To prepare Pigments and poster paints using various chemicals and reagents 
1.Pigments-A pigment is a finely divided material which contributes to optical and other properties of paints. Pigments may be classified according to their composition or source which they are obtained from. However the most common and useful classification is that color pigments can be made using simple chemical reactions and techniques.
2.Poster Paints- Grinding a pigment or a mixture to a very fine powdered and then suspending the powder ina very fine liquid makes poster paint so as to a uniform suspension. For making poster paints the pigents made by various chemical reactions are thoroughly mixed with the medium. Sometimes the paint hardens but the addition of lukewarm water to it can soften it.
3.Medium- Medium used for making paints is made by mixing 30ml of clear glue with 10ml of water and adding a drop of liquid detergent to it.

Requirements -

Chrome Yellow Chemically known as LEAD CHROMATE (PbCrO4) the yellow pigment is obtained as follows:
1. Dissolve 7gm of Potassium Chromate in 50mL water and 10gm Lead Nitrate in 100mL water in Two Separate Beakers.
2. Pour The Potassium Chromate Solution...
