Although this place has been gutted when it was vacated there's no real sign of vandalism even after 7 years, just natural dereliction. After spending a few hours here over the last week or so I found it to have a real organic charm. I'm sure this place has been done before, though I couldn't find it with a site search on here so here's a bit of history just in case...
The site was originally the Gem Brick Tile and Terra Cotta Works Company and locals still refer to the site as the 'Gem'. In 1901 it was voluntary wound up and the Alyn Brick Tile & Terracota Company took over. The chimney was added in 1911 (built by Ephram Jones). By 1916 the plant had closed and it was then refitted as a silica works by Colin Steward Ltd. Local hard silica sandstone was taken from a quarry above the site and transported in trams down a cable tramway (there's still the remains of the winding houses up in nearby fields) The stone was then ground down to powder that was used by Lever Bros as the scouring agent in 'Vim'. The plant produced 600 tons of powder per week which was transported by rail from a private siding. The silica dust by-product was diverted to the chimney where it was captured by a water spray and piped to a nearby pond where it solidified and reclaimed the pond and marsh back into land. Colin Stewart Ltd closed when Levers ended the contract in 1959, More recently, the site was acquired by Clwyd Alloys, and was used as a foundry for the reclaimation of scrap metal. The site closed in 2002, and outline plans for housing have been submitted.
There's numerous structures dating from all periods with up to three floors in places. There's what looks like a couple of vibrating tables, hoppers and other left over bits and pieces that were probably too bespoke to be used elsewhere. Water for the plant was taken from the Nant that flows underneath the site and there's a handful of access points for this. There's also an old Pooley weighbridge, dated 1948 that's in great condition.
