Lant Explained

Lant is aged urine. The term comes from Old English, which referred to urine.[1] Collected urine was put aside to ferment until used for its chemical content in many pre-industrial processes, such as cleaning and production.[2]

History

Because of its ammonium content, lant was most commonly used for floor cleaning and laundry. According to early housekeeping guides, bedpans would be collected by one of the younger male servants and put away to ferment to a mild caustic before use.

In larger cottage industries, lant was used in wool-processing[3] and as a source of potassium nitrate for black powder. In times of urgent need and in districts where these were the chief industries, the whole town was expected to contribute to its supply.

LaNt (with an alternate capitalization) may also refer to Laminin N-terminus proteins.[4] Laminins are basic structural proteins of basement membranes. Some particularly small sized proteins within this family of proteins are called LaNt proteins.
