Mission Gold Watercolour paints are the first ever to be manufactured without thickening agents.
Silicon dioxide, a thickening agent used in the manufacturing of watercolour paints, has an adverse effect on the clarity of colours in that it is incapable of dissolving in water. This property prohibits the even spread of paint as pigments cling to these solids and will appear granular on paper. This effect, known as Phenol Phenomenon, causes the solidification and caking of pigments which decreases colour vibrancy and transparency. In creating this watercolour the researchers at Mijello developed a process to make paints naturally viscous and free of any thickening agent. The result is chromatically pure and intense colour, even when mixed with other Mission colours.
For example, the visible differences between smooth and rough skin are easily distinguished with a microscope. A person’s complexion appears unclear and uneven when the skin contains excess keratin. After exfoliating, skin tone becomes more even and complexion becomes clearer. In the similar manner, paint colours can appear muddy when they contain any lumpy granules of pigments. Hence, watercolour paint without a thickening agent can achieve excellent transparency, vividness and smooth flow.
