It is always desirable to make several castings of the same object, as the moulds are apt to get chipped when laid by in a cupboard; and for this reason, as well as for the sake of practice, we recommend our pupils to make at least a dozen waxen eggs before they proceed to any other object. If they succeed in this

completely

, they may rest assured that every difficulty which is likely to meet them in any future operation will be easily overcome.

2546. Colouring the Wax

While the wax is yet on the hob, and in a fluid state, stir into it a little

flake white

, in powder, and continue to stir the mixture while it is being poured into the half mould. It will be found that unless the fixing and shaking of the moulds is managed quickly, the colouring matter will settle on the side of the half into which the mixture is poured; a little care in manipulation is therefore again requisite. The colouring of the wax is a matter which comes easily enough by experiment. Oranges, lemons, large gooseberries, small cucumbers, &c.,&c., are excellent objects for practice.
