Each piece of Shirley Pewter is a
hand-crafted piece of art. Every item is created using
time-honored methods of pewtering which have been passed down
from generation to generation. Several elements go into
forming an item of quality and craftsmanship. Design, form,
construction, and finish are the true gauges of the
craftsman's hand and the quality of his product
The properties of pewter are such that the metal can be
worked in a number of ways. The two traditional methods of
crafting the material are casting, and manipulation into forms
from flat sheet metal.
Pouring molten pewter into a
mould.
In casting, molten metal is poured into
gunmetal moulds producing a single form, or into centrifugal
casting machines, allowing for multiple castings of small
items from a single rubber mould. Moulds of cuttlebones,
plaster, or the lost wax process can produce a single unique
casting. Following the rapid hardening of the metal, craftsmen
must prepare pieces for polishing. Cleaning may involve using
hand files to remove seams, or turning which is mounting the
item on a lathe and removing thin layers of metal with cutting
tools.
Joining and soldering components to
finalize the form...
Soldering is the standard method of attaching
pewter components. The pieces to be joined are heated, and a
tin based alloy is applied. Under capillary action the molten
material is drawn between the pieces, cools and hardens. Flux
is used to remove oxides during heating.
Buffing & polishing, the last touch
to highlight the beauty...
The beauty of pewter is often enhanced through
polishing. The pewter item is pressed against rapidly rotating
buffing wheels made of felt with varying abrasives or rouges
being applied. The purpose of buffing is to remove surface
imperfections. Some polishing takes place on pieces before
assembly if areas on the item would be hidden during final
polishing.
Shirley Pewter is routinely finished with a high luster
polish, however a satin finish can be achieved through coarse
abrasive and steel wool, creating the brushed effect. Pewter
from earlier periods oxidized easily due to high lead content.
In order to simulate antique pewter, chemical treatments may
be applied which "oxidize" or darken the surface permanently.
Spinning, an art on the
lathe...
Spinning is a metal forming process which occurs on
a lathe and by which hollow pewter vessels are created from
flat stock metal. A disc of metal is mounted against a chuck
or mandrel - the form to be achieved - and then while
rotating, pressure is applied to the metal by hand tools so
that it conforms to the shape. Once the desired shapes has
been attained a skilled spinner smoothes the surface of the
vessel with an ironing type movement of his tools so as to
remove any tooling marks. Pot bellied forms are created
through the use of slit chucks. The slit chuck is assembled to
create the form. Pewter is spun over the chuck, then each
piece of the chuck is removed...like a puzzle.
Functionality, care and long
life...
Shirley Pewter is produced from a pewter
alloy made up of 92% tin, 5% antimony and 3% copper. All
Shirley Pewter products are quite safe to use in contact with
food and drink. Shirley Pewter is essentially "Lead Free," it
occurs only as a trace element in the pewter. The beautiful
appearance of our pewter requires surprisingly little
maintenance.
