How Do Ceramic Cooktops Function?

Any cooktop made of tempered ceramic glass with a smooth surface is a ceramic cooktop. Though you'll usually find all ceramic smoothtops lumped together on the sales floor, there are actually a few different options to pick from:

Radiant uses heated coils of metal under a sheet of ceramic glass
Halogen uses halogen bulbs instead of metal to generate heat
Semi-halogen uses a combination of metal coils and halogen bulbs
Induction uses magnets, which interact with the metal in your cooking pans, to generate heat

There are just small differences between the first three models. Halogen bulbs light up right away, so you always know when the cooktop is on, and the heating elements tend to cool off a tiny bit faster compared to radiant cooktops. Other than that, they all cook the same and offer all the same conveniences.

On the other hand, induction cooktop works differently. These cooktops are very fast to heat, and boil water twice as quickly on average compared to other cooktops. That's because it doesn't use a heat source to transfer heat to the pan like a traditional cooktop -- instead, the interaction between magnets and metal heats the pan directly, effectively turning the pan into a burner. That means that the cooktop won't heat up until you put a pan on it, even if the power is on.

Pros Of Using Ceramic Cooktop

At first, with ceramic cooktops, cleaning is a breeze. The smooth, sealed heating elements make it easy to wipe up spills with just a damp cloth or soft sponge -- no more metal grates collecting oil!

With most of ceramic cooktops, cooking is made much easier and more safe. Many have heat indicators that show when the stovetop is hot, and induction cooktops don't even heat until a pan has been placed on them. Some ceramic cooktops even turn off automatically after a set period of time -- which means curious kids are less likely to get hurt when helping out in the kitchen. Ceramic cooktops also eliminate the need to run potentially dangerous gas lines through your kitchen -- all you need is an electrical connection to make them work. The reduced risk of gas leaks can make your whole home much safer in the event of an earthquake, storm, flood, or fire.

Cons Of Using a Ceramic Cooktop

A good thing about ceramic cooktops is that there are almost no cons of its usage.

The biggest concern of using a ceramic cooktop for many is a scratched glass. Rough-bottomed pans or dropped items can potentially scrape or even crack the surface -- but the ceramic glass of your cooktop is tempered and built to withstand heavy use, so you'd have to drop something pretty heavy to actually break it.

Also, there could be a bit less precision and slower heating when it comes to radiant and halogen cooktops. Most professional chefs prefer the uniformity that flame cooking offers. However, if you're looking for truly professional cooking like you can get on a traditional gas burner, induction offers a solution for those weak points that other ceramic cooktops struggle with, offering speedy, powerful heat output and precise temperature control.

The other downside of induction cooktops is that not all the types of pans and pots will work with the magnetic cooking technology. So if you're thinking about getting an induction cooktop, be aware that you may have to invest in some new cookware as well.

Ceramic cooktops have a smooth and flat surface that is made from ceramic glass. Stores tend to group all ceramic cooktops together.

However, there are multiple choices:

The cookware becomes the heat source and the cooktop will not heat up until you place a pan on it. Induction cooktops are becoming increasingly popular because they are highly efficient, easy to clean, and can reach a boil or drop in temperature quickly. This can result in a faster cooking process, especially when water is brought to a boil quickly.

Here are some pros and cons to think about when deciding whether a ceramic cooktop is right for your kitchen. 

The advantages of ceramic

• The easy cleaning of ceramic cooktops makes them an excellent alternative to gas stovetops. Gas cooktops have grates and burners which need to be removed for cleaning.  Meanwhile, ceramic cooktops are completely smooth, so oil cannot accumulate on them.
• Many radiant cooktops have heat indicators that show when the stovetop is heated, and induction cooktops do not heat until a pan is placed on them.
• They look amazing in any kitchen!   Ceramic cooktops blend in beautifully with their surroundings, as an increasing number of appliances are becoming seamlessly integrated.

Induction also offers the following advantages:

• Improved cooking results due to better temperature control.
• Improved efficiency can tend to result in faster cooking times. The Department of Energy reports improved efficiency as 85% of the energy arrives directly to the cookware with induction ranges.
• The hot air generated in the kitchen is reduced when using induction cooking.
• An instant response to a temperature change.
