I'm an artist, and a recently retired teacher of Art and History of Art, and also of Religion; I am still a Cathechist in our Catholic parish taking care of the teenagers who are being prepared for the Sacrament of Confirmation; and I give summer courses in painting in layers (acrylic and oil). In the year 1978 I was asked to continue my own teachers courses in the "Misch technique" of Ernst Fuchs (Austrian painter who was searching for the Technique of the old Masters, and found a working technique, mixing oil painting and egg tempera in layers). I later left the "misch technique" of Fuchs (after learning about criticism in Journal of Conservation) but have continued painting in layers using acrylic colour finishing the pictures in oilpaint. The use of other colours than white as a ground has been with me through the ages wether as "Imprimatura" in the Fuchsian technique, using a ochre priming as Leonardo or Brueghel for example, or different coloured papers when working in dry pastels, and sometimes using the natural colour of masonite work as part of a priming. Working with white as light (as in an underpainting) is something that's been a contant line through my artistic life, until recently when I've delved into the pop/op world of patterns in doing serigraphy art. The volumes created by distortion of simple patterns has been my new fancy - just like the volumes created by the mimicking of light has been from early on in my artistic work. But I still love working with the light!
