Fishscaling
Fishscaling is an enameling defect, which is characterized by small enamel particles chipping off.
Chipping off may happen directly after firing when cooling down or sometimes even days later.
Effected products may usually not be repaired. Due to this reason, this defect is still one of the most described topics within the international enameling industry.
Possible causes of fishscaling
Fishscaling is caused by an unfortunate combination of :
– steel thickness & quality
– enamel frit formula
– enameling process
– firing conditions
– ambient conditions
