Note 74 — Chapter XIII · ON CARDINALS’ SEALS.
C. R. (Charles Robert) Ashbee translation
This, which is the ordinary cire perdue process, is again described in Chapter XXII., where Cellini deals with a vase he is making. The accompanying diagram illustrates it in its application to seals. The mouth or ingress hole, or what will become the mouth, is rolled in wax and attached to the top, the two vents are rolled and attached in a similar way below, but so as not to touch the pattern.
