Larry Halvorsen constructs his pieces using a combination
of handbuilding techniques including coils, press and slump molds and
slab building. All the pieces are coated with black slip, and then using
the ancient technique of sgraffito, he carves back through the slip exposing
the natural clay beneath.
Ancient stone tools, ritual objects, shields and forms from nature are
the inspirations for sculptures and sculptural objects. He has recently
been exploring work for the wall, totems, and footed containers. The carving
on all pieces, both sculptural and functional, is the result of a life
long exploration of line and pattern.
Techniques
Stoneware: Grey to buff colored, non-translucent
clay body which matures between
cones 06 and 10.
Clay:
1) Fine-grained earth materials formed by the decomposition of igneous
rock; when combined with water, clay is plastic enough to be shaped; when
dry, it is strong; when subjected to red heat or above, it will become
progressively more dense and rock-like.
2) A compound of decomposed and altered feldspathic rock consisting of
various hydrated silicates of aluminum along with non-plastics, such as
quartz, and organic matter. It is also used as a source of alumina and
silica in glazes.
Hand-building: Assembled by hand. Finished
object may include wheel-thrown, cast, coiled and/or slab elements.
Coiling: Building the walls of pottery with
rope-like coils of clay, then smoothing the joints.
Slab building: Ceramic ware formed from flat
pieces of clay or 'slabs'.
Slip: A suspension of clay or glaze materials in water.
Sgraffito: A decorative process. A line is
scratched through a layer of slip or glaze before firing to expose the
clay underneath. From the Italian, meaning literally
"scratched out".
Fired: 1)Heating the kiln to the required temperature
for clay or glaze, at least 1300 Fahrenheit; most enamel-on copper melts
from 1300 to 1600 Fahrenheit; most clay and glaze matures between 2000
and 2300 Fahrenheit.
2) Bonfiring in a pit or on the ground
Kiln: Furnace for firing clay, slumping glass,
or melting enamels; studio kilns can achieve temperatures up to 2500 degrees
Fahrenheit depending on their construction materials; they can be fueled
carbonaceously, organically, or electronically.
Pottery: A loosely-used term meaning 'earthenware' or any
clay piece that has been fired.
