1) Any functional or utilitarian object, old or new,
which has been restored or conserved in any way should revert to decorative display only.
Adhesives, paints, and fillers used in their repair are easily degraded by warm liquids,
foodstuffs, or detergents and may be toxic if ingested.
2) Soft bodied ceramics including soft paste porcelain, earthenware and archaeological
ceramics may be bonded with a water-soluble adhesive. This adhesive will dissolve or
soften if the object is washed or soaked in water resulting in separation. To be
safe, all restored objects should only be cleaned with a damp cloth or dusted with an
artist brush. Once repaired, inquire of your restorer or conservator about the conditions
of aftercare specific to your object.
3) Because all restoration and conservation involves the use of synthetic materials and
not original clay, glaze or enamel, their aging characteristics are quite different from
the relatively inert ceramic materials. The problems of yellowing paints, fillers and
adhesives are accelerated by the presence of ultra-violet light. This exposure can be
reduced by display out of direct sun- light and installing ultra-violet filters on indoor
lighting. To insure the longevity of a repair, temperature and humidity extremes should
also be avoided in storage or display.
4) Any objects restored with over-spray or heavily retouched with the common melamine
urea formaldehyde paint medium should not be stored in the dark for long periods of time
as they may quickly yellow. Over-spray restoration is the most problematic of all repairs
and has inherent aging problems due to the extent of "over" restoration
extending beyond the area of damage.
5) Avoid handling objects by their handles, rims, finials or sprigged
attachments as there may be firing faults, hair-line breaks or previously bonded with
adhesives weaker than the ceramic, all of which may fail.
6) Avoid the use of metal spring loaded plate hangers if the piece has been rebonded or
has hairline breaks. The pressure exerted across the back face of the plate may separate
the old break. Easels or springless plate hangers are preferable in any case. Cushion
metal hangers with plastic tubing to prevent chipping at the rim.
7) Accession numbers should be applied in discreet areas over a reversible acrylic base
coat. Collection stickers or tape should not be placed over enamel, luster, gilt surfaces
or restored areas as damages may result when removed.
8) Any objects which exhibits efflorescence or flaking glazes should be kept at a
constant relative humidity of 40%.
