Gamboge Orange

: ON THE SECONDARY, ORANGE.

On adding acetate of lead to a potash solution of gamboge, a rich bright

orange is precipitated, which may be washed on a filter till the

washings are colourless, and preserves its hue with careful drying. The

orange which we thus obtained stood well in a book, but it cannot be

recommended as an artistic pigment. Perhaps in dyeing, the lead and

gamboge solutions might be worth a trial.
