Porcelain and Stoneware Enhancer


APT-II PORCELAIN / STONEWARE ENHANCER INSTRUCTIONS

APT-II Enhancer is an acrylic emulsion additive that is food safe and non-toxic.  It cleans up with water and has an indefinite shelf life.  Usage techniques and firing methods are not altered.  PROTECT FROM FREEZING.

          APT-II Enhancer will thicken all brands of slip and clay bodies, enabling the ceramist to attach, mend and create surface decorations.  This process can be performed on greenware and bisque.

APT-II PORCELAIN / STONEWARE ENHANCER CREATES A BETTER SLIP MENDER:

q       Bonding occurs immediately.

q       Mended area dries to the same softness as the greenware.

q       Mended area may be cleaned immediately.

q       Mended area does not shrink and leave a stress crack.

q       Colors and glazes adhere to mended area without showing a difference in color.

q       Slip mixture will adhere to glaze fired surfaces.

q       Slip mixture will not produce odors or acid fumes in kiln.

   PREPARING  -  *SLIP MIXTURE
For Mending and Attaching

·        Pour fresh slip into container.

·        Add APT-II Porcelain/Stoneware Enhancer into slip until it begins to thicken to a consistency of cake batter.

·        If *Slip Mixture becomes too thick for attaching or mending, thin back with slip - not water.  (Adding water will increase shrinkage.)

·        Unused *Slip Mixture may be stored in an airtight sealed container for several days.  Add more slip if it becomes too thick.

·        If *Slip Mixture is left open to air, it will dry and become greenware.

ADD-ONS - ATTACHMENTS - REPAIRS ON

Wet Greenware

1.                 Apply *Slip Mixture to pieces that will be attached.

2.                 Gently and firmly press pieces together (no scoring necessary).  Bonding occurs immediately.  Be sure pieces are positioned correctly.  NOTE:  Some pieces may still require propping.

3.                 Clean excess with cleaning tool or damp sponge.  Limit use of water as it causes shrinkage and stress cracks.

4.                 After greenware dries, clean as usual and fire to a greenware firing.

Dry Greenware

1.                 Apply APT-II Porcelain/Stoneware Enhancer - not water directly to broken pieces.

2.                 Immediately, apply *Slip Mixture to broken pieces.

3.                 Position pieces correctly - gently and firmly press pieces together.

4.                 Immediately clean excess with regular cleaning tool or damp sponge.

5.                 Let dry - fire to the recommended greenware firing.

Stress Cracks on Greenware

1.                 Apply APT-II Porcelain/Stoneware Enhancer from bottle into stress crack.

2.                 Immediately fill with *Slip Mixture.

3.                 Clean excess with cleaning tool - let dry as usual.

4.                 Re-fire to a greenware firing.

Bisque Repair

1.                 Thicken slip with APT-II Porcelain/Stoneware Enhancer until it becomes a clay
mixture.

2.                 Shape into a pencil - let dry.

3.                 China Fire pencil to a Cone 018.

4.                 Crush bisque pencil into a powder and make a paste by adding
APT-II Porcelain/Stoneware Enhancer.

5.                 Apply APT-II Enhancer to cracked areas - do not let dry.

6.                 Immediately apply paste mixture into cracked areas.

7.                 Clean excess, let dry and fire to a bisque firing. 

Decorating and Sculpting with Slip

DECORATING TOOLS:  Cake Decorating Tool, Cookie Press Clay Gun, Extruder, Palette Knife, Sponge, Scafitto Tool, etc.  NOTE:  Pipe as usual when decorating - do not stretch because the clay will shrink and crack when drying.

  1. Slip can be thickened from a pouring texture to a modeling clay texture.  Thicken slip with APT-II Porcelain/Enhancer to the consistency required for decorating or sculpting, i.e.

a)     A thick creamy mixture for slip sculpting.

b)     A very thick mixture for build-up applications.

c)     A butter cream to royal icing consistency when using decorating tools.

  1. If slip mixture becomes too thick for your project, thin back with slip - not water.  (Adding water will increase shrinkage of greenware decorations.)

Decorate on Wet Greenware

  • Decorations can be made from slip.  Add APT-II Porcelain/Stoneware Enhancer to thicken the slip to a consistency required.  Decorations will bond immediately to greenware.

  • Slip mixture may be colored with Stokes.  Decorations will fire to the color that is applied.

  • Allow normal drying time before finishing your greenware.

Decorate on Dry Greenware

1.                 Apply APT-II Porcelain/Stoneware Enhancer on the specific area.

2.                 Decorate immediately on the dampen area using slip that is thicken with APT-II Porcelain/Stoneware Enhancer to the desired consistency.

3.                 If decorations are dry, dampen with APT-II Porcelain/Stoneware Enhancer.

4.                 Use a small amount of  *Slip Mixture as an attaching agent to attach decorations to greenware.

5.                 Press gently and firmly into place and remove any excess slip.

6.                 Allow normal drying time before firing. 

Decorate on Fired Glaze Surface (Flat)

1.                 Apply APT-II Porcelain/Stoneware Enhancer on the specific area.

2.                 If decorations are dry, dampen with APT-II Porcelain/Stoneware Enhancer.

3.                 Use a small amount of *Slip Mixture to attach decorations.

4.                 Press gently and firmly into place and remove any excess slip.

5.                 Allow normal drying time before firing to a glaze firing.

NOTE:  If decorating on a movable glaze, you will need to position piece horizontally in kiln to prevent decorations from sliding.

Lace Draping


1.                 Add APT-II Porcelain/Stoneware Enhancer, a few drops at a time into slip, stirring until a creamy consistency occurs.

2.                 Dip cotton lace into slip mixture.  NOTE:  APT-II will allow you to use a cotton/polyester blend.

3.                 Work slip mixture into lace as usual.

4.                 Attach lace with a draping tool.  *Slip Mixture may be used for attaching.

5.                 Spray or brush APT-II Porcelain/Stoneware Enhancer over the laced area for added durability.  This is very important because it eliminates some of the chipping and cracking.

Modeling Clay

APT-II Porcelain/Stoneware Enhancer added to clay has enriched the ability as an artist in ceramics to stretch and pull the clay to its ultimate limit and still retain its high quality of the translucency of porcelain.

It strengthens the extension of the translucent areas in all stages of the clay and allows the freedom to create fine details.

When the clay is in a dried stage, you can add new clay to the dry clay and change the design if desired.

When loading the greenware in kiln, there is less breakage in a Cone 10 firing - especially delicate pieces.
 

1.                 Wedge APT-II Porcelain/Stoneware Enhancer into moist clay.  This will plasticize the clay for more elasticity while you're sculpting. 

2.                 If you work with block clay, punch holes in clay - fill with APT-II Porcelain/Stoneware Enhancer - then wedge. 

3.                 Clay becomes more durable with less shrinking and cracking when hand forming and sculpting.

4.                 The RAKU technique has proven to have a more durable piece when using APT-II Porcelain/Stoneware Enhancer in the clay.

SLIP TO MODELING CLAY

1.                 Thicken slip by adding 1-2 teaspoons of APT-II Porcelain/Stoneware Enhancer per cup of slip.  Mix thoroughly and place in an airtight container (zip-lock bag) for 12-24 hours to age and plasticize.

2.                 Remove from container and place on newsprint or plaster batten to remove excess water from clay.  Pieces made from this mixture will dry like greenware instead of clay.  Very little stress breakage occurs with excellent green strength.
