WHAT IS P’CLAY™?
Any clay body with paper pulp added. |
WHY P’CLAY™?
Because paper pulp does incredible things to clay! |
The addition of paper pulp to
clay distributes extremely fine paper fibers throughout the
body that serve two basic functions:
(1) creates a strong but flexible INTERNAL STRUCTURE in the clay
(2) creates a “CAPILLARY SYSTEM” that transfers moisture easily and
evenly throughout the clay. |
Some of the results are:
- Incredibly strong slabs
— even extra thin slabs will fold, bend and drape without tearing
- Extra large/thick forms
hold up under their own weight
- Greenware re-wets easily
and evenly allowing you to:
— re-work, alter and add new clay at any stage of dryness
— build an “armature” and allow it to dry as a support for
sculpture that need not be removed for firing
- Moisture “wicks-out”
of P’ClayTM so evenly that pieces can be force-dried with excellent
results.
- Exaggerated forms hold
their shape*
|
- Greenware - even bone
dry - is unbelievably strong: easy to handle and transport if
necessary
- Make P’ClayTM into a
“putty” to repair cracks in greenware or to construct forms out of
previously made “modules”. You may even repair or add to already
bisqued P’ClayTM (re-bisque pieces after making alterations for best
results) (*be careful not to get too extreme: once bisqued, the fiber
structure burns out and slumping may occur if the base-clay is
over-fired)
|
|
In addition, the “burn-out”
of the paper fibers results in a noticeably lower fired weight
especially in large-scale works and the resulting “open-ness” gives
improved thermal shock properties to most P’Clay™ Bodies.
Tucker’s mixes and tests its P’Clay™ with the same high standards
of quality control that they apply to their regular clays. ( A
preservative is added to P’Clay to prevent excessive mold-growth due to
the paper content, but some is to be expected.) The P’Clay™ we carry
is considered Sculptor’s P’Clay™ but may be used for
throwing, however, it will be difficult to trim (in the traditional sense)
as the fibers will get caught in most trimming tools, Other forms of P’Clay™
are possible and may eventually become available through Tucker’s — we
will keep you posted. You may order custom clays bodies with additions of
paper pulp (the same 1320 lb./30 box minimum applies).
*** 2
final notes:
1)
Bisque firing
P’Clay™ will produce a “smoking period” while the paper fiber
burns out - kilns
must be well vented!
2)
The paper
pulp used in P’Clay is an organic material and will in time become
moldy. A food-grade preservative is added to the P’Clay to slow the
growth of this mold; however, it cannot prevent it. Because of this, we
try to limit our stock to keep it as fresh as possible and recommend that
our customers do the same. The mold does not effect the properties of the
clay (it actually makes it more plastic) and it will burn out
during firing. It is, however, unattractive and may cause problems for
people who are allergic or sensitive to mold. (Moldy P’Clay is not
returnable.)

Mid
Smooth Stone P’CLAY™ C/6
Tucker’s very popular, smooth mid-range stoneware was originally
designed for throwing and contains no coarse grog or fireclay. The
inclusion of 5% 110-mesh silica sand in the original formula
allowed this clay to handbuild on a small scale. Now, the addition
of paper pulp makes it ideal for sculptural work by improving its
building and drying properties without changing its clean surface.
Mid Smooth Stone P’ClayTM still fires to a lovely creamy white @
Cone 6 keeping glaze colors bright and true. |

Originally a super throwing clay with a small amount of fireclay
and 5% (30x80)-mesh grog. Now, with addition of paper pulp, it is
an excellent sculpture body. This P’ClayTM is the best suited
for large scale work due to its combination of clays, grog content
and fibers. Fires a Stoney grey in Reduction and a lighter grey in
Oxidation. |
