This antique lamp shade
had been stored
since a hobbyist unsuccessful
had tried to
repair it 20 years ago.
It semed to be a
hopeless case to the owner.
Here is what we got:
Due to the enormous damage
we decided
to rebuild the entire shade.This
requires a new
360 degree lamp mold. Most
important here is
the correct size and shape
of this new mold.
It has to match perfectly
with the old original
lamp mold of Tiffany Studios,
on which this
shade was produced about
90 years ago.
We use some silicone, to
get the right shape :
The lower aperture rim of
the old lamp shade
has the 1:1 information
for the correct
diameter of the new lamp
mold. Herfore
we remove it from the shade
and rebend
it to it`s former
(perfect round) shape.
Before doing this, we have
to remove
the Tiffany-Studios signature
tags.
We will resolder them later
into the right place,
when the lamp shade has
been rebuilt.
Here the lower rim is heated
carefully and
removed from the lamp........
......for cleaning it up.......
......and rebending
The silicone key is the stencil
for creating
the new mold's correct shape.
This is the draft for the
new mold...........
....which is made from
plaster to be duplicated by my
fiberglass company after
it has been polished.
The fiberglass mold is completed
here and
some of the original
glass pieces (which were
included with the lamp)
indicate that the shape
is correct. The original
lower rim also fits perfect.
The lamp shade can be brought
to new
life on this fiberglass
mold.
Here the original pattern
is scribed on the mold.
We have engraved the lines
and transferred
the pattern on paper.This
will be used for our
360 degrees layout we need
for our Studios
light table later.
