Stoneware, with its rustic charm and remarkable durability, has become a kitchen and dining staple for many. Its inherent robustness makes it seem almost indestructible, but appearances can be deceiving. While stoneware is significantly more resilient than earthenware or porcelain, it still demands careful handling to ensure its longevity and maintain its aesthetic appeal. Understanding the limitations of stoneware and avoiding certain practices is key to preventing damage and enjoying your pieces for years to come. This guide delves into the specifics of what you should never do with your stoneware, offering practical advice and insights to protect your investment.
Understanding the Composition and Properties of Stoneware
Before we dive into the “don’ts,” let’s quickly recap what stoneware actually is. It’s a type of pottery fired at relatively high temperatures (typically between 2100 and 2300 degrees Fahrenheit). This high firing temperature vitrifies the clay, making it non-porous and remarkably strong. The result is a dense, durable material that’s resistant to chipping and cracking – but not impervious.
The specific composition of the clay body used to make stoneware can vary, influencing its final properties. Some stoneware contains additives like feldspar or silica, further enhancing its strength and durability. However, regardless of the specific composition, all stoneware shares certain characteristics that dictate how it should be treated.
Extreme Temperature Changes: The Silent Killer of Stoneware
Sudden and drastic temperature changes are perhaps the biggest threat to your stoneware. This is because stoneware, like all ceramics, expands and contracts with temperature fluctuations. While stoneware is more resistant to thermal shock than some other materials, rapid temperature swings can create stress within the material, leading to cracking or even shattering.
Avoid Direct Transfer from Freezer to Oven (and Vice Versa)
This is a cardinal rule of stoneware care. Taking a dish straight from the freezer and placing it directly into a preheated oven is a recipe for disaster. The extreme temperature difference causes immense stress on the stoneware, significantly increasing the risk of breakage. Similarly, removing a hot dish from the oven and immediately plunging it into cold water (or placing it on a cold surface) can have the same devastating effect.
Instead, allow stoneware to gradually adjust to temperature changes. If you’re taking something from the freezer to the oven, let it thaw in the refrigerator first. Similarly, let hot dishes cool down at room temperature before washing them. This simple precaution can save you a lot of heartbreak (and the cost of replacing broken dishes).
Be Mindful of Hot Surfaces and Cold Countertops
Even less extreme temperature differences can be harmful over time. Placing a hot stoneware baking dish directly onto a cold granite or marble countertop can create enough stress to cause cracking. Always use a trivet or hot pad to protect your surfaces and your stoneware. Similarly, avoid placing cold stoneware directly onto a hot stovetop.
Harsh Cleaning Practices: Scratches and Damage to Glaze
While stoneware is known for its durability, its glaze is not impervious to damage. Harsh cleaning practices can scratch and dull the glaze over time, diminishing its aesthetic appeal and potentially making it more susceptible to staining.
Avoid Abrasive Cleaners and Scrub Pads
Never use abrasive cleaners like scouring powders, steel wool, or harsh scrub pads on your stoneware. These materials can easily scratch the glaze, leaving unsightly marks and creating a rough surface that’s more likely to trap food particles.
Instead, opt for gentle dish soap and a soft sponge or cloth. For stubborn food residue, try soaking the dish in warm, soapy water for a while before attempting to scrub it. You can also use a paste of baking soda and water to gently scrub away tough stains.
The Dishwasher Dilemma: Proceed with Caution
Many stoneware pieces are marketed as dishwasher-safe, but frequent dishwasher use can still take a toll on the glaze over time. The harsh detergents and high water temperatures in dishwashers can gradually erode the glaze, leading to fading and scratching.
If you choose to wash your stoneware in the dishwasher, use a gentle cycle and a mild detergent. Position the pieces carefully to prevent them from knocking against each other during the wash cycle. Hand washing is always the gentler option, especially for delicate or antique stoneware pieces.
Physical Abuse: Dropping, Banging, and Mishandling
This might seem obvious, but it’s worth emphasizing: stoneware is not indestructible. Dropping it, banging it against hard surfaces, or mishandling it in any way can lead to chips, cracks, or even complete breakage.
Handle with Care, Especially When Wet
Stoneware can become slippery when wet, making it more prone to being dropped. Always handle wet stoneware with care, using both hands if necessary. Be especially careful when removing it from the dishwasher or washing it by hand.
Avoid Stacking Heavily
While stoneware is strong, stacking heavy items on top of it can put undue stress on the lower pieces, potentially leading to cracking or breakage. When storing your stoneware, avoid stacking it too high or placing excessively heavy items on top.
Microwave Misuse: A Hidden Danger
While some stoneware is microwave-safe, it’s crucial to check the manufacturer’s instructions before microwaving any piece. Not all stoneware is created equal, and some may contain metallic elements that can cause arcing or sparking in the microwave.
Beware of Metallic Accents
Stoneware with metallic accents (such as gold or silver trim) should never be microwaved. The metal can heat up rapidly and cause damage to the stoneware or even the microwave itself.
Check for Heat Resistance
Even if your stoneware doesn’t have metallic accents, it’s still important to ensure that it’s microwave-safe. Look for a microwave-safe symbol on the bottom of the piece. If you’re unsure, err on the side of caution and avoid microwaving it.
Specific Foods and Liquids: Potential Staining Concerns
While stoneware is generally resistant to staining, certain highly pigmented foods and liquids can potentially stain the glaze, especially if the glaze is already scratched or damaged.
Tomato-Based Sauces and Highly Colored Foods
Tomato-based sauces, curries, and other highly colored foods can sometimes leave stains on stoneware, particularly if left to sit for extended periods. To minimize the risk of staining, avoid letting these foods sit in your stoneware for too long. Wash the dishes promptly after use.
Coffee and Tea
Coffee and tea can also cause staining, especially in unglazed stoneware or stoneware with a porous glaze. To prevent staining, rinse your stoneware immediately after use and avoid letting coffee or tea dregs sit in the cups for extended periods.
Ignoring Cracks and Chips: A Recipe for Disaster
Even a small crack or chip in your stoneware can compromise its structural integrity and make it more susceptible to further damage. Ignoring these imperfections can ultimately lead to breakage and potentially pose a safety hazard.
Inspect Regularly for Damage
Periodically inspect your stoneware for any signs of cracks, chips, or other damage. Pay particular attention to the rims and handles, as these are the most vulnerable areas.
Discontinue Use if Damaged
If you discover a crack or chip in your stoneware, discontinue using it for food preparation or serving. The crack can harbor bacteria, and the sharp edges of a chip can be a safety hazard. You may be able to repurpose the damaged piece for decorative purposes, but it’s best to avoid using it for food-related activities.
Storing Stoneware Improperly: Potential for Damage
How you store your stoneware can also impact its longevity. Improper storage can lead to scratches, chips, or even breakage.
Use Dividers or Padding
When stacking stoneware, use dividers or padding between the pieces to prevent them from scratching or chipping each other. Felt pads or even paper towels can be effective dividers.
Store in a Safe Place
Store your stoneware in a safe place where it’s unlikely to be knocked over or bumped into. Avoid storing it in high cabinets where it could be easily dropped.
