A potholder 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 potholders can be made out of cotton yarn as a craft project/folk art.
A potholder offers protection for only one hand at a time. To lift a pan with two hot handles using both hands, two potholders are needed. For holding a hot piece of equipment, the potholder 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.
When made of textile fabric, potholders typically have an inner layer of a material providing thermal insulation sandwiched between more colorful or decorative outsides. The most common type commercially available nowadays has the form of a square, with a side length varying from 5 inches (13 cm) to 10 inches (25 cm) and slightly rounded corners, and a textile loop at one of the corners for hanging.
