Definition

Noun: - A type of cement: A substance resembling putty in consistency, specifically formulated by mixing ferric oxide (iron oxide) with boiled linseed oil. Its key property is resistance to acid corrosion.

Usage

• Primary Use: This compound is used as a specialized cement or sealant in applications where resistance to acidic substances is required.
  • The chemist used iron putty to seal the joints of the acid-resistant drainage system.
  • Before the advent of modern plastics, iron putty was a common material for lining chemical containers.

Advanced Usage

• Technical/Industrial Context: The term is primarily used in technical, industrial, or historical descriptions of materials and processes, particularly in chemistry, plumbing, or vintage restoration.
  • The restoration of the 19th-century laboratory required a period-appropriate sealant, so they recreated the traditional iron putty formula.

Variants and Related Words

• Iron oxide cement: A more general descriptive term for cements using iron oxide as a component.
• Linseed oil putty: A common variety of putty made with linseed oil, but without the specific acid-resistant properties of iron putty when combined with ferric oxide.

Synonyms

• Acid-resistant cement
• Ferric oxide cement

Notes on Meaning

• This is a highly specific technical term for a material with a defined composition (ferric oxide + boiled linseed oil) and a key functional property (acid resistance). It is not a general-purpose material like standard putty.

Noun

1. a cement resembling putty; made by mixing ferric oxide and boiled linseed oil; is acid resistant
