| Manufacture | The manufacture
of pigments is normally mechanical. The earth pigments are cleaned and
dried, the most important aspects being the purity of the earth and the
fineness of the milling process. The Ultramarine pigments are clays which
are burnt with sulphur at high temperatures. Spinel and Rutile pigments
are chrystaline structures, containing metal, which produce the different
colours. Red pigments, such as Oriental Red and Salmon Red, are enhanced
with food colourants. Mica pigments are silicates. Rhine Gold is milled
bronze. All pigments are free of poisonous heavy metals. |
| Preparation | A small amount of
the medium to be coloured must be added to the pigments to make a paste. For example: For Silicate Paint – soak pigment in a small amount of Silicate Primer and use straight away. For Hard Oil – soak pigment in a small amount of Hard Oil . For Casein or Emulsion - soak pigment in enough water to cover the powder, preferably overnight, to create a liquid paste. For immediate use, soak pigments in alcohol or methylated spirits. When mixing pigments into any medium, always make a note of the amounts used. Avoid contact with clothing as pigment may permanently stain fabrics. |
| Application | Add the prepared
paste to the medium. Always leave a small amount of the coloured medium
to add to the next mix. |
| Note | If you are sensitive
to dust it is advisable to wear a mask when mixing pigments due to their
particle size, especially Rhine Gold, Oriental Red and Salmon Red. Rhine Gold pigment may oxidise depending on use. The Mangan purple pigment should be mixed in just before use. A cloudy appearance can be caused by a high concentration of very colour intensive pigments eg., Ultramarine Blue and Red Oxide. |
| Colour Charts | Colour charts are
available using the pigments in Casein Paint and Emulsion.
|
| Special Effects | The pigments
can be used with Clear Colourwash and Casein Paint to create
a variety of colourwashes. Pigments can also be used to colour Textured
Wall Finish. |
| Cleaning | Wash tools in warm
water and soap. Wash hands using Hand Cleaner, if required.
|
| Storage | Keep bag sealed
and store in a cool, dry and frost-free place. Shelf life is unlimited in powder form for unopened containers. |
