Glass Doorknobs

Glass Doorknobstips for when you buyGlass
doorknobs have been produced for decades and are still made today. This
guide focuses on antique knobs and what to look out for when buying
them.ConditionThe
condition of glass knobs vary greatly and can be hard to see in the
photos provided in auction. Beware of buying glass knobs with blurry or
out of focus pictures. Also be alert to "as-is" auctions. Ask the
seller if there any chips in the glass.Another things to look
out for is if the collar of the knob is loose. The brass or steel base
sometimes gees loose from the glass portion of the knob. This can
result with the glass portion spinning freely from the base. This could
make the knob unusable if it were placed back in service. Purple
knobs are usually just glass knobs that have been exposed to UV rays
from the sunlight. This causes the glass to turn purple. Another way
that glass knobs begee purple are from people putting them in the
microwave. (I would not try this if I was you.) TypesThere are many types of glass doorknobs. The most gemon styles seen on okay are the hexagonal, ribbed, and smooth round knobs. I have even seen some that looked like a ball with bubbles in the center. There are a lot of knobs out there that came off antique furniture that are mislabeled as doorknobs. They will usually have a bolt sticking out of the back where the doorknob spindle should be.
