There are jagged peaks and valleys. So when one places non-induction cookware on the converter disc, these imperfect metal surfaces trap countless microscopic pockets of air between them. Air, as we know, is a bad conductor. So as magnetic waves penetrate and start inducing a current, the converter disc tries to transfer the heat to the cookware.
But the pockets of air slow down the transfer. What happens consequently is that the converter disc becomes hotter than the cookware bottom due to heat build-up. Some of the built-up heat is conducted downward into the ceramic and some get transferred to kitchen air. A study was done with a converter disc made of stainless steel. Water was boiled on an induction cooktop with no converter disc and simultaneously water was kept to boil on induction with converter disc.
The result showed it took 8 minutes 40 seconds to boil 8 cups of water in induction cookware and it took 19 minutes using a converter disc on non-induction cookware. Also, after 10 minutes and 30 seconds passed, the induction on which the converter plate was kept started throttling from watts to watts.
This could be perhaps because converter disc was heated up for so long and that affected the ceramic and insulation layer underneath and also affected the coil beneath heating it up. One trick I found amusing while researching was on an uploaded video on youtube.
In the video, they used a sheet of netted steel which is usually used on windows and doors and is available in the all-purpose hardware tool shop. They double folded the netted steel sheet and placed it in on the cooktop. The non-induction cookware was placed over the sheet and the power was switched on. Since induction technology uses the power of magnetism, the cookware piece itself must be magnetic and have a flat bottom.
For this reason, cookware made from aluminum, copper or glass, including Pyrex will not work on its own. Induction cookware must be made of a magnetic-based material, such as cast iron or magnetic stainless steel.
If you're not sure if your cookware will work with induction cooktops, try sticking a magnet to your cookware. If it sticks, it should work; if it doesn't, most likely it is not induction compatible.

For fast cooking, stainless steel-layered bases are best — they heat up quickly and react quickly to changes in the temperature setting.
These pans tend to have a thinner base, and if you don't keep an eye on things they could be more prone to burning, overcooking and sticking unless it's a non-stick pan. These pans are ideal for boiling water and steaming. Skip to content Skip to footer navigation. Top of the content. How to buy the best pots and pans for induction cooking Get the most out of your induction cooker with the right cookware.
Rebecca Ciaramidaro. Your cooking style makes a difference. Induction cooktops are also easy to clean and safer to use.
The coil in the induction cooktop transfers heat directly to the pan while the surface stays relatively cool. A smooth glass-ceramic induction cooktop gives any kitchen a sleek look, too. Glass-ceramic also resists scratches and is strong enough to take impacts and temperature changes without cracking, warping or breaking.
For pots and pans to be compatible with an induction cooktop they must be made of a magnetic material: either iron or iron-based, such as steel.
Induction heating works by exciting the iron atoms in cookware, so there needs to be enough iron in your pots and pans for the heat to happen. You can also check the underside of your cookware for the induction logo. For example, some stainless-steel pans with too much nickel content react magnetically but may not work at all on an induction hob. Cookware made only from glass including Pyrex , aluminum or copper will not work on an induction hob. However, some cookware manufacturers offer aluminum or copper pans with a magnetized base that is specifically designed for induction cooktops.
The interiors of these pans are heavy-gauge die-cast aluminum with a magnetized base for the rapid-heat transfer of an induction stove. Interior surfaces can be a non-stick coating derived from stone, hard-cost anodized, or other types of coatings. Thanks to their all-iron composition, cast iron pots and pans have the magnetic quality induction hobs needs.
But is cast iron the best cookware for induction cooktops? Cast iron is also heavy.
