This set is made from hard-anodized aluminum (which gives it the grey graphite look), with a non stick interior. The handles are orange silicon, and can withstand oven heat up to 400 F. The lids are made of glass so you can check on what is cooking without removing the lid.
Here's what you get in this set: two skillets, one 8 inch and one 10 inch; one 3 quart covered saute pan; one 1.5 quart covered saucepan; one 3 quart covered saucepan; and finally one 6 quart covered stockpot. Essentially you get 6 pans and four lids in your set.
This set is safe for cooking on top of the stove and in ovens up to 400F. They recommend hand-washing the pans to preserve the non-stick interior (one tip is to make sure you soak the pans in soapy water for an hour before washing to making the wash-up quick and easy). Try to use wooden or silicone spoons when stirring to avoid scratching the non-stick interior.
You get a limited lifetime warranty on this set, as long as you don't put in it the dishwasher (as per manufacturers instructions).
Rachel Ray also does a 14 piece set, which is a lot pricier considering you only get four extra pieces (two extra covered saucepans). But I've included the price below just so you can compare and contrast! The price on the left is the 10 piece set and the one on the right is the 14 piece set.
