2539. Making the Moulds—First Half
Having filled a small pudding basin about three-quarters full of damp sand (the finer the better), lay the egg lengthways in the sand, so that half of it is above, and half below, the level of the sand, which should be perfectly smooth around it. Then prepare the plaster in another basin, which should be half full of water. Sprinkle the plaster in quickly till it comes to the top of the water, and then, having stirred it for a moment with a spoon, pour the whole upon the egg in the other basin.
2540. Making the Moulds—Second Half
While the half mould thus made is hardening thoroughly, carefully remove every particle of plaster from the basin in which it was mixed, and also from the spoon which has been used. This must be done by placing them both in water and wiping them perfectly clean. This is highly important, since a small quantity of plaster which has set will destroy the quality of a second mixing if it is incorporated therewith. In about five minutes the half mould will be fit to remove, which may be done by turning the basin up with the right hand (taking care not to lose the sand), so that the mould falls into the left hand.
The egg should then be gently allowed to fall back on the sand out of the mould; if, however, it adheres, lightly scrape the plaster from the edge of the mould, and then shake it out into the hollow of the hand. If, however, the exact half of the egg has been immersed in the sand, no such difficulty will arise; this shows how important is exactness in the first position of the object from which a tasting is to be taken.
The egg being removed and laid aside, the moulder casting must be "trimmed;" that is, the sand must be brushed from the flat surface of the mould with a nail-brush very slightly, without touching the extreme and sharp edges where the hollow of the mould commences. Then upon the broad edge from which the sand has been brushed, make four equi-distant hollows (with the round end of a table-knife), like the deep impression of a thimble's-end. These are to guide hereafter in the fixing of the second half of the mould. The egg should now be replaced in the casting, and the edge of the cast, with the holes, thoroughly lubricated with sweet oil, laid on with a feather, or what is better, a large camel-hair brush.
