that are made of clay or thin metal ,that we can later exclude the clay out
from the negative.
B. on the sculpture we pour the cast , the density that
enables building the negative
layer 1 - very diluted , and after that we
mix the cast , antil it gets ruffer and than we
can work with it more acuertly .
it is recommended to use an alabaster cast .
C. wait antil the cast is hardent ,and only than it should be opend.
minimal waiting time is at least half an our .
put your hand on the cast and feel the heat that rises from the negative .
when the cast is hot , it means that the negative is getting hardent .
D. open the negative ,get the clay out , mesure its qauntity, this will be
the quantity that you will need .
E. take care of the negative , wash it , clean it , rasp it , immerse in water
the parts of the negative , and only after that close it.
tie it with metal strings and peices of cloth around the negative.
F. turn the work up side down , create a metal structure inside the
negative ,wich will be used as the main colom of the work.
G. prepare a diluted mixture densited like sower cream and cast it
inside the negative .
mixture should be third 'white cement' and tew
thirds of other matirials 'sand,marble,graind stone'.
H. shake the negative , to releace the the trapt air inside the negative .
I . leave the work for at least 4 days in them you will water it every day .
put a wet rag on top of the work.
J. release the work from the negative , put over it
a wet towel ,to let dry graduatly.
K. rasp the work :
1. a dry rasp with paper and machine .
2. wet rasp with rasping papers.
3. a rasp with dymonde cups .
the finish work should be smuth as marble .
due to its metlic proportys bronze casting enables
to create thin and hollow objects with movemnet sometimes
that stand on a tiny and delicate spot.
to the method of casting we call in the profetional language
" the method of the lost wax " .
A. the sculpture is made out of clay, cast, wood, or stone .
B. we create for it a robber mold .
C. we pour inside the robber hot wax and create the
figure of the sculpture of a thin layer of wax .
D. we take of the wax , fix it , smooth it .
the final care of the wax determens the condition
of the bronze, smooth or textured.
E. the sculpture from the wax gets in to a cermic oven
,and a cermic layer covers it.
F. the ceramic goes thrue a ceramic prosses.
the ceramic gets into a hot oven in a inverted way,
and the wax gets melted .
that's why we call it the "lost wax prosses".
G. inside the empty space that was created we pour the hot metal.
H. when the metal gets cool (it take one hour)
we brake the ceramic that seronds it and
clean it by sandblasting it .
I. we start to scrape the bronze , the prosses of the scrap
and level of the scraping determens the qaulity of the work .
the prosses take up to a month of work'
for an average creation .
a big work must be divided into sevral pieces and after
they are finished we weld them togather.
what is bronze ?
a segment of copper and tin and small amounts of other metals.
propertys
1. it is able to be procesed up to maximum accuracy.
2. it gives the creation a perfect finish .
3. it is srong and can stand a differnt kinds of weather .
4. has multipule colors in green and brown.
5. can be coverd with gold and silver.
other metals that can be used for casting sculptures in the same method:
lead
copper
brass
the drawing of sculpture enable us to scan the creation
prosses when it is happening, the sculptors usualy dont
draw whole scenes, but clear description lines , as a way
to show and explain them .
sculptures are drawed for several reasons :
A. the will to acquire information , to edit researches in
the positions and structure of the human body.
the sculptor "ogust rodin " drew houndred of scaches
of the human body in a moment of relief or motion
with tiny lines in order to mesure the volume of the body.
B. the will to conserve ideas and to look for ideas in order
to design a special sculpture .
C. "Demonstration Drawings" with them the artist shows
to the client who ordered a sculpture how the sculpture will be .
these drawings usualy are made with complete details and
not only ,with segmented description lines.
metamorphy dolomite stone that can be smoothed in
order to make them shiny .
that their strength will enable to built with them
and also to carve them .
the marble has many colors begining with gray
,red ,redish,yellow,pink,and green.
Famos Quarrys in the World
1. the greeks carved the aptentanon temples from
the quarrys pentelicon in atica , north east of athene.
2. famos quarrys were also in the paros island , one of
the ciklete islands in the egean sea.
the rome also carved there in the helenistic period of time.
3. in the renesans ,the italian carved in the town of carera in
the region toscany .
people are still mining marble from there also today.
the marble that comes from carera is exceedingly
white pure clear and was used as a major substence
in michael angelo works .
due to it proprtys it is easier to scalp more then a vulcanic rock.
the vulcanic rock, the granite and the basalt are hard
to sculpture with.
lime stones are the main substence for sculpturing
arround europe.
