Frequently Asked Questions
What is colourant?
Colourants are normally understood to include both pigments and dyestuff
What are pigments?
Pigments are organic or refer mainly to inorganic salts and oxides, such as iron and chromium oxides, which are usually dispersed in crystal or powder form in an application medium. The colour properties of the dispersion depend on the particle size and form of the pigment. Pigment colourants tend to be highly durable, heat stable, solvent resistant, lightfast, and migration fast.
What are dyes?
Dyes are coloured substances that chemically bond with the subtract being applied. Mainly its organic substances provide colour to the substances to which it is applied. Dyes are very soluble and can attach themselves to the fabric or substance into which they are poured.
What is organic pigment?
Pigments that contain carbon molecules. Natural organic pigments are derived from vegetable or animal extracts. They are less stable than inorganic pigments, they are commonly bonded to a mineral (inorganic) base for stability. Examples : Plant based pigment
What is inorganic pigment?
Pigments derived from inorganic compounds and salts such as metallic oxides, ochres, and earths.
What is natural earth pigment?
These start as minerals mined from the ground; they are then cleaned, dried, and the raw material that remains is ground into a powder. Their vibrant colours are caused by iron oxides and hydroxides, copper, chromium, or aluminium, as well as varying amounts of clay, chalk, and silica. Natural earth pigments include ochres, earths, umbers, siennas, and natural oxides.
What is synthetic pigment?
Synthetic pigments are dyeing compounds that have been manufactured or processed using chemical or physical processes such as oxidation, reduction, and phase transformation. These chemical processes may change the colour of the original raw material, producing different colours.
What is binder?
Binders, also known as "vehicle" or "medium," are substances that hold paint pigment in place after it dries.
How many types of binder can be used for the pigment?
Binders are classified into two types: natural and synthetic. Natural binder : gum arabic, walnut oil, egg yolk, egg whites, casein, methyl cellulose, wax medium,etc. Synthetic binder : epoxy, polyester and vinylester resins, acrylic resins, polyurethane resins, alkyd resins
How do we contribute to sustainability?
We source our material from industrial wastes that is still valuable but not usable to be reused in the source industry. Our source minerals come from various industries such as mining, manufacturing, or other sources from landfill and demolition sites.
Can mineral pigments be applied to ceramics?
Our mineral pigment could be applied to ceramics for ceramics glaze, and is acceptable to be used for decoration ceramics products.
