BEFORE TREATMENT: FRAGMENTS OF PHOTOGRAPHS SHOWS CORROSION OXIDIZED CAST IRON THAT GOES THROUGH
ELECTROPLATED COPPER ON TOP OF IT
ELECTROPLATED COPPER ON TOP OF IT
DECOMPOSITION OF PREVIOUSLY RESTORED AREAS
BEFORE TREATMENT: DETERIORATION PLATING MANY AREAS OF SCULPTURE SHOWS THAT OXIDATION OF IRON EAT AWAY

IN PROCESS: SHOWN TESTS ON CLEANING SURFACE OF OXIDIZED COPPER AND IRON, ALSO REMOVAL DETERIORATE
PEACES OF PREVIOUS RESTORATION

SCULPTURE IN PROCESS OF TREATMENT: CHEMICALLY AND
MECHANICALLY REMOVAL ALL DETERIORATIONS
MECHANICALLY REMOVAL ALL DETERIORATIONS
INSERT MULTIPLE STEEL RODS TO SUPPORT structural integrity

CONDITION OF BASE BEFORE TREATMENT
AFTER TREATMENT: LIKE YOU CAN SEE IT WAS
NOT EASY TASK. YOU CAN NOT WELD AGED CASTS
IRON BECAUSE DIFFERENTIAL OF TEMPERATURE
WITHOUT PREHEATING CAN DAMAGE IRON IN
DIFFERENT PLACES . SO WE HAVE TO FIND OUT A
WAY TO AVOID CRUMBLING MATERIALS AND
STRUCTURALLY SUPPORT WEIGHT OF THE
SCULPTURE. AFTER SUCCESSFUL TESTING
SCULPTURE WAS CLEANED FROM OXIDATION AND
DETERIORATION OF OXIDES . A SURFACE WAS
REPATINATED, DAMAGED ARES OF PLATED
COPPER WERE COMPENSATED AND FINALLY
SEALED.
