Many walls and ceilings were covered with oilcloth fabrics and combustible soundproof tiles. Eventually it was purchased by Williamson, who moved linoleum and oilcloth manufacture to Lancaster. Dull-colored oilcloth was used for bedrolls, sou'westers, and tents. His family's business in Lancaster produced oilcloth and linoleum, which was exported around the world. For better protection against rain, dusters were made from oilcloth and later from waxed cotton. Less common materials can include polyester, hemp, metal, or "oilcloth" (vinyl woven with cotton). Seams in traditional oilcloth could be coated after sewing to reduce leakage through their stitching. The tables were covered with red-checked oilcloth that could be wiped clean rather than laundered. Historically, pre-Mackintosh, oilcloth was one of very few flexible, waterproof materials that were widely available. The playroom is a huge space with walls in red oilcloth above and aluminium below. This would be tarred or treated as oilcloth for weatherproofing. Overlaps between sheets of fresh oilcloth would amalgamate naturally when pressed together. Re-enactors may boil their own oil in the search for a correctly coloured oilcloth. In 1830, Ezekiel Bailey began the commercial manufacture of oilcloth. One of his specialties was painting directly into black oilcloth.
