What is a Masonic Fire?

The provided sources do not explicitly define or name "Masonic fire," though they describe the structured traditions of ceremonial toast-drinking and table lodge festivities from which such practices derive.

In early lodge banquets and Table Lodges, toasts were governed by strict ritual and executed in unison 1. Brethren stood and observed the Master's motions before drinking 1, or accompanied a health with stylized acclamations, such as "three claps and three hussas" 2. French Table Lodges maintained formal Santés d'obligation (obligatory healths) subject to prescribed ritual movements 1, and certain Continental observances included ceremonial actions like emptying a glass in due form and shattering it 3.

The supplied passages detail these formal toast-drinking customs, claps, and obligatory healths, but they do not set out the specific definition or origin of the term "Masonic fire" itself.
