Are Clay Pots Good Or Bad For You?

Clay pots, also known as earthenware or terracotta, are cooking vessels made from natural clay baked at high temperatures. Clay is a porous material containing minerals that allows heat and moisture to circulate evenly through the pot during cooking. This makes clay an excellent conductor and retainer of heat. Clay pots have been used for cooking and food storage throughout history in many cultures around the world.

History of Clay Pots

Pottery is one of the oldest human inventions, originating before the Neolithic period. The earliest ceramic objects have been dated back as far as 29,000 BC, such as the Venus of Dolní Věstonice figurine discovered in the Czech Republic (Wikipedia).

Clay was one of the earliest materials manipulated by humans. Evidence of pottery has been found dating back over 10,000 years ago in East Asia and other regions (Deneen Pottery). Pottery allowed early civilizations to store and transport food and water safely. Over time, pottery developed cultural significance through ritual and decorative uses.

In ancient times, clay pots were essential for cooking, storage, and transport. They were used for boiling, stewing, and baking foods across many early civilizations including ancient Egypt, Greece, Rome, China, and the Americas (Lakeside Pottery). Clay’s ability to hold heat and water made it invaluable for daily life before modern materials were invented.

Pros of Cooking with Clay

Clay pots provide even and consistent heating while cooking. The thick walls retain heat and distribute it gently and evenly throughout the entire pot, preventing food from burning (https://www.veganfirst.com/article/health-benefits-of-clay-pot-cooking). This allows ingredients to cook thoroughly without scorching or developing hot spots.

Clay is also porous and breathable, allowing steam to escape through tiny pores in the clay. This moisture circulation enables food to cook in its own juices, retaining nutrients and natural flavors that would otherwise evaporate. Cooking in a clay pot infuses dishes with more moisture than other materials like metal or glass (https://mitticool.com/health-benefits-of-clay-pot-cooking/). Clay pots are especially good for braised dishes, rice, beans, soups, stews, and chilis that benefit from gentle simmering.

Cons of Cooking with Clay

While clay pots have some advantages, they also come with some drawbacks to consider. Two of the main cons of cooking with clay are that clay pots tend to be heavy and prone to breaking.

Clay is a dense, heavy material. This makes clay pots much heavier than pots made of metal, glass, or plastic. The weight of clay pots can make them cumbersome to move around and difficult to handle, especially when full of food or liquid. Their heft also makes them prone to cracking or breaking if dropped.

The porous nature of unglazed clay also means it can be more brittle than other materials. Clay pots and bakeware do not flex or bend easily without cracking or chipping. Sudden temperature changes, in particular, can cause clay to expand and contract enough to develop cracks. This risk of breaking is increased by the heavy weight of clay putting stress on the material.

So cooks need to be careful when moving and handling clay pots to avoid drops or bangs that could damage them. The potential to crack also makes clay less durable over time than some other cooking vessel materials. These cons of fragility and heaviness are important factors to weigh when deciding whether clay is right for your cooking needs.

Clay Pots vs Other Materials

Clay pots have some advantages and disadvantages compared to other common materials like metal, glass, and plastic. Here’s an overview of how clay pots stack up:

Metal: Metal pots like cast iron and stainless steel conduct heat very evenly. This allows for consistent cooking results. However, metal can react with acidic foods and impart a metallic taste. Clay is neutral and doesn’t impact flavor. Clay pots are also lighter than cast iron. However, clay is more prone to breaking. Overall, metal and clay pots both have pros and cons and serve different purposes.

Glass: Glass pots let you visibly monitor food while cooking. However, glass doesn’t retain heat as well as clay. Clay pots have superior insulation, which leads to more even cooking. Clay pots also won’t shatter like glass. But glass pots are easier to clean and won’t absorb stains like porous clay. For these reasons, glass and clay pots have complementary strengths.

Plastic: Plastic pots like Melamine are affordable, lightweight, and durable. However, they can leach potentially harmful chemicals under high heat. Plastics also lack the heat retention of clay. While convenient for storage, plastics aren’t ideal for all cooking uses. Clay is more natural and better for wet cooking techniques like braising.

So in summary, clay pots offer some unique benefits over metal, glass, and plastic options. But all materials have their appropriate uses. Choosing the right pot depends on the specific cooking application.

