Abstract: | Adherent deposits are very aggressive towards ancient heritage paintings since they affect the varnish and
the painting’s layers, sometimes reaching the preparative layers. The biggest problem to the restorer is
their removal without affecting the patina, the transparent varnish (well preserved) and fine colour glazes
made during painting. Therefore, their removal requires preliminary cleaning tests that allow the optimization
of the cleaning system composition that is going to be used. The study was focused on organic
natural systems, as colourless supernatants, some of them used during ages, but insufficiently studied.
The paper presents an evaluation of the effectiveness of cleaning varnished icons of the nineteenth century,
with complex conservation cases using supernatants derived from aqueous dispersions extracted
from vegetables and dry indigenous herbal infusions. Best results, after six consecutive cleaning steps,
on tempera old icon was obtained for a mixture made of mature white onion juice + extract of Soapwort
flowers + corn silk tea + acacia tea. As a best result after just one cleaning step was obtained for a quaternary
mixture composed from mature white onion juice + mature carrot juice + corn silk tea + aqueous
extract of Soapwort flowers. |
