Trassista

Trassista is a term that may refer to a person who works with trass, a porous volcanic rock used as a pozzolanic material in cement and lime production. The form appears in languages that form agent nouns with the suffix -ista, but it is not a widely attested occupation in English-language sources. Because of its uncertain usage, trassista is best understood as a historical or regional designation rather than a standardized job title.

In historical contexts, a trassista might have been a quarry worker, processor, or technician involved in extracting, grinding, testing, or blending trass for use in binders. Trass was valued for its reaction with lime to create durable mortars, and industries in parts of Central Europe and the eastern Mediterranean exploited trass deposits before modern synthetic pozzolanic materials became prevalent.

In contemporary references, the term is rarely used. Professionals who work with similar materials are usually described by specific roles such as geologist, mining technician, mineral processor, or cement technologist. The occurrence of trassista can also appear as a surname in some regions.
