Wolfs Conservation and Restoration

Object:
A Dutch early 20th century vase made in the Plateelbakkerij Zuid-Holland

Approximate size:
Diameter ca. 35 cm. 

Condition:
The object was deteriorating fast due to soluble salts. In this type of deterioration, salts accumulate behind the glazed surface and recrystallize with increases in volume due to absorbed water and water of crystallization. The mechanical forces produced by these recrystallizing salts can ultimately detach the glaze from the underlying ceramic body; as was clearly seen on this vase. 

Treatment carried out:
Some fragile glaze had to be temporarily consolidated so the vase could be desalinated. 
After desalination the damaged areas were consolidated, filled and then retouched.
