  1. Cracks –One of the major defect found in the Sanitaryware production process. Separation/Split of Sanitaryware surface without breaking apart.
  2. Blisters – Blistering is sharp-edged burst bubble. Can be found in fired ware.
  3. Crazing – Crack in glaze surface area.
  4. Pinhole – Small holes in the ware.
  5. Poor finish – Improperly finished ware at green stage which is found after firing.
  6. Improper/Defective logo – Logo is not properly printed or positioned.
  7. Iron specks –Iron speck found in Glaze surface. Defect can be found after firing.
  8. Stuck – two or more wares stuck together during firing of ware.
  9. Chipping – Small Broken piece from the ware.
  10. Light glaze – less glaze in ware than necessary.
  11. Heavy glaze – More glaze in ware than necessary.
  12. Wavy glaze – Wavy ness of glaze due to improper glaze application.
  13. Crawling – Small portion of the glaze separates from ware leaving the ware exposed.
  14. Leakage – Leak found in ware during water filled and flushed.
  15. Poor repair – Defect due to poor repairing at various stages at process.
  16. Pitting – Small pits in glaze found after firing.
  17. Matte glaze/under fired – Improperly fired or Matte glaze in ware.
  18. Warpage – Bending in ware.
  19. Sulphuring – Dull scum on glaze surface found after firing.
  20. Knocked Glaze – Glaze knocked off during process.
  21. Color fading – Color disappearing after firing.
  22. Bloating – Gas bubble trapped in body during firing.
  23. Blown out – Impurities burns out during firing.
  24. Dunting – Crack formed at silica inversion stage and the glaze filled the crack.
  25. Peeling – Gaze lift away from body.
