Club Gazes | Ōtaki Pottery Club

Ōtaki Pottery Club Glazes

The club has a variety of glazes available. They are divided into 4 categories:

For simplicity we will categorise glazes with the following codes:

Clear (C)
Opaque (O)

These indicate transparency

Shiny (S)
Satin (Sn)
Matt (M)

These denote surface texture.

Buckets marked (TX) are a mixture of glaze remnants that cannot be repeated.

Abbot’s Clear(C)(S)
An expensive commercial glaze with a wide firing range (1000 – 1240). It can be fired to 1250 but this
is slightly above the recommended range. It can be applied thinly. It does not run. It is excellent over
underglaze colours, stains, Oxides, coloured slip and agate ware. It can be used over all clays. It is
important NOT to contaminate this glaze especially when using over oxides, stains and underglaze
that has not been bisque fired. (Apply by spraying).

Abbots White (O)(S)
An opaque version of Abbot’s Clear. Very stable. Does not run. Fragments colour when applied over
this glaze.

LOW-FIRE GLAZES (Earthenware). 1080-1100 deg.

Best fired over white slip on terracotta or low fire pale clay.

HIGH-FIRE GLAZES (Stoneware cone 8) 1250

Waikato White (O)(S)(Sn) - This is a stable glaze that takes oxides, stains, under glaze and pigments well. It works well over other glazes.
Tin White (O)(Sn)(S) - This is a stable glaze that fragments (speckles) other glazes when dipped, sprayed or poured over them. A fine dusting over oxides will give them a sheen. Over BRT it will draw out the black fleck in the clay. A fine spray over buff clays will produce an orange sheen.
Transmutation (O)(Sn) - A creamy/white glaze that is designed to “pull through” oxide decoration on bisqueware. It can also be used on its own or in combination with other glazes.
Storm Cloud (O)(Sn)(M) - A stable blue/grey glaze good on domestic ware and sculpture. Breaking green/brown where thinly applied.
Tenmoku (O)(S) - A dark black/brown breaking tan on ridges
Satin Black (O)(Sn) - Stable.
Intense Blue (O)(S) - Stable -a strong cobalt/ royal blue.
GD Blue (C)(S) - A clear Victorian blue.
Ian’s Blue (O)(M) - Matt grey/blue breaking green where thin. A sculptural glaze. Can run on vertical surfaces where applied thick. Spraying gives good variation and usually avoids runs. Toxic
Neil Grant Clear (C)(S) - a stable high fire clear glaze.
Neil Grant Green (C)(S) - Stable, Soft Green. Best over pale clays
Jade (C)(S) - moss green.
Irvine’s Chung – Overglaze best over Tenmoku
Smooth Turquoise (O)(Sn)(M) - Toxic (Barium) Use gloves - Not Food safe. Blue breaking green where thin. This glaze is best applied thickly but it RUNS on vertical surfaces; do not apply to the bottom third of the pot. Good for sculptural and decorative work. Takes glass well.
JB Fleck (O)(S) - Rust red with dark fine flecks where thicker. It will run if too thick around the base.
Shaner Oribe (semi-O)(S) - Soft green
Matt White Stoneware (O)(M) - Creamy white.
