In my opinion i would say plastic,stainless steel and wood
Obviously, not all saucepans have plastic handles, but most saucepans have insulating handles - wood is another common material - so that they can be safely picked up when the rest of the saucepan is hot.
Because the plastic handle act as a thermal insulator, to avoid burns on your skin.
Whether a saucepan can be used in an oven usually depends on the type of material from which the pan's handles are made. If the pan has a wooden or plastic handle, it should not be used in an oven. Most commercially manufactured saucepans have heat resistant handles, and may be used safely at baking temperatures up to 375 degrees Fahrenheit. If there is any doubt as to the material of the handles, do not use the pan with higher temperatures - broiling, for instance, might not be safe.
Typically, saucepans are made with a heat-resistant plastic handle, because metal handles conduct heat, making it easier to get burned if the cook isn't careful.
Aluminium.
The only metal used in making various Strider Knives is Steel. The handle material of Strider Knives are made of Paracord or G-10 Fiberglass for handle material.
MSDS software, or material safety data sheet, is used to provide workers with a list of safety guidelines so that the handle material is used correctly.
good cooking ware use the material used in public phones for handles.
normal wood
Because metals tend to be very effective at conducting heat. As such a metal handle will tend to get very hot as the pan gets hot. Obviously this increases the risk to the user, so saucepans commonly have handles made of a material that is a poor conductor of heat.
The Romans used the hearth to cook. They also had saucepans.
Thermosetting plastics such as polyoxybenzylmethylenglycolanhydride better know as 'Bakelite' and some others.
