Sennelier inks, which are likened to Indian inks, are available in a selection of high quality colours. Extremely rich, these inks are manufactured with shellac gum giving (to each shade) unique brilliance, brightness and vibration under light. They can be applied with a brush or ink pen and give a satin to brilliant film depending on thickness. They dry rapidly and display a high degree of water resistance, without being indelible. These inks are highly sought after for calligraphy, quill drawings, washes, for textile creations and materials research.
