Resumen:
On March
13, 1770, as a consequence of a storm the british war corvette H.M.S. SWIFT
strand and sink at the Patagonian coast in the Deseado Ria, Santa Cruz, Argentina, at 50 meters of the coast.
In 1982 a group of young enthusiasts initiated the search and rescue of the Swift objects.
At the next
year, 1983, The Museo Municipal Mario
Brozoki is created ( Puerto Deseado,
Provincia de Santa Cruz, Argentina) who is in charged of the rescue and
conservation of the pieces, in collaboration with the Instituto Nacional de
Antropología de la Argentina.
Up to now
more than 500 pieces were rescued. Many of them have marine corrosion and
concretions that make impossible determine by simple inspection, their
constitutive materials.
Before
restoration and conservation it is necessary to identify the composition of the
substrate to decide the treatment.
In this
work LIBS analysis and laser cleaning were applied to a collection of metal pieces rescued from the SWIFT.
