How Ceramic Cookware Is Made

When we talk about ceramic cookware there are two types to mention. One is made of 100% ceramic and the other has a ceramic nonstick coating. Each has a particular process of production.

Ceramic is an inorganic (meaning no carbon) and non-metallic material that constitutes the material in the natural ceramic cookware like Xtrema. It is one of the best natural cookware materials.

In the non stick ceramic cookware type, the manufacturers use sand (silica) that is formulated to provide a non-stick surface.

How is ceramic cookware made?

Making of the non stick coating of ceramic pans

Instead of using toxic chemicals and solvents to prevent food from sticking, the ceramic nonstick pans feature a glass-like ceramic finish that is smooth with no microscopic pores in which food particles can adhere, thus making them nonstick. The finish is ultra dense and ultra hard.

Ceramic coatings include patented types, like Thermolon, used by GreenPan and GreenLife in their best ceramic nonstick cookware.

Thermolon coatings involve a Sol-Gel procedure: “Thermolon is developed from an inorganic, ceramic polymer based on silica that is coated using a sol-gel process. It is a mineral-based coating made primarily out of a combination of silicon and oxygen – the same basic elements found in sand. Thermolon’s inorganic origins allow it to overcome environmental and engineering inefficiencies found in organic non-stick coatings such as PTFE.” (Porcelain Industries 2018)

From the manufacturers (e-mail: [email protected]) of Thermolon:

Thermolon™ is inorganic (i.e., mineral in origin) and, therefore, offers a unique combination of properties:

Hardness (up to pencil hardness 9H)

• High heat resistance (up to 450°C)

• Low coefficient of friction

Patented Weilburger Greblon® ceramic nonstick coating used by Healthy Legends also uses the Sol-Gel technology, which is a process that converts the inorganic solution into a gel that is applied to a metallic base by spraying or dipping and then hardened by firing (known as curing).

Weilburger claims their product contains no lead, no cadmium, no PFOA, and no PFOS (Perfluorooctane sulfonate, another PFAS).

The nano-ceramic technology used in Cuisinart ceramic cookware and by other cookware companies also involves the Sol-Gel technology.

Making of the 100% Ceramic Cookware

This 100 percent ceramic cookware is made of molded natural clay and finished with a natural ceramic glaze.

The Xtrema Range contains no metals or toxic substances, according to the manufacturer. It makes it one of the healthiest cookware – good for your health and the environment…

It takes 20 days to complete the making of this pure ceramic cookware. It’s made of light-weight pressure cast ceramic. 

Each piece is cast in a mold under high pressure and then triple-fired at extremely high temperatures (2,500ºF) for strength and durability.

Staub is another 100% ceramic cookware range and this video displays the making of this pure ceramic cookware.
