SG202 White Cobblestone Pint (16 Ounce)
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. To create colored Cobblestones, brush Stroke & Coat glaze of choice over the white Cobblestone and fire.

The following application recommendations are based upon the original product development intent and use for the product. Information on alternative application methods is listed in the section "Usage Variations and FAQ's". To achieve the cracked pattern (pictured above: 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 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
Q: What conditions can influence the performance of Cobblestones?
A: Application thickness, drying time before firing, firing atmosphere and temperature can all affect the fired results you obtain.
Q: Any tips for handling ware with unfired, dried Cobblestones on it?
A: 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.
Q: How can I tint Cobblestones?
A: SG-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).
Q: Are there any application situations I should avoid?
A: 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.
