Cast Iron Basics

“Cast Iron”
This article on provides an overview of cast-iron cookware.

“Numbers & Letters”

Cast Iron Info has tons of great info on cast iron, its history, how to restore it, and more.

“Lightweight Cast-Iron Skillets”
The folks at spent some time experimenting with lightweight cast-iron cookware. You’ll have to subscribe to their site to see their top picks, but the last line of the article sums up their results: “Lightweight cast iron proved a disappointment.”

Wagner & Griswold Society
Even if you don’t have an old Wagner or Griswold pan, you’ll still find lots of helpful and interesting info on the website for the Wagner & Griswold Society.

Manufacturers & Accessories

Lodge Manufacturing
The oldest manufacturer of cast-iron cookware in the US, Lodge continues to provide budget-friendly cookware and bakeware in a variety of styles and sizes. They also carry carbon steel and stoneware pieces as well as enameled cast iron. Their site also has some helpful tips and videos about caring for cast iron and enamelware.

Le Creuset
Le Creuset changed the cooking industry when they began manufacturing beautiful, colorful enameled cast iron in 1925. While their price point is higher than Lodge’s, they have many more choices in colors and styles.


“3 Ways to Clean a Cast Iron Skillet”
In this video from, guest blogger Erica provides three ways to clean a cast-iron pan. In the third method, she uses steel wool to scour the pan, which I don’t recommend at all. Steel wool will remove the seasoning from you pan! Instead, use a silicone scraper or a stiff brush. You can also heat water in the pan to loosen up baked-on food.

“How to Clean Your Cast Iron”
I love Paula Deen, but I don’t agree with this video from In it, we’re instructed to never use soap and water because it will make the pan rust. Instead, we’re shown three ways to to clean the pan: 1) bake off the gunk, 2) wipe it off with oil; or 3) use salt to scrape off food. While it’s true that water will cause cast iron to rust, a simple light seasoning on the stove will resolve that. Oil and salt can certainly be used to “unstick” that stuck-on food, but baking the pan for an hour after each meal is unnecessary. Also, please note that rubbing a cold pan with oil does not constitute seasoning; the oil must be heated to create that nonstick coating. All-in-all, this video is fine for chefs but not for busy homecooks.


“Chemistry of Cast Iron Seasoning: A Science-Based How-To” has some good info on seasoning cast iron. This article outlines the science behind seasoning and explains why flaxseed oil is the best kind of oil for seasoning. While the author’s recommendation is sound, she says the pan should be coated in flaxseed oil and then baked bake at 500 degrees F for an hour. That temperature is way above the oil’s smoke point, which would cause toxic fumes to be released into the air. That’s why I suggest baking the pan at a temperature commensurate with the oil’s smoke point.

Health Benefits

“Iron: Fact Sheet for Health Professionals”
This fact sheet by the Office of Dietary Supplements (ODS) provides in-depth information on iron. I particularly like the nifty chart that provides the Recommended Dietary Allowances (RDA) for Iron. (A man 19-50 years old should receive 8 mg while a woman of the same age should receive 18 mg!)

Iron Infographic
This infographic on shows how Ferric iron (what you get from eating out of cast-iron cookware) is converted to Ferrous iron, which the body can use.

This article from lists different ways you can mitigate toxins in your kitchen, such as avoiding chemical nonstick cookware and looking for high-quality stainless steel.

“Is Your Cookware Damaging Your Health?”
This article from lists three types of cookware to avoid: chemical nonstick, aluminum, and copper. It also links to studies that address aluminum and its link to Alzheimer’s.

Chemical Non-Stick Cookware

“What is PFOA?”
This article on WebMD explains what PFOA is and how it can negatively affect your health. Even though most companies have now stopped using it, similar chemicals are taking its place.

“The EPA Doesn’t Want Americans to Know How Dangerous Teflon Chemicals Are”
This 2018 article from points to a report released by the CDC that states chemicals from the PFA family (which are used in chemical non-stick cookware among other places) are far more dangerous than previously believed.

“Teflon Replacement on Track to Test Definition of Hazardous Chemicals”
This article from (the new name for Mother Nature Network), explains the new chemical used in place of PFOA might be just as dangerous because it accumulates in our water supply.

“Is Nonstick Cookware Like Teflon Safe to Use?”
This article on provides good recommendations on how to use and care for chemical nonstick pans in a way that reduces your exposure to harmful chemicals. However, I disagree with the author’s assessment that modern-day nonstick pans are safe to use when used properly because research indicates these chemicals may be just as dangerous.

“Teflon Dangers in Nonstick Cookware and a Better Alternative”
In this article on, the author details the health concerns with PFOA (which is no longer used by most cookware manufacturers). She suggests using pans with ceramic coatings, which do not emit fumes or leach chemicals. While these pans have their limits (don’t put them in the oven!), they can be a nice alternative to chemical nonstick pans. Personally, I prefer cast iron.

“Is Nonstick Cookware Safe? Here’s Everything You Need to Know, According to the Experts”
The ever-helpful folks at tested several chemical non-stick pans to see if they reached the heat threshold of 500 degrees F. This article lists the concerns over using the pans but also provides tips if you’re not willing to give them up (yet—I mean, did you read the articles above?).

This study published by the American Chemical Society in 2013 states, “Stainless steel cookware can be an overlooked source of nickel and chromium, where the contribution is dependent on stainless steel grade, cooking time, and cookware usage.”

“Stainless Steel: All About Food Grade 304, 18/8 and 18/10”
This article from the outlines the differences between the different grades and series of stainless steel. The author states stainless steel is safe when the right grades are used appropriately.

“Does Stainless Steel Leach Chemicals”
This article from states that stainless steel leaches nickel and chromium but in amounts to minimal to be of concern (which some may disagree with). However, she lists cast iron and enameled cast iron as other safe cookware options.

Ceramic Cookware

In this article from, the author lists four reasons why you shouldn’t use (or at least be careful using) cast iron on a glass-top stove, including the risk of scratching the surface or having too much weight on the glass. While this may be true for older models of glass-top stoves, I’ve found other sources that indicate cast iron is fine on new models as long as they’re not dragged on the surface and the stove’s weight limit isn’t exceeded.
