Coal Tree Salt Sea
Coal Tree Salt Sea is an inter-disciplinary body of work which began as an Arts Council Wales funded research and development residency in partnership with the Josef Herman Art Foundation Cymru in Ystradgynlais, near Swansea in 2015 (originally called Coal Tree). This started as a response to the area around Ystradgynlais, the place that Josef Herman called home for eleven years. Herman was mainly a figurative artist, yet he sought out the wild desolate places to walk and as Sarah found, Ystradgynlais is in an extraordinary, dramatic and culturally rich landscape. She walked alone and with people that know the place intimately, she also befriended an amateur archaeologist who had exhumed an amazing collection of items from the area. Some of these were shown in the exhibition, displayed alongside artworks.
Ystradgynlais was part of a very significant coal mining area, rich in seams of anthracite, central to people’s lives. The main piece of work that Sarah made was an installation in the landscape. A hollow oak tree filled with three quaters of a ton of anthracite, sited on a hill in Cwmgiedd nearby. The tree is ‘birthing coal’.
Sarah arranged a local May time event around the tree with Welsh folk music, poetry and a picnic.
There are ritual uses of coal as well as salt, both are symbolic materials which were carried to a new home when moving. Salt has a mining culture that has parallels with that of coal. This took Sarah to Poland to explore the salt mines of Wieliczka.
Salt (once known as ‘white gold’) is the Albdeo, one of the triad components of alchemy and has deeply symbolic connotations with purification and substantiation. It has been used in ritual processes over the millenia and coal (black gold) , born of putrification from drowned forests can be seen as an aspect of the Nigredo, it expresses deep geological time and metamorphosis.

Exploring symbolic meanings in both Coal and Salt
“ Alchemical salt, like any other alchemical substance, is a metaphoric or ‘philosophical salt’.
Coal has alchemical characteristics; born of putrified matter; it can metamorphically transform again to the next stage which is diamond.
