Thomas Arnolds works in self-contained series on a range of subjects, examining and analysing painting processes and putting the technique itself at the forefront of the work. The current works in the series MARB7 (2015/2016) relate to structures made of marble, from which the name of the series is also derived. As a stonemason and stone sculptor, Thomas Arnolds is familiar with this material in its natural form. In his two-dimensional engagement with the stone, the picture is created (as in the case of sculpture) by subtraction of the material: the painting process arises not by the addition of colour to the canvas, but by scraping with various tools into two superimposed layers of colour in yellow and black.
