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.e floating islands...cool!
