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 which have received negative publicity recently.
The new non-stick cookware coatings promise 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 getting stuck and can be easily cleaned. Ceramic coated interior surface requires less fat to keep food from sticking compared to stainless steel or cast iron.
- 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 comes in a variety of bright, decorative colors. This type of cookware is attractive for serving meals and looks nice when displayed on your kitchen shelves.
- The combination of the aluminum construction and ceramic coating makes for a lightweight and ergonomic pan, perfect for users with weakness in the wrists or hands.
Common Complaints about Cheap Ceramic-coated Cookware?
The early models of ceramic coated cookware did not have a high quality coating and its’ performances did not fulfill buyers’ needs and expectations:
The biggest complaints about those inferior ceramic-coated pots and pans are:
- The coating is vulnerable to impacts making it prone to chipping or cracking. The average life span of this type of cookware is around 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 using for a short 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 dish washing detergent can wear out the non-stick surface.
- Those inferior ceramic coatings have low thermal resistance and are oven safe up to 350°F.
Next Generation of Ceramic Coated Cookware
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 wear better over time. Consequently, newer ceramic coated cookware products have a much longer lifespan.
The newer ceramic coatings have more lasting stick resistance and remain non-stick after many years of use.
New products 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 include better heat resistance. Some of the newer coatings are oven safe up to 850° F.
There are some brands with a dishwasher safe coating for extra added convenience.
Most ceramic non-stick coatings are applied using a sol-gel process. The sol-gel coating is a process that converts an inorganic liquid substance into a gel that can be applied to any metal. Sol-gel coatings are generally applied either by spray or dipping the item in the mineral gel followed by a high heat firing process known as curing.
There are five basic elements that make up a liquid 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, has a good anti-sticking performance, and can function at higher temperatures (up to 450°C/840°F) compared to PTFE or inferior ceramic coatings.
What is Thermolon?
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 scratch resistance. They are dishwasher safe, and heat resistant up to 850°.
Titanium Reinforced Interior Ceramic Coating
Titanium reinforced coating incorporates Titanium, giving it extremely high resistance to scratches and chemicals. This type of coating has all benefits of top quality ceramic coating, but is many 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 the use of metal utensils. Metal layer on the bottom of the pans makes them suitable for induction stove tops. These pans are advertised to last a lifetime.
Nano Ceramic Nonstick Coating
Nano ceramic coating consists of ceramic nanoparticles, which are glued to the cookware surface with the help of 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 which allows cooking with little or no oil, stays 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 still isn’t entirely clear how the use and disposal of nanoparticles affect the environment and the human health.
Diamond coating is reinforced with real shimmering diamond crystals. This type of ceramic coating features excellent durability and exceptional non-stick capability for easy cooking and cleaning.
Swiss Diamond cookware
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 and an easy way to trim fat and calories from every meal.
