    My goals

    By the end of this Unit, I will be able to:

    ⦿ Describe the process of preparing clay.

    ⦿ Make a sculpture in clay.

    ⦿ Decorate the surface of a clay piece.

    ⦿ Make a mask and decorate it.

    ⦿ Share ideas with others about modelling.

    Introduction

    Modelling is a very old activity which has been done by

    different cultures. It includes both pottery and sculpture.

    There are many figures which have been formed using clay.

    For example look at the ceramic wares from Gatagara Pottery

    in Figure 4.1.

    l

    Activity 1

    1. Look at Figure 4.1 and mention the different objects in

    the picture.

    2. Identify the patterns used to decorate these objects.

    3. Which materials were used to make these products?

    In Senior One you studied about modelling where you learnt

    about clay and its uses. You also studied about the different

    methods of making ceramics (such as pots, cups and bowls);

    these include pinch, coil and slabs. You studied about the

    different methods of decorating ceramic articles. You learnt

    that clay was used as the basic material for ceramics. Clay

    can further be used in other ways.

    In this unit, we are going to learn more about modelling in clay

    by exploring additive and subtractive methods. For example,

    look at the two sculptures in Figure 4.2.

    l

    Figure 4.2: A male and female sculpture made out of clay

    Activity 2

    1. Observe the sculpture in Figure 4.2 and identify the

    activites represented.

    2. Discuss the sculptures in terms of form and use of clay.

    3. Look at the surface of these sculptures and discuss how

    their texture was made.

    Clay preparation

    In Senior One you learnt about clay preparation. You studied

    about four different methods of clay preparation namely;

    The plastic method: The method is often used in brick

    making. The available moisture in clay

    is used to prepare it.

    The wet method: Where clay is dissolved in water to

    form shap. Then it is wedged to loose

    moisture and prepare it for use. It is

    good for making pottery.

    The dry method: Clay is dried, pounded and crushed

    into powder form. It is often used in

    factories for making tiles.

    The semi dry method: Combines both dry and plastics

    methods.

    Each method has got advantages depending on where it

    is being used. However, it is always important to get rid of

    unwanted materials such as stones, plant roots from clay

    during its preparation. Grog is always added in clay for

    sculpture in order to make it stronger and to ease the firing

    process.

    Remember, clay has to be kneaded and pressed during its

    preparation in order to get rid of air pockets. This is also done

    in order for the clay to become more plastic.

    Activity 3

    1. Discuss the four different methods of clay preparation.

    2. Which method is more suitable for preparing clay for

    pottery?

    3. Which method is more suitable for the preparation of

    clay for sculpture?

    4. Follow an appropriate method and prepare your clay.

    Keep it in a safe place.

    Take note:

    · The quality of clay determines the quality of the object

    formed. When clay is well prepared, it can be used to form

    fine objects.

    · Objects can easily break if they are made from poorly prepared

    clay.

    · Ready clay should not crack when pressed, it should be even

    such as the one in Figure 4.3.

    l

    Moulding different clay figures

    Your hand is the basic tool while moulding clay. This applies

    to both additive and subtractive methods of forming art works.

    Clay figures can be made by use of the following methods:

    · Using coils

    · Using slabs

    · Additive method

    · Subtractive method

    Activity 4

    Discuss the four methods above and write how each one of

    them can be applied for making clay work.

    make clay figures such as masks. As you may have observed,

    these methods are commonly used to make pottery and

    ceramic sculpture. You can make a sculpture using the additive

    method, by putting together small pieces of clay until you get

    the whole sculpture desired. For example, the sculptures in

    Figure 4.2 were made using the additive method.

    Substractive method is where you begin with a big piece of

    material which you keep reducing until the required sculpture

    is got. Subtractive method commonly applies to such materials

    as wood and stone. However, it could be used in clay. For such

    a method, you pile up a lump of clay, then you keep removing

    pieces until you get the required form.

