Giacomo Balla
Technical analysis of the painting

Balla painted his picture using white and black distemper direct on the unprimed canvas. He applied the black, which consists of carbon black, vermilion, chrome yellow and zinc white, in very diluted form, leaving the canvas visible in a number of places. In most cases, the white and the grey tones were applied more thickly, achieving better coverage.
The work is signed in white paint in the lower left corner: 1913 BALLA.

We would like to thank the Swiss Institute for Art Research (SIK-ISEA) for analysing the painting materials.
