What your dishes are releasing into your food — and why it gets worse the longer you keep them.
Most people never think about this. They probably should. 1 min read.
01 - Worn plastic dishes don't just look bad. They shed.
Melamine, plastic-coated, and composite dinnerware release microplastic particles into food. Every scratch, every dishwasher cycle, every hot meal accelerates it. A dish that looked fine two years ago is releasing more particles today than it was then. The degradation is invisible. The accumulation isn't.
Microplastics have now been found in human blood, lung tissue, breast milk, and major organs. Researchers don't yet know the full consequences — but the dishes people eat from every day are a primary source of exposure.
02 - Those hairline cracks in your glaze aren't cosmetic.
Crazing — the spiderweb of fine cracks that develops in older ceramic glaze — looks like a surface detail. It isn't. It's a breakdown of the protective layer. Bacteria collects there. Food residue settles in. No dishwasher reaches it.
A crazed dish is not cleanable. Not fully. And most dishes develop crazing well before people think to replace them.
All Hadley Pottery products are made by hand and checked for crazing, chips, cracks before leaving our factory.
03 - Older imported ceramics have a lead problem most people don't know about.
Mass-produced dishes made overseas — especially sets purchased before the 2000s — were frequently finished with glazes containing lead and cadmium. Both are toxic heavy metals. Both leach into food. Both are made significantly worse by acidic foods: tomatoes, citrus, vinegar, wine.
The older the dish and the more worn the glaze, the higher the exposure with every meal. The FDA has tightened standards considerably since the 1990s — but those standards only apply to dishes made after the rules changed. Anything older than that is subject to whatever standards existed when it was made.
04 - Heat is the accelerant. And you use heat every time you eat.
Hot food. The microwave. The dishwasher's drying cycle. Every source of heat degrades compromised dishware faster — breaking down plastic surfaces, widening glaze cracks, and increasing the rate at which materials migrate into food.
A dish that seemed fine with cold food behaves differently at 150 degrees. Most people never make that connection.
All Hadley Pottery products are microwave, dishwasher, and food safe.
05 - The fix is simpler than people think.
Real stoneware — high-fired, lead-free, cadmium-free — has been the safest vessel for food and drink for centuries. No coatings to degrade. No plasticizers. No hidden metals. The glaze fuses into the clay at over 2,000°F and becomes permanent.
You stop thinking about what your dishes are doing to your food, because the answer is nothing. That's what you should expect from something you use every single day.

Frequently Asked Questions
Is it safe to keep using dishes with hairline cracks or chips?
No — and most people keep using them anyway. Hairline cracks (called crazing) and chips break the protective glaze layer that keeps bacteria out. Once that layer is compromised, bacteria and food residue collect in those crevices in ways a dishwasher can't reach.
A crazed or chipped dish is not truly cleanable. It looks fine. It isn't. The right answer is to replace it.
M.A. Hadley stoneware is fired at 2,300°F — a process that creates an exceptionally hard, durable surface that resists crazing far longer than most commercial dinnerware.
Do ceramic dishes contain lead?
Some do. Lead has historically been used in ceramic glazes to create smooth, glossy finishes — and it's still present in older sets and in many mass-produced dishes made overseas without US safety oversight.
The risk increases with age and wear. Acidic foods — tomatoes, citrus, vinegar, wine — accelerate leaching from compromised glazes. If your dishes are more than 20 years old or were made outside the US, it's worth taking seriously.
M.A. Hadley pottery is lead-free and cadmium-free.
Are plastic and melamine dishes safe for food?
Not ideally. Plastic and melamine dishes release microplastic particles into food — and heat accelerates the process significantly. Hot meals, the microwave, and repeated dishwasher cycles all degrade the surface faster.
Studies have found microplastics in human blood, lung tissue, and organs. The older and more worn the dish, the higher the rate of particle release. This is a slow accumulation problem, not an immediate one — which is part of why it gets overlooked.
Fired stoneware has no coatings and no plastics. What you see is the dish itself — clay and glaze, fused permanently at high heat.
Is ceramic microwave safe?
Most high-fired stoneware is microwave safe — the clay and glaze don't absorb microwave energy the way metal does. The exception is ceramic with metallic accents or metallic glaze elements, which should stay out of the microwave.
When in doubt, check with the manufacturer. Any reputable American-made stoneware should tell you clearly.
M.A. Hadley pottery is microwave safe. It's also oven safe and dishwasher safe — made for real daily use, not just display.
How long should a good set of dishes last?
Mass-produced dinnerware — especially anything with coatings or printed-on decoration — typically shows meaningful wear within 5 to 10 years of daily use. The glaze dulls, colors fade, and surface integrity breaks down.
Well-made stoneware is a different category. Fired correctly and cared for reasonably, it should last decades — and then some. The people who own M.A. Hadley pieces tend to keep them for 30, 40, 50 years. Most people pass them down.
Why is handmade pottery more expensive than store-bought dishes?
Because every piece takes significantly more time. A mass-produced dish is cast in a mold, decorated by machine, and fired in a continuous kiln. A handmade piece is shaped, trimmed, hand-decorated by a person, and fired individually.
The difference shows in the result — and in the lifespan. A $15 dish replaced every 10 years costs more over a lifetime than a $75 dish that lasts 40. Handmade pottery isn't an indulgence. For most people who make the switch, it turns out to be the more practical choice.
All Hadley Pottery pieces are handmade and hand-painted.
What dishes are worth passing down?
The ones that were made to last, made to be used, and made with enough character that someone wants to keep them. Most dinnerware fails all three — it's fragile, it's purely functional, and it has no story.
Handmade pottery — especially signed, artist-made work — is the exception. It carries the memory of every table it's ever been on. That's not sentimentality. That's just what happens when an object has genuine quality and a human hand behind it.
Every M.A. Hadley piece is signed by the artist who painted it. That's not a marketing detail — it's the whole point.
