Repairs:- Updated 01/04
Locating pot lids at any time is difficult. When they do
turn up excitement, jubilation and a reach for the checkbook tend to
overtake fair judgment. Age and the material of manufacturer dictate a large
percentage of this particular collectable are probably dug and damaged.
Usually damage is to the outer areas with the rim and lip areas being
repaired reasonably easily. Be sure to check these areas first when looking
at any new purchase. Many an article has been published on how to create a
mould and repair minor damage reasonably easily. On many occasions damage is
minor so always check under the price sticker or auction number, a frequent
place for deception.
Repairs come in a number of forms. These are normally
pursuant to the rarity of the lid and the cost to perform adequate
restoration.
The more common lids can be repaired via a plaster of paris or
similar material copying the contours of the lid and applying a filler.
Simple economics warrants further action and achieves a reasonable
restoration, undetectable by most. At the other end of the scale are
professional repairers of fine china who repair shape coupled with graphic artists who
repair the transfer. The resulting is then re-fired making detection
almost impossible. With this in mind, how does one spot repairs?
A method that has worked well for me is from the outset
consider every lid offered repaired or reproduction. Subsequent observations
should be made to prove otherwise. First of all run a fingernail over the
face and sides of the lid looking for repairs. Irregularities pointing to
crude repairs are discovered easily in this manner and these being the most
common areas of repair. It is most difficult to maintain the contour
and antique glaze crazing once repaired. Always carry a magnifying glass and
ultraviolet light. Most genuine pot lids are over 100 years old and all have
some degree of crazing. That is minute cracking un the glaze. It is often
easy to repair but impossible to reproduce this aging. Examine the lid
closely fully and ensure the crazing is consistent. After checking the
glaze is consistent the use of ultra violet light comes into play. The use of
this tool is a subject in its own. Despite the following lid being sold as
original. the below shows a world of difference under ultraviolet.
NB:- Some modern reproductions attempt to copy
crazing by opening the kiln door early and cooling quickly. In this case crazing appears greatly
expanded than normal. Examine known old lids to get a feel of what is
expected from an antique.

Depending on the light used a number of outcomes are
possible. Viewing the above, despite being totally white in normal light this image
shows an obvious area of repair and the lighter areas surrounding are of a
finish applied (these days usually urethane) to waterproof the repair.

Stepping up the detection of repairs to the technically
inclined, the above is something I found recently playing with images for
this website. Adjusting the various base color channels and saturation can
display aspects that the naked eye cannot. May well be time to trade in the
traditional collection of purple lights to a basic digital camera? This
particular image retouch was done via adjusting Cyan +20% and reducing
Magenta and Yellow 80% in Photo impact, a particularly good image
manipulation program for under $80. Depending on the image these values will
most certainly change however give it a shot, this concept is new.
Particularly useful reviewing online auction items listed with oversize
images!!!!
I cringe when a seller tells me they have bathed a
lid in bleach for a quick clean up. Be ware the pink tinge! Plenty of horror
stories out there of those who did not get the mix quite right or the poor
old end purchaser who went to check on the investment a few years down the
road and found a pile of white dust. Unless you are a distinguished
industrial chemist with deep pockets just don't attempt. The following is
the perfect example of what can happen. Yep, got rid of that rust BUT !!!!

Any new lid I purchase has a couple of months in water
as a security blanket.
Firstly to identify unreported repairs but more importantly to flush
out any chemicals that my destroy the lid as time goes by. It is important to
change the water regularly to leach any impurities and view with HP paper or
similar to ensure neutrality. Most pet stores have this paper or chemical
drops that achieve the same.
This process sounds like a lot of work however one of the
most common house hold utilities can help. The toilet system tank is a
convenient
destination for immersion. (Be sure to warn the wife to cease use of those
blue lou tables during cleaning to guard against some unwanted variations,
been there done that) Every flush changes the water and aids in
cleaning. On inspection those
leaching chemicals usually exhibit small lumps indiscriminately
across the lid. If this happens it is important to prolong the process and
measure there after in a more defined manner. Promote this lid to immersion
into rain or distilled water and measure the PH regularly changing the water
until neutral. |
