putty, cementing material made of whiting (finely powdered calcium carbonate) and boiled linseed oil. It is beaten or kneaded to the consistency of dough and is used to secure sheets of glass in sashes, to stop crevices in woodwork, and to fill nail holes. Whiting putty of a high grade consists of 85 to 90 percent whiting blended with 10 to 15 percent boiled linseed oil. White-lead whiting putty has an admixture of 10 percent white lead, reducing the amount of whiting proportionately. Prepared putty should roll freely in the hands without exuding oil. Synthetic glazing and filling compounds have supplanted putty in many applications.
The name putty is also applied to substances resembling putty, such as iron putty, a mixture of ferric oxide and linseed oil; and red-lead putty, a mixture of red and white lead and linseed oil. Certain doughlike plastics are also called putty. Putty powder (tin oxide) is used in polishing glass, granite, and metal.
