Cobblestone

Application Recommendations

The following application recommendations are based upon the original product development intent and use for the product. 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 before use.
  • Dispense glaze onto a palette (tile, plate, etc.) and apply 2 coats with a broad, soft brush, such as a CB-604 #4 Soft Fan Brush.
  • Apply the second coat while the first coat is still damp: do not allow Cobblestone to dry between coats.
  • 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 or higher.

Usage Variations & FAQs

Application thickness, drying time before firing, firing atmosphere and temperature can all affect the fired results you obtain.

Handle the ware carefully as the dried Cobblestone has a tendency to flake off. Pieces of cobblestone that fall off may be reapplied to the ware using AC-302 Wax Resist If cobblestone flakes off and you reapply cobblestone in that area this area will have a different break up pattern A protective coating of AC-302 Wax Resist can be applied over the cobblestone while the cobblestone is still damp to help alleviate the flaking of the product.

G-202 White Cobblestone can be tinted with One Stroke or Stroke & Coat. Darker pigment colors work best. Always do a test firing. Too much Stroke & Coat color added will lessen the break up pattern SG-202 White Cobblestone can be made into various colors by applying 1 coat of Stroke and Coat on top of the damp cobblestone.(heavy application of S&C can interfere with the break up).

SG-201 Black Cobblestone will not break up over Matte glazes. If Black Cobblestone is desired on Mattes use SG-202 and apply 1 coat of SC-15 to achieve this effect.
