[6] The 69 ft (21m) sculpture is made from COR-TEN Steel, the same material as the Angel of the North and was fabricated in Nottingham.

[7] The tapered lozenge design, shaped to evoke a solitary flame such as lit the Chatterley Valley during the heyday of the Iron Works, features powerful colour changing LED lights that illuminate 1,500 hand blown glass prisms containing wishes or memories of local residents written on handmade paper.

[8] Each prism is held out from the main body of the sculpture by a short stalk, giving the artwork a bristly appearance.

Local arts group Letting In The Light was commissioned by artist Wolfgang Buttress to collect the wishes and memories.

Although people cannot see the messages while the sculpture is installed, the Letting in the Light previously planned to publish them in an accompanying book.
