Alumina Hydrate Light
Starting at: £8.30
Alumina Hydrate is an inert pigment with highly absorbent properties, which can be ground into oil paint as an almost colourless extender. It is often used as an additive in commercial oil paints, particularly in conjunction with transparent or lake pigments, as it provides stability and a homogenous consistency without effecting colour or gloss, although it may effect the pigment strength. When combined with linseed oil, it produces an almost transparent painting medium for extending oil colours. Sometimes referred to as Lake Base. Learn More -

London Pigment, Rotherhithe Orange Pigment
£20.00This unique colour is an intense orange oxide that is made from the decay of Victorian pipes mixing with the chalk bed of the infilled docks at Rotherhithe, in south east London. Rotherhithe has a long history as a port, with many shipyards from Elizabethan times until the early 20th century and with working docks until the 1970s, when they began to be infilled due to a decline in imports to Central London. With a fine particle size and transparent quality this pigment would be great for glazing techniques.
