Ceramic Coated Cookware has gained popularity in recent years as a safe alternative to Teflon. All ceramic coatings are free of PTFE and PFOA, the two ingredients that have received negative publicity recently.
The ceramic cookware with a non-stick coating promises a number of benefits to potential buyers:
- Ceramic coated cookware is non-reactive, which means you can quite safely cook any type of food in it, including acidic foods.
- Non-stick surface helps to prevent food from sticking, allowing for easy release of cooked foods.
- The ceramic coated interior surface requires less fat to keep food from sticking compared to stainless steel or cast iron cookware.
- Silicon dioxide, which is found in ceramic coatings makes cleanup is a breeze because this material repels oil and water from the surface.
- Ceramic cookware has a visually appealing finish and looks nice when displayed on your kitchen shelves. A variety of bright, decorative colors. makes this cookware attractive for serving purposes.
- The aluminum construction ensures that ceramic coated cookware is lightweight and suitable for users with weakness in their wrists or hands.
Common Complaints about Cheap Ceramic-coated Cookware
The early models of ceramic coated cookware didn’t have a high-quality coating and the performances did not fulfill buyers’ needs and expectations:
The biggest complaints about ceramic-coated pots and pans are:
- The coating is vulnerable to impacts and prone to chipping or cracking. The average lifespan of this type of cookware is up to three years with proper use and care.
- Non-stick properties tend to decline over time. Some inferior coatings are said to lose their non-stick properties after a short period of time.
- The coating can’t withstand metal utensils, so you need to use silicone or wooden spatulas and spoons.
- Hand washing is required because the strong dishwashing detergent can wear out the non-stick surface.
- Those inferior ceramic coatings have low thermal resistance and are oven safe up to 350°F.
The Next Generation of Ceramic Coated Cookware
Today, ceramic coated cookware is manufactured using a relatively new technology, which has been improving in recent years. The improvements include the following:
Manufacturers are applying more layers of ceramic, so the newer coatings are less susceptible to scratching and are able to withstand more wear over time. Consequently, newer ceramic coated cookware products have a much longer lifespan.
The newer ceramic coatings have more lasting stick resistance and can remain non-stick after years of use.
Some new product lines are made from high-quality stainless steel with an aluminum core and multiple layered ceramic interior coating. The stainless steel base makes this cookware compatible with induction ranges, while the aluminum core helps with better heat conductivity.
The new qualities also include better heat resistance. Some of the newer coatings are oven safe up to 850° F.
Some brands of ceramic coated cookware are dishwasher-safe for extra added convenience.
Most ceramic non-stick coatings are applied using a sol-gel process. The sol-gel process converts an inorganic liquid substance into a gel that then can be applied to any metal. Sol-gel coatings are generally applied either by spray or by dipping the item in the mineral gel. The next step is a high heat firing process known as curing.
There are five basic ingredients in a sol-gel coating: The binder, the “non-stick” component, the pigments, the reinforcing agents, and the carrier which evaporates when the coating is cured.
Sol-gel coatings are scratch and abrasion-resistant, have a good non-stick performance, and can withstand higher temperatures (up to 450°C/840°F) compared to PTFE or inferior ceramic coatings.
Thermolon is the patented non-stick ceramic coating based on sol-gel technology that GreenPan uses in their non-stick products. The coating is made mainly of silicon and oxygen. These pans feature excellent thermal conductivity and high scratch resistance. They are dishwasher safe, and heat resistant up to 850°.
Titanium Reinforced Interior Ceramic Coating
Titanium reinforced coating incorporates Titanium to provide extremely high resistance to scratches and chemicals. This type of coating has all the benefits of top quality ceramic coating but is multiple times harder.
The Scanpan cookware has recycled aluminum-stainless steel construction and ceramic, titanium-reinforced interior surface. The interior coating is highly scratch resistant and allows for the use of metal utensils. The metal layer on the bottom makes this cookware suitable for induction stovetops. These pans are advertised to last a lifetime.
Nano Ceramic Nonstick Coating
Nanoceramic coating consists of ceramic nanoparticles, which are glued to the cookware surface by using a special adhesive. Nanoparticles based coatings are durable, scratch-resistant, extra smooth, dishwasher safe, and will not fade or peel with repeated use.
The Flamekiss Fry Pan by Amorè Kitchenware features a nano-ceramic nonstick coating that allows for low-fat cooking. The coating remains nonstick longer than most ceramic coatings, and you can use metal utensils with it.
The problem is that nanotechnology is a completely new branch of science. It also still isn’t entirely clear how the use and disposal of nanoparticles affect the environment and human health.
Diamond coating is reinforced with real shimmering diamond crystals. This type of ceramic coating features excellent durability and exceptional non-stick properties for easy food release.
The coating of each Swiss Diamond pan contains up to 200,000 real diamond crystals. Diamond particles give the coating an extra-long lifetime, superior heat conduction and outstanding nonstick release properties. Diamond cookware is advertised to be perfect for cooking without oil, so you can trim down on calories and fat.
