For curved surfaces, as cylinders, any of these methods can be used;
the plasticine is the more successful.

In all casting of plaster on a small scale, use a soft camel-hair
brush. Mix the plaster in the palm of the hand with a knife, take up
some of the wettest to brush over the face of the moulds (a dozen
scarabs or small coins done at once); then put he brush in water, and
take up thicker plaster with a pocket-knife to drop on as a backing.
This avoids air bubbles without using too weak a plaster.



Copying hieroglyphic inscriptions.
Where possible a wet or a dry squeeze should be taken of any
inscription. When hand copying is necessary, the main matter is to
get the cartouches of king's names accurately, and the date at the
beginning, examining specially whether single strokes, I I I I, have
been connected above, n n, forming the ten sign. The main difficulty
for any one not knowing the 800 signs is to distinguish between those
that are alike, especially when damaged. For this purpose the
commonest signs that may be confused are here placed together, so
that the essential points of difference may be noticed. A small cross
is placed here by small points of distinction which might escape
notice.
