A more thorough explanation:

MASSA

Massa is a Latin word that refers to a lump or mass of metal, particularly gold or silver, before it is shaped into a useful or decorative object.

Example 1: The goldsmith melted the massa down to create a beautiful necklace.

Example 2: The silversmith used a hammer to shape the massa into a bowl.

The examples illustrate how massa is a raw material used by metalworkers to create beautiful and functional objects. In example 1, the goldsmith takes the lump of gold and melts it down to create a necklace. In example 2, the silversmith uses a hammer to shape the massa into a bowl. Both examples show how massa is the starting point for creating something valuable and beautiful.
