What You'll Learn
Calphalon's history with anodized aluminum
Calphalon was founded in 1963 by Ronald M. Kasperzak under the name Commercial Aluminum Cookware. The company originally supplied the restaurant industry and other professional food services with high-quality cookware. In 1968, Kasperzak invented hard-anodized aluminum cookware, a process adopted from the aerospace industry. This innovation made cookware more durable and resistant to corrosion and warping. The invention also turned the colour of raw aluminium from silver to "Calphalon" grey and sealed the surface of the metal, making it virtually nonporous. This nonporous surface is smooth, yet allows food to temporarily adhere while cooking. As food reaches the ideal degree of "doneness", it releases itself from the hard-anodized surface. This process also makes the cookware stick-resistant, scratch-resistant, and safe for use in ovens and broilers.
Due to the popularity of their cookware, in 1992, Commercial Aluminum Cookware changed its name to Calphalon. The company's portfolio includes a wide variety of cooking surfaces, styles, and sizes, giving chefs the flexibility to select the best cookware for their needs.
Calphalon's hard-anodized aluminum cookware was initially embraced by the professional culinary community, and it soon developed a cult-like following among non-professional, at-home gourmet chefs. In the mid-1980s, the company began marketing its products to cooking schools and small specialty gourmet stores. Today, Calphalon is a leading producer of premium-quality cookware, bakeware, cutlery, and appliances for both home and professional chefs.

Aluminum leaching concerns
Calphalon uses high-quality materials, such as hard-anodized aluminum, that are known for their excellent heat conductivity and versatility. While there have been concerns about aluminum leaching from Calphalon pans, these worries appear to be unfounded.
Some people have expressed fears that using aluminum cookware could lead to aluminum leaching into food and, consequently, cause health issues such as dementia or Alzheimer's. However, according to an environmental engineer and scientist on Reddit, there has never been a single case of aluminum poisoning from using regular, non-anodized aluminum cookware. Similarly, doctors are much more concerned about genetics and family history when it comes to dementia and Alzheimer's, rather than cookware. Furthermore, the American Cancer Society has stated that there are no proven risks to humans from cooking with non-stick pans, including those made by Calphalon.
That being said, it is worth noting that Calphalon's non-stick coating is PTFE-based, which used to be made with a chemical known as PFOA, linked to known illnesses and health concerns. However, since 2013, PFOA has been removed from the non-stick manufacturing process, and Calphalon's PTFE is now completely PFOA-free. As long as you don't overheat PTFE-based non-stick pans above 536°F, as this can release harmful fumes, and avoid scratching the cooking surface, your pan should be perfectly safe to use.
Additionally, research suggests that the amounts of chromium and nickel that could enter your food from Calphalon cookware are minimal and nothing to worry about for most people. However, those with severe nickel allergies may want to consider using nickel-free cookware.
In conclusion, while there may be some valid concerns about the safety of non-stick coatings in general, there is no evidence to support the claim that Calphalon's aluminum pans are unsafe due to aluminum leaching. As always, it is important to follow the manufacturer's care and usage instructions to ensure the longevity and safety of your cookware.

Calphalon's non-stick coating
Calphalon offers a range of non-stick cookware, including pots and pans of various sizes, with lids. The non-stick coating on Calphalon cookware is created through hard anodization, a process that converts the surface layer of the aluminium into a harder, more corrosion-resistant form, resulting in a durable, non-stick finish. This hard-anodized non-stick coating is scratch-resistant and allows for easy food release and cleanup.
In addition to the hard-anodized non-stick coating, Calphalon also offers a ceramic non-stick coating on some of its cookware. The ceramic non-stick coating is also PTFE- and PFOA-free and is infused with oil, resulting in superior non-stick properties. This type of coating is designed for everyday use and delivers consistent results, making it ideal for browning, searing, and sautéing.
It is worth noting that while Calphalon's non-stick coatings are durable, proper care is necessary to maintain their performance. For example, it is recommended to avoid using metal utensils or abrasive cleaning tools that may scratch or damage the coating. Additionally, while anodized aluminium cookware is generally safe, it is advisable to avoid storing acidic foods in bare aluminium cookware for extended periods, as it may react with the metal.

Heat management and warping
Calphalon offers a range of cookware, including pans, made from different materials such as aluminum, stainless steel, and hard-anodized aluminum. While Calphalon aluminum pans have their advantages, they are susceptible to warping due to their material properties and require careful heat management to maintain their shape and functionality.
Aluminum pans, including those from Calphalon, are known for their excellent heat conduction, allowing them to heat up quickly and evenly. However, they may not retain heat as well as other materials, such as stainless steel. This can result in uneven heat distribution, causing certain areas of the pan to expand and contract at different rates. When subjected to rapid and extreme temperature changes, aluminum pans are more prone to warping.
To prevent warping in Calphalon aluminum pans, it is crucial to manage heat effectively. Avoid heating the pan too quickly or exposing it to extreme temperatures. Always allow the pan to heat up gradually and ensure that the heat is distributed evenly across the entire surface. This can be achieved by ensuring the burner is proportional to the size of the pan, preventing concentrated heat in the center.
Additionally, it is recommended to avoid placing hot pans directly into cold water, as this sudden temperature change can cause thermal shock and lead to warping. Similarly, refrain from storing acidic foods in aluminum pans for extended periods, as this can cause corrosion and potentially impact the pan's structural integrity, making it more susceptible to warping.
By following these heat management guidelines and understanding the characteristics of aluminum cookware, you can effectively prevent warping in Calphalon aluminum pans and extend their lifespan.

Cleaning and storage
Calphalon pans are made of hard-anodized aluminum, which has been treated to make it corrosion-resistant and non-reactive to acidic ingredients. This treatment also makes the metal durable, giving it an even-heating, smooth cooking surface.
Before the first use of your Calphalon pan, hand-wash it with warm, soapy water and dry it thoroughly. Use a liquid dishwashing detergent and a non-abrasive sponge or a soft-bristle brush. Avoid using bleach or citrus-based detergents as these can damage the pan and void the warranty.
After cooking, let the pan cool down completely before washing. If your pan is dishwasher-safe, you can place it in the dishwasher, using the same type of detergent as mentioned above. If not, hand-wash the pan as you did before its first use.
When stacking pans for storage, place a paper towel, napkin, or trivet in between each pan to protect the non-stick interior from scratches and damage. Always store your pans in a cool, dry place, away from the sink or stove, to prevent exposure to water or steam, which can cause rust.
