WHITE CRACKLE GLAZE

 


Here are some examples of the White Crackle Glaze 

 


GLAZE RECIPE:

Frit 3124   40

Gerstley Borate 25

Neph Sye. 25

OM#4   10

Zircopax  3

METHOD:

You can double or quadruple the recipe. Weigh the materials, add water and mix until table cream consistency. Sieve twice. Brush 3 substantial coats on with a hake brush,dry between each coat.( Also try pouring or dipping.)

The 'calligraphic' designs are made by ripping masking tape and applying to bisque before applying the glaze. Carefully remove after glaze application and before firing. Everything unglazed will turn black in the smoke.

Fire to 1800 F. Post-fire in a bucket lined and supported by clean news print. Let cool with the lid on. When cleaning, if the smoke satin is stubborn use Comet, a non-abrasive pad and rinse very well.

MY FIRING SCHEDULE:

As mentioned earlier I used a side-loading electric kiln with a pyrometer. When desired temperature is reached turn off the power.

One hour on low,peeps open.

One hour on Medium, peeps still open.

On high until 1800F peeps closed.

NAKED RAKU with and without GLAZES

Image
  This bowl is Naked Raku without the addition of other glazes. This bowl has Blue Velvet and Apple Red, with the Naked Raku. ' NAKED RAKU' is a technique that uses slip and a 'glaze' to achieve crackle effects on bisqued ware. It's called Naked because the piece is not glazed per se. Just smoked- patterned  bisque. The piece is painted with the slip (recipe to follow) then covered with a 'glaze' (recipe below). It's not rocket science once you get the hang of it so I wanted to see what else I could do.  The slip/glaze was applied to specific areas sometimes in a planned design, then 3 coats of Blue Velvet was applied to all other areas butting right up to the slip. Occasionally I applied Spectrum Apple Red to add more interest. The pieces were fired to 1700F then post-fired as usual, one quick 'burp' then lid on until cool.  Getting the slip off can be tricky but do not submerge in water no matter what you may read elsewhere. Things get gummy a...

COMBINATION GLAZES

Image
This piece is a combination of White Crackle on the outside and Turquoise on the interior. This bowl has Silver Nitrate on the inside and Blue Velvet on the exterior.* This small bowl has Turquoise over White Crackle. This bowl has Silver Nitrate with bands of a Mayco blue, a commercial glaze. This bowl is glazed with Spectrum Apple Red on the interior and Spectrum Green on the exterior. Using combinations of glazes,especially commercial glazes opens your palette to many possibilities. The Apple Red by Spectrum is excellent and often becomes lavender in heavy reduction. As you can see the green glaze peeled off in the most wonderful way creating texture. No need to remind you they are not food safe... *The bowl with the fan design was made like this:  Draw a design on your bisque. I use Mayco White glaze and apply 3 coats on the design then fire to about 1750F. No raku yet. Let cool in the kiln. Paint 3 coats of Blue Velvet over the exterior of the piece and clean off the design ge...

INTEGRATING DESIGNS

Image
This bowl in the  'Byzantine Crackle'  technique was cr eated like this:  On the inside of the  bisqued bowl I drew the dual leaf-frond pattern then applied wax resist carefully to articulate the design. Then 3 coats of White Crackle was applied with a wide hake brush to the entire piece. A small damp sponge cleaned off the waxed pattern if glaze stuck there. It was fired to 1750F and allowed to cool in the kiln.Then with a soft fan brush Blue Velvet was applied over the entire piece and right away you can see the crackles absorbing the glaze. This takes practice not to brush the glaze off the crackles. Be patient. Where the pattern was waxed and burned out, the bowl will have a pure Blue Velvet  glaze. Fire to 1800F and post fire. The design of the flying geese was made like this: First the geese were drawn to a scale that suited the size of the bowl in different flying configurations, then 3 coats of Mayco White glaze was carefully applied with a fine bru...
