The Calphalon Unison is a collection of non-stick cooking utensils. The Calphalon Signature meanwhile is a more extensive collection of both stainless steel and non-stick cookware pieces.

It’s worth noting that the Signature collection was introduced in order to gradually replace two of Calphalon’s cookware sets: the AccuCore and the Unison.

To ensure even heating, good conductivity, and durability, the Calphalon Unison line undergoes a thorough process, in which its heavy-duty aluminum material is hard anodized.

This material also makes sure that the entire collection is easy to wash and perfect for dishwashers.

Being a non-stick cooking set, the interior is made of a three-layer coating completely free of PFOA.

This makes your food safer and healthier to eat, and even if you don’t grease your pans before cooking, the food won’t stick to the sides and the bottom of the pan.

The Calphalon Signature non-stick line is constructed in the same manner. It is made from hard-anodized aluminum and has three layers of PFOA-free coating. Its stainless steel line, however, is far more superior.

While the non-stick line has a single metal, the stainless steel collection uses two different kinds of metals forged into five layers.

The exterior of the stainless steel line boasts a non-porous stainless steel, with three layers of aluminum in the middle to ensure fast and even cooking.

The handles of both Calphalon collections are made from cast, brushed stainless steel, which means it will stay cool while you’re cooking.

Appearance and Design

It’s easy to differentiate the Unison from the Signature from the looks alone. The Unison collection all have curved sides and wide, flat bases.

The Signature line, on the other hand, has straight sides. Because the sides of the Unison are sloped, you will find it easier to transfer contents, flip, or toss the food.

Both lines sport a modern, aesthetic look, perfect for kitchens with a contemporary design.

Non-Stick Features

The Calphalon Unison is well-known for its two non-stick surfaces: the Slide Non-stick and the Sear Non-stick. The Slide feature is responsible for releasing food instantly, while the Sear feature can be used for braising, sautéing, searing, and browning of foods.

The Sear non-stick feature is more textured and feels rougher than the Slide. This makes sure that flavor of the food is sealed.

The Signature line, meanwhile, only has the Sear Non-stick surface to ensure that your food’s natural flavor is retained through the cooking process.

While this is a good feature of the Signature, the lack of the Slide surface means that you only get to sear, brown, simmer, deglaze and sauté your food.

If you want to make pancakes and omelets without the hassle of stickiness, you may have to buy another Cookware set similar to the Unison collection.

Utensil Use

As with other non-stick cookware sets in the market, the Unison non-stick collection can only be used with wooden and nylon utensils.

This will preserve the surface of the pan, considering metal can cause scratches on the surface and eventually remove the very important non-stick coating.

With the Signature collection, however, you can use utensils of any material including metal. This durability is one of the many edges of the Signature set from the Unison set.

Oven and Dishwasher Use

The beauty of Calphalon is that all its sets are oven- and dishwasher-safe. From a general standpoint, however, non-stick pieces are best washed manually in order to prolong its usability.

You will not encounter problems with the Signature set, as they can withstand the effects of dishwashing, and they are also broiler-safe.

Induction Compatibility

As with all non-stick products, the Calphalon Unison collection will not work with induction cooktops and can only be used on electric and gas ranges.

The Signature collection’s stainless steel line, however, can be used in induction ranges and stovetops. It’s non-stick line, like the Unison, will only work in electric and gas ranges.


The Calphalon Unison cookware set is renowned for having two impressive surfaces that can cook food evenly and retain its natural flavor. This collection will only deliver on gas ranges and won’t work on induction cookers.

The Calphalon Signature’s stainless steel and non-stick lines are a favorite among professional chefs and home cooks.

This collection offers cooking variability in a wide range and can be used on both electric and gas ranges, and not limited to nylon and wooden utensil use alone.

Calphalon Unison Pros and Cons


Calphalon Signature Pros and Cons



There are many benefits to using either the Calphalon Unison or the Calphalon Signature set, but your choice should depend on your cooking style and your budget.

The Unison collection is perfect for home cooking, encompassing a wide range of cooking styles that the whole family will love.

The Signature collection, apart from its usefulness for home use, can also be used by professional chefs.

Nonetheless, both collections offer exceptional features and will ensure your meals are healthy, nutritious, and evenly cooked.

Tip: You may also disassemble the jar’s components and hand-wash each one.
