Porth Wen Brickworks

Remains of winding house

The brickworks were supplied from two quarries to the north-west of the works.[8][9] A tramroad from one of the quarries leading to a winding house and incline was shown on the 1st edition OS map, 1889.[10]

The winding house includes two lateral walls of mortared walls of rubble masonry supporting a square drive shaft and bearings. The remains of the walls are splayed at the bases and roughly 4.5 m (10 feet) in length, 0.95 m (3 feet) wide up to a height of 3 m (10 feet).[10][11] The drive shaft supported three wheels each with eight spokes. One wheel is roughly 2 m (7 feet) in diameter and the other two are 1.5 m (5 feet) in diameter. The larger wheel was a banding-break and the other two were driving wheels for lowering and raising trucks on the incline. A wooden beam with a control mechanism remains in front the drive shaft. A second similar wooden beam lies nearby but is no longer in position.[10][11][12]

Near the winding house are the remains of a storage shed roughly 4 m (10 feet) by 5 m (20 feet) with walls that supported a gabled roof of profiled sheeting and is probably more recent than the winding house, built in a period of improvement in the early 20th century.[13]

The incline consisted of two tracks which have been removed but the track bed remains with retaining walls of random rubble masonry roughly 1 m (3 feet) deep. The incline was gravity powered.[12][14]

Crushing house

The incline terminated at a crushing house where pieces of quartzite were broken up with a knapping machine. The pieces were passed down chutes to lower levels for further processing, resulting in a fine powder at the lowest stage. It is likely that the pieces of quartzite were reduced by hammer with the workers wearing iron covered gloves.[1][15][16]

The resulting powder was mixed with lime and water in a pan mill. The resulting paste was then moulded and pressed into bricks in the moulding shed, and then dried out in drying sheds.[1][17][18][19] Originally bricks were made using moulding and wire cutting, but were later made using a press.[16]

After drying, the bricks were then fired in one of the three circular down-draught kilns (also known as beehive or Newcastle kilns), made of brick with iron bands and domed roofs.[20][21][22][1][7]

The brickworks also includes the remains of a boiler house, which contained a Five-drum Stirling boiler, and a small engine house for a steam engine.[23][24]

After firing, the bricks were stored in the main building, an impressive two-storey brick building, with gabled ends.[25]

Bricks were then loaded onto ships, using a crane, moored at the loading quay.[26][27]
