What is Hard-Anodized Cookware
Hard-anodized cookware is made from aluminum which is then coated in a non-stick oxide layer to ensure no contact between the aluminum cookware and food. This anodized layer is both hard and durable, reducing any chance of contamination through exposure to aluminum.
What is Ceramic Coated Cookware
When discussing ceramic cookware, one needs to distinguish between 100% ceramic cookware (made from clay also known as earthenware) and ceramic-coated nonstick cookware.
The type we are talking about in this article is ceramic-coated nonstick cookware.
What most people do not realize is that ceramic cookware is most often also made from aluminum. A ceramic coating is relatively hard, but it can crack or chip under certain conditions, allowing for possible contamination.
Then there is the hard anodized nonstick ceramic cookware. Technology innovatively meshes materials we have on hand that are tried and true and bring us more options every day.
Example 1 – Nonstick Ceramic Coated Aluminum Cookware
Example 1: is a GreenLife Pro Ceramic Nonstick Aluminum Skillet it’s core aluminum. Its interior has a nonstick ceramic coating that is free of PFAS, PFOA, lead, and cadmium. Can be used on all stovetops but not induction the stainless steel handles and rivets make it oven safe up to 600°F.
Example 2 – Nonstick Ceramic Coated Hard Anodized Cookware
Example 2: is a GreenPan Paris Pro Hard Anodized Ceramic Nonstick Fry Pan its body and core are hard anodized aluminum. Its interior has a Thermolon nonstick ceramic coating that can withstand metal utensils. To finish a quality build it has stainless steel handles and rivets making it oven and broiler safe up to 600°F.
Materials Used in Producing Anodized and Ceramic Cookware
Aluminum is an excellent material to use for cookware based on how well it conducts heat. It is also lightweight and recyclable. It fell out of favor for use in cookware due to its health risks. Aluminum is a neurotoxin linked to diseases of the central nervous system such as Alzheimer’s and ALS.
Since medicine found this link, many people have tried to avoid using aluminum in cookware altogether. Science has, however, allowed new production techniques to make it a safe cooking option again. Coating the aluminum makes it possible to use it for its excellent heat distribution qualities without direct contact that can cause leaching into the cooked product.
Materials and Methods Used to Coat the Cookware
If both products have aluminum as the base material, it seems then that we should be looking at the coating to differentiate between the health risks of each.
The coating and the method used to coat the cookware differ and lend each type of different cookware-specific characteristics.
With anodized cookware, an electrochemical process is used to bond an oxide layer to the aluminum pot. This layer is tough and makes anodized cookware stronger than stainless steel. Hard anodized cookware is durable and able to withstand cooking at high to very high temperatures. It does not readily chip or scratch.
Ceramic cookware has a layer of material such as silica dioxide bonded to the cookware at a very high temperature by firing. This forms a smooth glass-like surface for this type of cookware.
The ceramic layer needs more care when used to avoid chipping and cannot withstand very high temperatures. Chipped surfaces allow the leaching of the base substance into the food. Substances like lead and cadmium are sometimes used in the glaze when the ceramic coating is fired in the kiln. The release of such chemicals is a risk if the coating layer is damaged.
Tip: Research the labels, materials of the cores and the coatings, and where the cookware is made… You are looking for PFOA and PTFE chemical-free cookware.
Which Product Is Safer, Hard Anodized, or Ceramic Coated?
Many factors should be considered when answering this question. There is a lot of research done on all these factors, yet there is no straightforward answer.
Some of the factors that affect the safety of use include:
- Materials used in producing the cookware
- Materials and methods used to coat the cookware
- At what temperature do you cook?
- What utensils do you use when cooking?
- The method used to clean your cookware
At What Temperature Do You Cook?
As a rule, nutrition is best preserved when we use medium heat for cooking. Aside from searing a steak or stir-fried dishes, most household cooking can be done at a medium heat range.
Industrial kitchens and professional chefs tend to cook at higher temperatures. Hard anodized cookware is favored in this type of cooking environment. It can function in high heat with no ill effects.
Tip: No cookware is really non-stick use some healthy oil or other liquid when frying, searing sauteing, or browning. It will also protect the surface of your cookware and make the cleanup easier.
Ceramic cookware is ideally suited to a medium-heat style of cooking. Even though it can withstand higher heat, it is not advised. Applying extreme heat and then cold could lead to damage which could render your cookware useless.
What Utensils You Use When Cooking
As exposing the base material of your cookware can increase the risk of leaching and contamination, it is essential to reduce this exposure.
The anodized coating is scratch and chip-resistant. As such, metal utensils are fine for use. The coating does not easily get scratched, which would cause it to lose its stick-resistant nature.
The use of metal utensils is definitely not advised for ceramic cookware. It can easily take on scratches. It could also cause chipping under certain conditions. Silicone or wooden utensils is best recommended for ceramic cookware.
Method Used to Clean Your Cookware
Dishwashers are convenient, but some items just should not be washed in them. Pots and pans fall in this category as a general rule.
Hard anodized is easy to wash and clean due to its smooth, stick-resistant nature. Scorched food can be removed with a nylon brush or nylon scrub pad. More stubborn residue can be soaked with regular dishwashing detergent and hot water.
Anodized cookware is easy to clean and seldom requires more than mild liquid soap and a soft sponge. Most manufacturers indicate that hard anodized cookware is dishwasher safe. To ensure the longevity of the coating, it is still not advised.
Ceramic cookware has a smooth surface, and food should generally wash off easily with only mild liquid dish soap and a soft sponge. It is essential always to allow your ceramic cookware to cool down before washing it, as this type of cookware does not respond well to sudden or extreme changes in temperature.
If the cookware was used at high heat or incorrect utensils have been used, scratches can develop on the surface that would cause food to stick more and make washing harder. Over time the surface can discolor and draw into the coating.
Unless there are deep cracks or chips, the cookware should still be functional. Never wash ceramic cookware in a dishwasher, as the harsher chemicals will break down the coating sooner.
Safety of Hard Anodized vs Ceramic Cookware
Production regulations and guidelines are in place to protect consumers from the many known dangers associated with both types of cookware. This is best regulated in the United States and European Union countries. If your cookware is produced in one of these countries, it is safe to assume all guidelines were followed.
If you are uncertain of the country of production, additional concerns could arise. Both types of cookware could have Teflon or other non-stick coatings. This could add chemicals like PTFE and PFOA to the list of concerns and increase the possibility of exposure to lead and cadmium used in glazes. It is best to do your homework regarding the manufacturer and check all ingredients used as best you can before you invest.