Tips for Cooking with Clay

There are a few tips to follow when cooking with clay pots to get the best results.

First, it’s important to properly soak and season new clay pots before using them. Soak the pot in water for at least 15 minutes before first use. This allows the clay to fully saturate and prevents cracking. Then season the pot by coating the inside with oil and letting it sit for a day. Repeat the seasoning process 2-3 times before cooking.

When heating a clay pot, bring it up to temperature gradually to prevent cracking. Start on low heat for 5-10 minutes before increasing to the desired temperature. You can also fill the pot with cold water and bring it to a boil before adding ingredients to temper the clay.

Use medium or medium-low heat when cooking in clay. The thick walls retain heat well so there’s no need for high heat. Avoid sudden temperature changes by not adding cold ingredients directly to a hot pot.

Stirring regularly will also help distribute heat evenly when cooking. Clay is not as conductively smooth as metal or glass pots.

Following these tips will lead to successful cooking experiences with clay cookware.

Clay Pot Safety

One of the main concerns with cooking in clay pots is whether they contain lead that could leach into food during cooking. Not all clay pots are created equal when it comes to lead safety. The clay type and materials used during manufacturing play a big role.

High-fired clay vessels made from natural clays are generally considered safe for cooking and consuming food. According to Miriam’s Earthen Cookware, natural clays that undergo high-temperature kiln firing do not contain concerning levels of heavy metals like lead (https://miriamsearthencookware.com/mec-blog/is-it-safe-to-cook-in-clay-pots/). The high heat causes any potentially harmful substances to burn off.

On the other hand, low-fired decorated clay pots glazed with lead-based paints or metal oxides can leach lead and other toxins into food, especially acidic foods. It’s important to buy clay pots from reputable brands that have lead-free certifications and disclose their materials and manufacturing (https://ireadlabelsforyou.com/clay-cookware-safe-or-toxic/). If a clay pot doesn’t specify “lead-free”, it’s best to avoid it.

Consumers should look for lead-free certifications from organizations like the FDA and Prop 65. Reputable clay pot brands will openly disclose their lead testing and materials used. When in doubt, perform an at-home lead test on a new clay pot before using it for cooking.

Cleaning and Caring for Clay Pots

Clay pots require proper cleaning and care to maintain their charm and functionality over many years of use. There are a few key methods for cleaning clay pots:

Soaking – To deep clean and disinfect terra cotta pots, make a solution of equal parts distilled white vinegar and water. Soak the pots in this solution for at least 30 minutes. The acidic vinegar will help remove mineral deposits and dissolve built-up salts and stains (https://www.bhg.com/how-to-clean-terra-cotta-pots-7498661).

Scrubbing – Use a stiff brush or abrasive sponge to gently scrub the inside and outside of the pots while soaking. This agitation will help loosen stuck-on debris.

Rinsing – Rinse the pots thoroughly with clean water after soaking and scrubbing. Make sure to remove any traces of vinegar or cleaning solution.

Sealing – After cleaning, apply a food-safe sealant to the outside of clay pots to help prevent mineral deposits and water stains. Reapply sealant annually.

Avoid using harsh chemicals like bleach for cleaning clay pots, as this can damage the porous clay material. With proper regular cleaning and sealing, clay pots can stay looking beautiful for many seasons.

Types of Clay Pots

Clay pots come in a variety of types, differentiated by the clay material and manufacturing process used. Some of the most common types of clay pots include:

• Terracotta – Terracotta clay is red-orange in color after firing. Terracotta pots are porous and allow air flow. They are well-suited for cooking dishes with liquid that need evaporation like stews or rice. Terracotta imparts an earthy flavor. Source

• Earthenware – Earthenware clay is fired at lower temperatures and is more porous than stoneware. It comes in natural clay colors like red, brown, and white. Earthenware absorbs liquid and moisture well. It can impart subtle flavor to dishes. Source

• Stoneware – Stoneware clay is vitrified and non-porous. It provides even heating and heat retention. Stoneware comes in natural clay colors and glazed options. It does not absorb flavors or liquids. Source

Clay pots differ from metal pots in that they provide natural non-stick surfaces, absorbent materials, and can enhance flavor. Choosing the right clay pot depends on the dish being cooked and desired results.
