Understanding Blue-and-white ceramics
What Blue-and-white ceramics is and how it is made
History
Safavid blue-and-white production is often associated with Kerman and Mashhad, though exact attribution of many pieces is debated. Some carry pseudo-Chinese marks.
Technique
Cobalt pigment is painted onto the unfired stonepaste body and covered with a transparent glaze, fixing the blue beneath the surface in a single firing.
Collecting and identification
Body colour and hardness, cobalt tone and marks help separate Iranian stonepaste from Chinese porcelain; attributions should be treated as provisional.
This guidance is educational only and is not an authentication or valuation service.
General background on the craft, not a statement about any individual object; dates and attributions summarise common positions in the literature and remain under review. Read the full Blue-and-white ceramics entry.
Before you buy: what to inspect
- Look at the unglazed foot ring — it shows the body clay (red earthenware or white stonepaste).
- Hand-painted decoration has slight variation in line weight and colour; transfers look perfectly even.
- Tap gently: a dull sound may indicate a hidden crack or old repair.
- Examine the glaze under raking light for crazing, chips and retouching.
Typical materials: frit-body.
Red flags: copies and 'Persian style' imports
- Decal or transfer printing sold as hand-painted.
- Artificial ageing (dirt rubbed into new pieces sold as antique).
- Antique claims with no provenance.
A genuine Blue-and-white ceramics piece should come with a named place of making in Iran (often kerman, mashhad) and a clear statement that it is handmade.
Questions to ask the seller
- Is the decoration hand-painted?
- Is the glaze food-safe (lead-free)?
- Has the piece been restored?

Care and cleaning
- Treat decorative and older pieces as display-only unless the maker confirms food safety.
- Wash by hand in lukewarm water with mild soap; avoid dishwashers.
- Avoid sudden temperature changes, which cause cracking.
Storage
- Store with soft padding between pieces.
- Keep away from shelf edges and vibration.
Shipping
Ask for double-boxing with padding; fragile pieces are best insured.
