Modern Art Movement artistic works produced roughly from the 1860s to the 1970s usually associated with art in which the traditions of the past have been thrown aside in a spirit of experimentation experimented with new ways of seeing, and with fresh ideas about the nature of materials and functions of art tendency toward abstraction is characteristic of much modern art
Abstract SculptureArtists Constantin Brancusi Henry Moore Barbara Hepworth
Constantin Brâncuşi Romanian 1876 – 1957 Internationally renowned sculptor whose work blends simplicity and sophistication led the way for numerous modernist sculptors
Brancusi’s Studio and Tools
Henry Moore English 1898 – 1987 influenced by: Michelangelo, Gothic art, Pre-Columbian art, and Toltec-Mayan art felt a sense that art should return to its pre-cultural and pre-rational origins specializes in abstractions and organic shapes
Barbara Hepworth English 1903-1975 abstract form, not representational in origin worked both in wood and stone described the excitement of discovering the nature of carving as a source of inspiration in her work
Activity Using a subtractive plaster carving process, you will create a 3D abstract sculpture with open areas and texture. Research abstract sculptors, record your research in your sketchbook. Mix and mold your plaster block. Begin planning and carving your plaster.
Mixing & Carving Plaster Form, Mass, Plane & Texture
Mixing Plaster Fill container about ½ way up with warm water Sift plaster powder in slowly. Continue until there is a "little mountain" that rises in the middle. Sprinkle in a few more teaspoons around the sides. * Stir the mixture slowly with the stick without lifting it from the carton to keep as many air bubbles out as possible. Check the stick several times to see if any lumps appear at the end of it. Stop when the stick shows only a smooth, stirred mixture. Tap the container on the outside from the bottom upward many times to release air bubbles. You can see them popping. * Set containers aside to harden.
Carving Safety First: please wear safety glasses & face masks Remember the Requirements • Must be open areas you can see through • Interesting from all view points • Texture added
Using the artwork you researched as inspiration, sketch your design onto your plaster block. Be sure your design carries around the entire block. • Using a fettling knife start carving to open the piece so that you may see through it. • Round off some of the edges a little at a time… • Remember: once the shape is cut, that piece is gone forever… you can’t add it back in later, work slowly
Make shapes comeforward (by cutting away whatever is around it) or recede (by cutting it back)
While the initial work is continuing, the block is kept wrapped in very damp paper towels, and placed in a plastic bag until it is needed again.
TEXTURE ADDS DETAILS TO SCULPTURE Can become part of the entire surface of the sculpture or be especially limited to particular areas.
Tips • Keep the block wrapped in very damp paper towels and a plastic bag between classes. • Soak plaster in warm water to soften and ease carving process. • Work from general to specific when sculpting – keep the form strong by having it generalized. • Sculpt and carve the plaster EVENLY throughout the process. If you have finished a fine detail area then work on an unfinished section you run the risk of breaking fragile areas.
