About
ARTIST STATEMENT

Porcelain is the foundation of my work, combined wire elements to create a quiet and contemplative charged space.  My current artworks evoke childhood memories and repetitive daily activities involving knowledge and contemplation.  I commit to the same activity to visualize different parts of myself.

I am passionate about duplicating forms using mold making and slip casting technique. This process reveals my fascination with clay replication with subtle variations.  Constant permutation is the core of my creative process.

TECHNICAL STATEMENT

The cyanotype process gives a continuous-tone image of Prussian blue using a sensitizing solution of ferric ammonium citrate and potassium ferricyannide.  When exposed to natural or artificial ultraviolet light, the iron salts are reduced to their ferrous state.  Follow oxidation by immersion the ceramic object into running water, a blue image is formed.

The process

Solution A:  20 gram ferric ammonium citrate/100 ml of distilled water
Solution B:   9 gram potassium ferricyanide/100 ml of distilled water
Store solution separated in brown glass bottle, away from light.  Before use, mix equal parts of Solution A+Solution B as required.  The solutions will have a shelf life of 8 to 24 hours after mixing A+B together.

I mage Transferring

It is advisable to test and to find a clay body to suit your ideas.  I use the following porcelain clay body and slip for the Cyanotype Printing Process.
Clay Bodies and Slip

Porcelain Clay Body     Cone 9-10, translucent

Grolleg Kaolin                 50
Kona F-4 Feldspar        30
Flint                                      20
Macaloid                             3
Water                                  35 lbs per 100 lbs

Blunge the macaloid in 30-35 lbs of water before adding other materials

Reeves Casting Slip      Cone 6-9, translucent


Grolleg Kaolin                 40
Kona F-4 Feldspar        35
Flint                                      25
water                                    30
Darvan 7                            175 gram per 100 l
bs
Mix Darvan 7 with 30 lbs of water before adding other materials.   Release from the mold very fast, but prone to slump

Class Casting Slip          Cone 9-10, translucent

Grolleg Kaolin                 55 (one bag=55lbs)
Cluster Feldspar             20
Pyrax                                    13
Flint                                      12
Water                                   6 Gallon
Darvan 7                             3 oz per 100 lbs
Mix Darvan 7 with water before adding other materials  
Want to make the slip more translucent, omit the Pyrax and increase flint to 20 and the Feldspar to 30 and the clay to 50


Geisman Casting Slip   Cone 6-10, off white
EPK                                       27
OM4 Ball Clay                 27    
Cluster Feldspar             27
Flint                                       19
Water                                   35
Sodium Silicate               181.4 grams per 100 lbs

Dilute sodium silicate with hot water before adding other materials.  May substitute sodium silicate with Darvan 7.  Use 350grams of Darvan 7 per 100 pounds   
Good for hand building and incredible flashing in wood or soda kiln.


Calculating How Much Plaster You Need (from Mold Making & Slip Casting by Andrew Martin)

1 quart of water to 3 pounds of pottery plaster will result in 80 cubic inches of plaster when set.

Calculate the volume:
     Rectangle:  lengthx width x height
     10x15x3=450/80=5.5 quarts of water (round this out to 6) and 18 lbs of plaster

     Cylinder:  pi(3.14) x radius squared x height
     3.14x5x5x6=471/80=5.9 quarts of water  and 18 lbs of plaster
