Over-grinding of frits can cause hydration and subsequent water release during glaze maturation resulting in blistering. Correction: Reduce ball milling time and coarser grind raw materials in the glaze batch.
An excessive amount of medium used in underglazes, engobes, glazes or overglazes, such as oil, organic gum binders, gum arabic, glue, CMC or Veegum[R] CER, can ferment, causing gas bubbles exiting as blistering in the glaze layer.
DIAGNOSING THE POTENTIAL CAUSES OF GLAZE BLISTERING
MRSA blistering distal dactylitis and review of reported cases.
Blistering distal dactylitis: a case series in children under nine months of age.
Patients with ADDEB may present along a clinical spectrum ranging from localized blistering at sites of frequent trauma to generalized blisters that resolve with atrophic scarring.
RDEB presents with blistering and erosions at birth with positive Nikolsky's sign (extension of blistering or sloughing of epidermis with application of gentle pressure to lesion or perilesional skin) and is associated with scarring, milia, and dystrophic nail beds.
The coating was developed to perform in corrosive environments, commonly found in water storage tanks, where blistering occurs through four mechanisms: osmotic blistering due to substrate surface contamination; osmotic blistering due to water soluble species within the paint film itself; due to cathodic disbondment; and the imposition of a temperature gradient across the paint film.
Blistering can also occur in corrosion cells produced by over-adequate cathodic protection systems.
"Identification of those abnormal genes that permit blistering
will make antenatal diagnosis simpler," says Joseph McGuire of Yale University in New Haven, Conn.
