Boiler House Door

Inside the Boiler House at Portland Cement Works, a metal door stands corroded to its core. Paint has lifted and curled away from the surface in large sections, leaving bare rust across almost the entire face of the door. Light enters from one direction and barely reaches the interior, picking out the grain of the corrosion and the warped edges of the frame. There is nothing decorative here. The door was a working door in a working building, and what it looks like now is what happens to mild steel after decades of neglect in a structure that is no longer maintained. The Portland Cement Works Precinct sits on Williwa Street in Portland, City of Lithgow, in the NSW Central Tablelands. The Commonwealth Portland Cement Company registered in December 1900 and began cement production in 1902, using coal-fired rotary kiln technology that placed the works at the leading edge of cement manufacturing at the time. By 1912, the company was producing approximately 40 per cent of all Portland cement manufactured in Australia. The works operated through expansion, depression, war, and mechanisation over nearly nine decades, with cement production continuing until November 1991. Limestone quarrying continued until 1998, when the last quarry was decommissioned and dismantling of the plant began. The Boiler House was part of the industrial core of the site. The works that surrounded it operated on coal the company mined itself, water drawn from its own supply, and power generated on site. That degree of self-sufficiency sustained production for close to ninety years. What the 2018 photograph records is what that infrastructure looks like after the last shift has long since ended: a rusted door in a dim room, paint gone, metal softening at the surface, the whole thing still standing because it was built to last.