    How to make a mask from a mold

    Remember, a mask is an object which is normally put on the

    face to disguise one’s identity. Since it is to be worn on the

    face, a mask is usually made of light materials such as wood,

    plastic and paper. For example, look at the masks in Figure

    4.4.

    ;

    Figure 4.4: Local masks

    You can make a mask of your own using a mold. A mold is a

    form which is used to give shape to another softer material. In

    this unit we shall use clay to make a mold.

    In order to make a mask using a mold, you begin by thinking

    about the purpose of your mask. From the purpose you can

    develop a title for your mask. For example, your mask could

    be used to entertain people on a festive occasion. You need

    the following materials in place.

    · Clay

    · Waste papers

    · Glue

    · Polythene material

    · Vaseline

    · Colours

    · Brushes

    · Small stones or seeds

    · Raffia and threads

    Then you follow the steps below:

    lStep 1

    Develop sketches for

    your mask as shown

    in Figure 4.5. Making

    a sketch helps you

    to develop and put

    ideas together and it

    acts as a guide while

    forming your work.

    Figure 4.5: Sketches for a mask showing the front and side view

    Step 2

    kUse clay to make your mask

    mold. Look at Figure 4.6.

    Avoid creating pockets on

    your mold. These are areas

    with depressions within

    the mold. Such pockets

    make it difficult to remove

    the mask off your mold.

    Figure 4.6: Forming a mold for the mask out of clay

    Step 4

    lUse a tool to create a smooth

    finishing on your mold as

    shown in Figure 4.7. This

    could be a table knife or a

    smooth stick. This would

    further help you to remove

    your mask so easily. Never

    allow your mold to get

    dry. Always cover it with a

    polythene material whenever

    you break off.

    Step 4

    lWhen you are done

    with the mold, smear

    its surface with

    Vaseline. (Figure

    4.8). This eases the

    removal of the mask

    after completion

    Figure 4.8: Smearing the clay mold with vaseline

    Step 5

    oTear small pieces of paper

    and carefully use glue to

    fit them on your mold

    as shown in Figure 4.9.

    When you are done with

    the first layer, apply glue

    and add another layer.

    Whenever you add three

    to four layers expose your

    work to get dry.

    Figure 4.9: Applying papers on the clay mold

    Step 6

    lWhen you are done and

    satisfied with the thickness

    of the mask, carefully get

    it off the mold. This can be

    done by scooping clay out

    and you remain with the

    image in papers. Then turn it

    around and work on its inner

    parts. Look at Figure 4.10.

    The inner part of your mask

    should be as smooth as the

    outer part

    Figure 4.10: Finishing the inner part of the mask after

    Step 7

    lThen cut out the

    provision for the eyes

    as shown in Figure

    4.11. Prepare colours

    and paint your mask

    according to your plan

    or sketch. Add a string

    for holding your mask in

    place.

    Figure 4.11: Cutting out the provision for the eyes

    Step 8

    kYour mask could be

    decorated further by

    adding more colours,

    raffia and a rough texture

    with small stones or

    seeds. For example look

    at Figure 4.12.

    Activity 4

    1. Follow the steps above and make your mask to be

    used on an occasion. Decorate it using the available

    materials.

    2. Display your work and discuss it with classmates

    Decorating clay surfaces

    Clay naturally has its texture. But this can be changed by use

    of different tools to improve the appearance of the art work.

    Consider the following techniques of decorating clay

    surfaces:

    · Smoothening: the article is made smooth with a tool, then it

    is fired.

    · Glazing: glaze is applied to the surface of the article at bisque

    level, the article is then fired for the second time. Glazing can

    be done in one uniform colour or with patterns.

    · Painting: a technique where colours are applied to an article

    after firing. Such colours are applied following particular

    patterns.

    · Incision: this is done by using a tool to cut patterns into the

    surface of an article.

    · Building: the surface of an article is decorated by adding small

    pieces on the surface while following a particular pattern.

    Activity 5

    Observe the clay pieces in Figure 4.13 and 4.14, and

    mention the technique which was used to decorate its

    surface. (Choose from these; building, incision, painting,

    glazing and smoothening).
