This exhibition pays homage to Didcot’s 50-year-old coal-fired power station. As plans are in place to demolish it, the show serves to recognise the impact it has had on the landscape, as a pollutant and as the provider of electricity on which we all depend.

The exhibition is by a group of nine artists who have worked and studied together. They call themselves Alchemie as an acknowledgement of the chemistry that exists between them.

Ken Williamson combines an acknowledgement of the pollution caused via his extensive use of black to frame his images alongside a lighter celebration of the scale of the enterprise. In Caterpillar the mechanical concerned is filling itself with coal from a million-tonne mound against a sky flushed with dramatic expanses of golds and reds, themselves a by-product of a glorious sunset made by the presence of polluting particles catching and refracting the sun’s rays.

Julie Wigg uses alternate layers of thin oil glazes and thicker acrylics to respond to the natural movement of the heat and steam from the towers and their inter-play with the surrounding landscape. She has created a series of small pictures with a huge impact. In Fire Breathing Dragon she uses vibrant hues of reds to create a piece that throbs with energy, in contrast with her Looming Rock of Coal where the dark power of the coal dominates all other colours in the piece.

Sue Cox has created three intimate portraits of the towers. Her delicate use of charcoal on paper emphasises their simplicity and imbues them with a sense of vulnerability, which is indeed the case with their future under threat.

The exhibition is at The Cornerstone, Didcot, and it is open daily and continues until November 27.
