Cast Iron and Its Origins
March 16, 2023

Ornamental ironwork was primarily presented through wrought iron until the latter half of the 18th century and the industrial revolution. In Britain the cast iron material was originally popularized by the Adams Brothers who first recognized the value of cast iron and its usage for mass production in standalone structures.

It increased in popularity in Victorian times and was mainly used for making gates, railings, panels and the decorative elements they incorporated. Historic cast ironwork is special in that it requires appropriate treatment. It is a sensitive aspect of heritage as it is difficult to repair and should be handled by a professional who is guided by principles of reputable heritage conservation organizations.

Conservators should always try to maintain as much of the original material of the element by using traditional and informed techniques. Historic cast ironwork fittings can be permanently damaged by uninformed handling and treatment as it is a brittle material, tends to break under stress and can be easily damaged by modern techniques and tools. The replication of historic cast ironwork requires the traditional skills of a blacksmith as the spoiling of the original metal represents a permanent loss of historic fabric.

Through colonization, cast iron became a common material in the architectural features of religious, commercial and residential buildings across the Caribbean. Many historic buildings in Trinidad and Tobago still possess identifiable cast iron elements that have withstood the test of time. Many of the buildings built in the beginning to the middle of the 18th century which used Cast Iron, tend to have Cast Iron fences or gates to border the property. This can be seen on Queen’s Royal College, Mille Fleurs, George Brown’s House, Sacred Heart RC Church and much more. Beyond being popularly used for railings in Trinidad and Tobago, cast iron is also a very involved component in the interior and exterior features of buildings from decorative elements to supporting structures.
