Abstract
The aim of this work is to examine cysteine as an alternative to
benzotriazole (BTA) for the conservation of archaeological objects
with bronze disease. Investigation of the two inhibitors involved the
use of electrochemical techniques, measurements of weight change
in high humidity and comparative studies of colour changes in the corrosion
products. The results obtained in this article demonstrate that
cysteine could be a non-toxic alternative to BTA. Cysteine performed
as well as BTA on pre-corroded coupons with bronze disease in high
humidity and showed acceptable results during testing for colour
alteration on real archaeological objects.
