USEFUL INFORMATION - Protecting your Collection
The following information is provided by way of general guidance only and is not intended to be definitive. Readers are advised to seek professional advice via, for example, the Useful Links included.
Maintain an Up-to-Date Inventory
Official Appraisal & Valuation
Depending on the value of your collection, the best advice is to engage an independent, qualified appraiser to fully document and value your collection. The more valuable the collection, the wiser this is.
Or, at the very least, prepare your own Digital
or Paper Record
Take a digital image(s) of each item (the higher the resolution the better)
and save to CD or photograph with other camera and colour prints. Prepare
a description of each item, the more detailed the better but definitely
including the type of object, the medium or material, dimensions, condition
of the piece, where and when purchased and any other provenance - with
original receipts, documents of authenticity etc.
File a copy in a separate location outside your home: for example, at your solicitors or bank.
Some Useful Do’s and Don’ts
Works of art are vulnerable to many risks, some obvious, others less so:
Do
Frame all art with ‘museum quality’ framing materials
This applies especially to works on paper, textiles and photographs.
Ultraviolet (UV) glass will also help protect pictures from fading
(and thus reducing their value).
Think where to hang a work before you do so
In order to prevent accidental damage.
Display at eye-level
Most pictures are intended to be viewed at eye-level. When hanging a
number of works it is useful to arrange them on the floor first.
Take care when affixing to a wall
Use two hooks on the wall, each set about a quarter of the way in from
either side of the picture. Check that the cord, wire or other hanger
is designed to support the weight of the work. It is wise to take professional
advice where safety is critical as, for example, when hanging a work
in a child's bedroom.
Beware heat
Extreme or rapid changes in temperature cause paper and wood to warp
or dry out and adhesives to fail. It is best to try to maintain your
home at a constant temperature of approximately 20 degrees Celsius
(plus or minus 3 degrees) and 55% relative humidity (plus or minus
5 degrees). If your home thermostat is imprecise, you can purchase
a digital thermohygrometer (which measures temperature and air humidity)
relatively inexpensively, at about £20.
Beware damp
Attics and cellars are particularly susceptible to extreme or rapid changes
in temperature and could be prone to flooding or other water leaks.
Avoid hanging framed pictures in such conditions as damp can cause
them to ripple, and encourages fungal growth. It is best to allow six
months before hanging pictures on newly plastered walls.
Use smoke detectors rather than heat detectors
As smoke damage can result before heat build-up is detected.
Handle and store with care
When carrying and transporting a picture, hold the frame firmly on both
sides. When storing pictures, stack them vertically, the right way
up, and 'glass to glass' (so that fixings on the reverse do not damage
the frames).
Clean gently
Dust frames with a soft brush and do not apply water or cleaning
fluids, especially on the varnished surface of oil paintings (just dust
carefully).
Keep undisplayed works in a lockable cupboard
Wrap items as safely as possible. Stack framed items vertically, the
right way up, and ‘glass-to-glass’.
Consult qualified professionals
Install a reliable home alarm system
Ensure your contents insurance reflects current market value
Don’t’s
Don’t (ever) hang paintings or any other work in direct
sunlight
Direct sunlight, as well as natural light, can cause severe damage, especially
to works on paper, textiles and photographs: and this damage is usually
irreversible. Whenever possible, keep blinds or curtains drawn and turn
off all lighting in rooms that are not in use. Ultraviolet (UV) window
glass and/or picture glass will help but may not eliminate the problem.
Don’t hang paintings above radiators or chimneys/fireplaces
Extreme or rapid changes in temperature and smoke can affect the surface
of a painting, cause paper and wood to warp and dry out, and adhesives
to fail. Avoid hanging pictures directly above radiators and fireplaces/chimneys
in use can dry out a painting from the back.
Don’t use picture lights
Damage can result from light focussed on a particular spot on a picture
and from frequent changes in temperature as the light is switched on
and off.
Don’t store pictures or any other artwork in cellars or
attics
Both are rarely climate- or damp-controlled, are subject to dramatic
changes in temperature, and could be prone to flooding or other water
leaks.
Don’t use water or chemicals
Water, cleaning fluids or other chemicals can damage pictures, frames
or other artworks, especially on the varnished surface of oil paintings.
Just dust with a soft brush or cloth.
Don’t hang a painting or display a work in a location
visible from the street
As this could encourage theft.
