Answer:
A pot-holder is a piece of textile (often quilted) or silicone used to cover the hand when holding hot kitchen cooking equipment, like pots and pans. They are frequently made of polyester and/or cotton. Crocheted pot-holders can be made out of cotton yarn as a craft project/folk art.
A pot-holder offers protection for only one hand at a time. To lift a pan with two hot handles using both hands, two pot-holders are needed. For holding a hot piece of equipment, the pot-holder is folded around it and grasped with the hand. Generally a rubber surface will be on one side to grip and a fabric side to absorb the heat on the other side.
