    It is a subtractive process; it

    involves removingunwanted portions of theraw material to reveal theform that the artist hasvisualized. Wood, stone

    and ivory are the materialsemployed in this process.

    MODELING

    It is an additive process. It means

  • 8/11/2019 5aelements of Arts Saste Final

    123/170

    building the form, using highly

    plastic material such as clay orwax. This results in a type of

    creative spontaneity. Theadditive process permits theartist to rework his materialand introduce details as he

    sees fit.

    CASTING

    It is a complex process. It uses

  • 8/11/2019 5aelements of Arts Saste Final

    127/170

    bronze and other metal for it

    to materialize. It begins withthe production of a negative

    mold. Then the artist coversthe original model with amold in such a way that a

    faithful negative reproductionis created.

    ARCHITECTURE

    The extent to which a building

  • 8/11/2019 5aelements of Arts Saste Final

    135/170

    may be considered architecture

    depends upon the degree towhich the four basic elements

    of FUNCTION,CONSTRUCTION, DESIGNand SPACE have individuallyand collectively contributed to

    its form.

    But great architecture isproduced only when:

    produced only when:

    1. The elements offunction and

    construction areintegrated by creative

    design.

    2. The building hasacquired a significance

    that transcends itsobjective character.

    In terms of design, the fundamentalbl i t d fi th l f

  • 8/11/2019 5aelements of Arts Saste Final

    141/170

    problem is to define the volume of

    space in the structure by the formsthat will enclose it. Through designa positive relationship between thesolids and the space is established.The character of a building will be

    ultimately determined by thetreatment of space.

    two vertical members that support ahorizontal one. It is the simplest of thethree basic structural principles for the

    vertical members need only besufficiently strong to support thehorizontal weight. Even if some

    additional weight is placed on thelintel, the stability of the system is notthreatened, if its span is not too great.

    being the simplest of the three

    ARCH

    In its simplest form, the archconsists of a semicircle of wedge

    consists of a semicircle of wedge-

    shaped blocks called voussoirs,the topmost one being the

    keystone.The bottom face of thelowest voussoir on each side is

    called an impost.The top face of

    the upper most stone of whatevermember supports it is called the

    springing.

    Arch ofSeverus, Rome

    159/170

    The arch has some inherent shortcomings.It must be supported on a scaffold, while

  • 8/11/2019 5aelements of Arts Saste Final

    160/170

    pp ,it is being built. Such a scaffold is calledcentering. It is usually of the form and

    size of the opening to be spanned by thecomplete arch. The voussoirs are laid

    upon it, and then locked in place byputting in the keystone. The keystone,

    subjected to the law of gravitation, has a

    constant tendency to fall. However, this isavoided when proper compensation of the

    whole structure is made (buttressing).

    beyond its supporting post. Its freeexternal end is unsupported, and thepoint where it rests on its post, acts like

    the fulcrum of a lever. If the internal endof the beam were not bolted down orcounterweighted in some fashion, the

    cantilever would rotate around itsfulcrum. Since the inside end is fixed,

    the free end is rigid.
