Mayco Specialty Glaze SG202 White Cobblestone 473ml

SG-202 Mayco Glaze White Cobblestone 473ml

Cobblestones create a textured “cobbled” surface when fired. Apply over another glaze and during the firing process, a shattered pattern of raised, irregular chips will emerge. The underlying glaze will appear in the cracks. Certified AP® Non-Toxic and Food safe; however not recommended for food surfaces due to surface characteristics.

Size: 118ml

Colour: White

Firing Range: Cone 06 - Cone 6

• Cone 06 oxidation: A white shattered pattern of raised, irregular chips will emerge. The underlying glaze will appear in the cracks.
• Cone 6 oxidation: Glaze will bead up on the surface of the piece. If applied over another glaze the texture flattens with similar cobblestone pattern.
  
  

Product Characteristics:

• For a colourful texture effect, apply 1 coat of Mayco Stroke & Coat (or similar) over Cobblestone glaze.
• Cobblestones may also be fired to cone 6 to add a unique look to mid-range fire designs.
• Great for replicating skin patterns and textures of reptiles and spotted animals.

Application Recommendations:

To achieve the cracked pattern (as pictured) apply Cobblestones over any non-toxic glaze.

While Cobblestones can be applied over a previously fired glaze the cracked pattern will become more pronounced if applied on an unfired glaze.

• Shake for 5-6 seconds or stir thoroughly before use.
• Dispense glaze onto a palette (tile, plate, etc.) and apply 2 coats with a broad, soft brush or sponge.
• Apply the second coat while the first coat is still damp: do not allow Cobblestone to dry between coats.
• Handle carefully as the dried glaze has a tendency to flake.  
• Pattern break-up is determined by the application direction of the brush stroke. Large break up heavier application, small breakup lighter application.
• If application is too light the cobblestone will not break up. Reapplying and touching up will not achieve a break up.
• Fire to shelf cone 06 (999° C) or higher.

Usage Tips:

• Amount of product application will influence the final design.
• Firing temperature, length of fire and number of coats will produce color and surface variations.
• Do not spray apply without proper personal protective equipment. 
• Cone 6 results turn glossy.

Safety Information:

Cobblestone glazes are have been certified as Non-Toxic, safe for use by artists of all ages when used according to manufacturer’s directions. However, they are not recommended for dinnerware due to the durability of the fired glaze. Some glazes, regardless of surface texture or porosity of underlying clay body, will be designated as not suitable for dinnerware as the fired glaze surface is not durable and can be impacted by contact with food or liquids. While it may not be harmful, it is certainly not desirable. Further, these glazes exhibit surface textures such as cracks and crevices. While the glazed surface may pass lead & cadmium leach tests, and therefore legally considered Food Safe, attempts to adequately clean the textured surface may cause the underlying porous ware to absorb water and fail. Recommended for ornamental use only.
