Nonstick cookware saves time and allows for healthier cooking. Test your knowledge of nonstick cookware with this quiz.

What were scientists looking for when they accidentally discovered the first nonstick coating?

  • a less toxic refrigerant
  • a more powerful cleanser
  • a scratchproof cookware coating

What is the relationship between PTFE and Teflon?

  • They are the same thing.
  • Teflon is derived from PTFE.
  • They are different substances, but both prevent food from sticking to pots.

Which company trademarked the Teflon brand name?

  • DuPont
  • Tefal
  • Cookware Manufacturers Association

How long did it take for Teflon-coated pots to come on the market after the chemical was patented?

  • one year
  • 15 years
  • 25 years

What type of atom is the key to PTFE's properties?

  • fluorine
  • carbon
  • titanium

How does fluorine work on an atomic level to make PTFE into a nonstick substance?

  • by preventing carbon atoms from reacting during cooking
  • by deflecting the heat away from the pan and back onto the food
  • by creating a harder surface than metal alone has

What are some reasons that nonstick polymers other than PTFE have also been developed?

  • increased strength and improved looks
  • reduced cost and simplified application
  • increased durability and reduced toxicity

What is a common industrial use for PTFE?

  • insulation for high-voltage wires
  • coolant for refrigerators
  • coating for ball bearings

What metal is most commonly used as the base for most nonstick cookware?

  • aluminum
  • steel
  • cast iron

What is the key to getting a nonstick coating to stick to the pot itself?

  • roughening the surface of the cookware
  • increasing the friction coefficient of the pot
  • magnetizing the surface of the pot

What is one method used to put the PTFE coating onto a nonstick pot's surface?

  • Spray it on the pot.
  • Submerse the pot in it.
  • Vaporize it to the pot.

What is the final step in applying the nonstick coating to a pot?

  • baking the pot
  • polishing the pot to smooth out the coating
  • air-drying the pot for a week

Which of these affects how long your nonstick pot will last?

  • the thickness of the pot's base metal
  • the type of food you cook in it
  • the climate in which you live

How long are most nonstick coatings expected to last?

  • three to five years
  • five to seven years
  • seven to 10 years

Why should you not use a lot of cooking spray with a nonstick pan?

  • It leaves a residue that eventually stops the surface from working properly.
  • It breaks down the nonstick coating.
  • It's redundant to use cooking spray with a nonstick pan.

What temperature guideline is good to follow when cooking in a nonstick pan?

  • The pan should be heated to at least 400 degrees Fahrenheit (204 degrees Celsius.)
  • The pan should be heated to at least 500 degrees Fahrenheit (260 degrees Celsius.)
  • Don't heat the pan to hotter than 450 degrees Fahrenheit (232 degrees Celsius).

What made the Environmental Working Group try to get warning labels placed on PTFE-coated cookware in America?

  • bird deaths
  • a high number of cancer cases
  • toxic waste near manufacturing plants

What is recommended to avoid inhaling dangerous fumes while cooking with nonstick pans?

  • Stop using pans when their coatings start wearing out.
  • Use an exhaust fan when cooking with a nonstick pan.
  • Cook with a mask on.

What are the selling points of the new Thermolon nonstick coating?

  • fewer health concerns and more environmentally friendly
  • less expensive and more durable
  • longer lifespan and can be heated to high temperatures

When did Thermolon and Ceramica nonstick cookware hit the U.S. market?

  • 1993 and 2000
  • 2001 and 2003
  • 2007 and 2008
