In , what is the difference between Chinese White and Titanium White as far as transparency is concerned?
Chinese White is actually a compressed form of Zinc White, which is relatively transparent and therefore good for scumbling (putting a semi-transparent layer of paint over another - not always easy with large areas of watercolour, as there is usually the probability of re-dissolving the lower layer of paint).
Titanium White is opaque (owing to its high refractive index - which makes it extremely good at scattering light), it is the white that we have chosen for our own watercolours.
