicone storage containers are flexible and microwave-safe. They’re great for steaming or reheating small portions. Always vent during microwaving to release steam.
Microwave-Safe Plastic Wrap
Use microwave-safe plastic wrap or wax paper to cover food. These prevent splatters without fully sealing steam. Follow manufacturer instructions for safe use.
Comparison of Microwave-Safe Containers
| Container Type | Microwave Safety | Best For |
|---|---|---|
| Littonware | Safe if labeled | Reheating, casseroles, freezing |
| Glass (e.g., Pyrex) | Very safe | High-heat foods, long-term use |
| Ceramic | Very safe | Soups, reheating, serving directly |
Tips for Safe Microwaving
Check Littonware’s condition before each use, especially vintage pieces. Scratches or cracks can compromise safety over time. Replace if you notice significant wear.
Use short heating intervals and stir food to distribute heat evenly. This prevents hot spots that could damage the container. It also ensures consistent food temperature.
Avoid microwaving high-fat or sugary foods in Littonware for long periods. These can reach high temperatures, stressing the material. Use glass for such foods instead.
Store Littonware with lids off to prevent odor buildup. Stack carefully to avoid scratching the polymer surface. This maintains its quality for years.
Common Mistakes to Avoid
Don’t assume all Littonware is microwave-safe without checking labels. Some specialty items, like browning plates, aren’t suitable. Always verify before use.
Avoid sealing lids tightly during microwaving. Pressure buildup can crack the container or lid. Vent or remove the lid to ensure safety.
Don’t microwave Littonware straight from the freezer without thawing slightly. Extreme temperature changes can cause cracking. Let it sit briefly at room temperature.
Never use Littonware in a conventional oven above 400°F. Exceeding this limit can melt or warp the material. Follow temperature guidelines in the manual.
Creative Uses for Littonware
Reheat leftovers in Littonware casserole dishes for quick meals. Their size is perfect for family portions of pasta or stew. Cover loosely to maintain texture.
Use Littonware to freeze and reheat single-serve meals. Its freezer-to-microwave capability simplifies meal prep. Label containers for easy organization.
Store dry goods like snacks or grains in smaller Littonware containers. Their airtight seals keep contents fresh. They’re stackable for pantry efficiency.
Make microwave desserts, like mug cakes, in Littonware bowls. The even heating ensures consistent results. Add toppings after cooling for a quick treat.
Maintaining Littonware Cookware
Wash Littonware with mild soap and a soft sponge to avoid scratches. Most pieces are dishwasher-safe (top rack), but check labels. Handwashing preserves vintage items longer.
Inspect regularly for signs of wear, like cracks or discoloration. Discard damaged pieces to avoid safety risks. This ensures long-term usability.
Store in a dry, cool place to prevent degradation. Avoid stacking heavy items on top to maintain shape. Proper storage extends Littonware’s life.
If stains develop, soak in warm water with a bit of baking soda. Gently scrub to remove marks without damaging the surface. Rinse thoroughly before use.
Summary
Littonware is microwave safe when labeled as such and used correctly, thanks to its high-temperature polymer design approved by the USDA and FDA. Inspect for damage, vent lids, and use low power to ensure safety while reheating. Alternatives like glass or ceramic offer durable options for high-heat foods. Proper care and storage keep Littonware functional for years.
Always check labels and avoid damaged pieces to prevent chemical leaching or microwave damage. Littonware’s versatility makes it great for reheating, freezing, and storage. Follow these guidelines for safe, convenient cooking with this vintage cookware.
