        Tattletale Surface Identifies Doorstop as a Reproduction    

The Making of a Doorstop
Step 1 -- The artist would carve a design in wood
or a sculture a model in plaster
Step 2 --Using 2 boxes full of sand, the figure's outline
is captured by pressing it in the sand between them
Step 3 -- Molten metal ore is poured into this cavity of sand
Step 4 -- The resulting metal casting would be hand filed & buffed.
Now, this smooth metal figure becomes the pattern.
Step 5 --The pattern's outline is captured by pressing it in sand
Step 6 -- The boxes of sand are hardened with heat and/or chemical solutions
2 mold halves become a permanent mold able to produce many doorstops
Step 7 -- Molten iron ore is poured into the permanent mold
Step 8 -- The resulting casting becomes a doorstop
The Reproduction skips steps 1 thru 4
and uses an expensive doorstop
(one that has no value due to its condition)
as the pattern for step 5

"Beware if Grainy"

Since Reproductions are made from "Molds made of Sand".
When a molten metal is poured in the mold,
naturally, some of the grains of sand will be
fused in the surface of the casting.

A hundred years of wear has also produced a very
Smooth Surface for the original old Doorstops.

On some forgeries of poor quality you are able
to detect this sand on the surface by gentley
rubbing your hands over the doorstop in question.
You can actually feel the grains of sand or
a roughness on the surface.

Sometines, by Eyesight, you can even detect this surface.

The below Picture is a good example
of a Grainy Surface of a Reproduction.
