A condition produced in certain porcelain, fine earthenware, or glass, in which the glaze or enamel appears to be cracked in all directions, making a sort of reticulated surface; as, Chinese crackle; Bohemian crackle.
1.One of the three sounds rice crispies make when you add milk [ snap and pop are the other two sounds ] 2. When glaze melts, it is a molten liquid covering the piece. As it cools and turns back to a solid, it shrinks. It does not always fit the clay body. Since it is not elastic and flexible; it cracks. When a glaze or colorant of another color is rubbed into the cracks, the cracks are more visable. Sometimes, the oxygen in the kiln is reduced during firing. When the glaze shrinks; black carbon fills the cracks, leaving the cracks visable. Craclke glazes are specially formulated to do this on purpose. see crazing
A more or less controlled crazing of glaze for decorative effect: oxides are sometimes rubbed in to enhance the pattern.
A deliberately induced type of crazing. Sometimes finely ground iron oxide is rubbed in and fused in an additional firing with another thin layer of glaze over the top.
glazed china with a network of fine cracks on the surface
having the surface decorated with a network of fine cracks, as in crackleware; "a crackle glaze"
a network of cracks which sometimes forms on the surface of oil painting, similar to "crazing" in ceramics.
In ceramic glazes, a network of fine craze lines, produced intentionally or accidentally, especially associated with oriental and modern porcelain. Also, in oil painting, when the paint's surface is broken by a network of small cracks.
Decorative craze lines in a glaze.
the intentional creation of a fine network of cracks in the glaze on a clay surface, sometimes darkened for accentuation. Crackle occurs during the cooling process when the clay and the glaze contract at different rates.
Glaze An effect produced by firing pieces at very high temperatures (over firing), appearing as a cracked effect in the glaze. Very similar to, if not the same as, crazing.
Perpendicular disruption; fine cracks appearing in any of the painting’s layers. Crackle Examples
Cracks in the glaze formed intentionally as a decorative feature. (See also - Crazing)
Decorative and intentional fissures netting the surface of a glaze due to a variation in the expansion and contraction of the glaze and the clay body.
In ceramics, and furniture finishing, where the surface is broken or crazed by many fine, irregular lines or cracks. In painting the same effect is known as cracklure.
