In most cases, tri-ply bottom cookware means just that - three ply material is used on the bottom of the cookware. Let's look at a pan and check it out. An aluminum pan is usually one ply. It's all aluminum. It's a good conductor of heat, and it works well. Some pans are copper on the bottom but have a stainless steel body (and interior). The copper and stainless make a two-ply construction. The copper conducts heat well (several tens of times better than stainless), and the stainless makes for an inert and long-wearing cooking surface. In try-ply, we usually see a stainless pan, a fat copper "disk" on the bottom, and another layer of stainless over the copper (which "seals it in" there). These pans are all stainless on the outside and inside. Stainless steel is extremely tough and resistant to corrosion. They wear forever. But stainless isn't a good conductor of heat. That little disk of copper sandwiched in between the stainless layers on the tri-plybottom makes the pan heat more quickly and cook more evenly.
The Calphalon Tri-Ply cookware has precision crafted for premium performance. This cookware has flared rims for easy pouring and an aluminum inner core for superior heat conductivity.

On a gas range, any cookware is good. You want a pan that will conduct the heat efficiently to prevent wasting energy. Just about any cast iron or annodized aluminum pan will be efficient. Stainless steel cookware should be be full tri-ply (also called all-clad pro-clad, etc). Standard stainless steel has the conductive metal only on the bottom, thus heat from a gas range would not enter through the sides of the pan. Try-ply stainless has the conductive metal on the bottom and the sides and allows good heat conduction.
Calphalon Tri-ply, Calphalon Contemporary stainless Steel, and Emeralware Pro-Clad are all really good.

Aluminium-base takes longer time to heat up but retains cooking temperature longer while copper-base is quickly in heating up and cooling down.the disc thickness for better heat conductiontri-ply stainless steel cookware (Please keep in mind that the more layers of metals in the cookware, the thicker and heavier the pot or pan is, and the more expensive the price it tends to be).

The copper bottom is more for looks than actual purpose. Some beleive the copper bottom provides more even heating.

To be authentic Magnalite by Wagner, the bottom of the cookware will bear the following stylized trademarks: "Wagner Ware" (WagnerWare) or "GHC" plus "MAGNALITE"
When choosing cookware with a thick bottom for even heat distribution, look for materials like stainless steel or copper, which conduct heat well. Check for a flat bottom to ensure good contact with the heat source. Additionally, consider the weight of the cookware, as heavier pots and pans often indicate thicker bottoms that distribute heat more evenly.
There is no standardized symbol. Most newer pans will actually have "suitable for induction" or something of that aspect on the bottom of the cookware. An easier way is to bring a magnet, yes, an ordinary refrigerator magnet with you when you shop for cookware. If the magnet sticks to the bottom of the cookware, it's metallic compound is magnetic, so that cookware will work. Since induction technology is based on electromagnetic energy transfer, a pan that attracts a magnet will work. Andrea, 23. Oregon
