I may need some tar remover and a place to put the feathers, but here goes~
I recently made the acquaintance of a gentleman in the State of
The concept behind cleaning is simple; a bottle which was
once in pristine condition has been buried in soil. The minerals, acids and or alkalis
in the soil react with the components in the glass and an exchange takes place
whereby the previously bright and sparkly glass becomes opaque at best, or
etched at worst. This process has been generically referred to as "opalization"
over the years. Simply, the bottle is no longer in it's original state and is
unattractive to look at.
In the old days, (1960's - 1970's) a wet cotton
wheel attached to a washing machine motor was used and grits of varying grades
were combined to make a slurry which was applied to the cotton wheel. Once this
was done, the bottle was ground away on in hopes of removing the stain. This constantly
resulted in bottles that had the embossing all but worn off and broken bottles due to excessive friction and heat. Thank God those days are apparently long gone.
The particular machine used by this person was made and
marketed by Mr. Wayne Lowry, also known as the "Jar Doctor". At first
glance one can see the quality and attention to detail put into this machine. It
features easily adjustable rollers that accomodate different sized cylinders to
allow different size and shape bottles to be cleaned. According to what I was
told, the process is simple. The base "stopple" has fingers that grip
the base of the bottle when it is inserted into the cylinder. The bottle is
first loaded with fine pieces of copper wire and powdered oxide. Water is added
to the inside of the bottle just above the copper. The bottle is inserted into
the cylinder and the mouth plugged temporarily to allow addition of more copper,
oxide and water to the inside of the cylinder without adding more to the
bottle. Once this is done, a "cone stopple" is inserted into the
mouth of the bottle and the cylinder is sealed by use of a compression gasket
and wing nut. The cylinder goes onto the rollers and a switch gets flipped to
begin the process. The cylinder ends get reversed about twice a day in order
to change the direction of rotation. This allows the copper and oxide to get
into every recess and avoid over cleaning in either direction. After a period
of time ranging from one to three days, depending on the amount of stain
present and hardness of the glass, the switch is flipped off and the cylinder
opened up. The slurry is rinsed off of and out of the bottle using tepid water and
the bottle is gone over with a quick rub down of soft scrub outside and ammonia
inside to remove any remaining traces of oxide. Assuming that all went
according to plan, the "opalization" is gone and the bottle now looks
exactly as it did before being tossed out with the garbage, a century or more
before. According to this person, he's never broken a bottle.
Apparently, the learning curve of modern bottle cleaning is
challenging at best. Early black glass from the Gold Rush era of 1850 differs
in composition and hardness compared to say a San Francisco whiskey dating from the 1870's
or 80's. And, "tap*tap - no erasies" is the rule of the day when you screw up. As
such, it's often a good idea from both a cost and risk standpoint to solicit
the services of a professional. Lou Lambert, and a few others out there have
elevated modern bottle cleaning to a science. My hats off to those that have
expended the time and energy to perfect bottle cleaning in the 21st century!
It does go without saying that once it's time to move a bottle
along, the potential buyer must be made aware of the fact that it has been
cleaned; that's just common courtesy.
The vast majority of the collectors that I associate with would much prefer to own a bottle that has been cleaned compared to one that is so sick that it belongs tucked away in a box. Based on my observations, there is no question in my mind that done properly, bottle cleaning is ethical and does nothing to alter a bottle; it simply restores it 's appearance to pre-disposal condition. Furthermore, it preserves a piece of history that we can all be proud to own instead of having to make excuses for.
Thanks to what I've recently learned, I think that it's a travesty to leave a good (but stained) bottle stuffed away when it can be restored to as new appearance and be proudly displayed for all to enjoy.
