Historical Definition
Martath, or Martach, is litharge.
Meaning
The entry supplies alternative spellings and one material equivalent. Neither spelling receives an independent description of composition or preparation, so their separate appearance in a text need not imply separate ingredients.
Use in the Book
Lethargyrium gives a fuller account of a scum separated while metallic materials are purified. Its range includes mercury, silver and lead; that wider definition should be consulted rather than silently narrowed on the strength of a resemblance between the names.
Places to Read
Lethargyrium. A separated scum from the purification of three named metallic materials.
