Glazed Tile Restoration — Persian & Mughal Heritage

Conservation of glazed tile work on Pakistani heritage monuments. Persian blue, turquoise, white-ground floral patterns associated with Wazir Khan Mosque + similar Mughal-era monuments.

What Is Glazed Tile Work?

Glazed tile work (often called Kashi Kari in Pakistan when locally produced) is a heritage decorative technique using fired ceramic tiles with vitreous color glazes — particularly the iconic cobalt blue, turquoise, white-ground floral patterns. Originating in Persia (Iran), it reached its Pakistani peak under Mughal patronage at:

Wazir Khan Mosque, Lahore — most extensive surviving glazed tile work in the subcontinent (1634)
Lahore Fort, Picture Wall — large mural panels of tile + fresco hybrid
Shahi Hammam, Lahore — interior fresco + tile combination
Bibi Pak Daman, Lahore — shrine tile decoration
Sufi shrines across Punjab — Multan, Uch Sharif famous for tile mausoleums

Why Glazed Tiles Deteriorate

Glaze crazing — fine cracks from age + thermal cycling
Soluble salt damage — sub-florescence pushes glaze off tile body
Mortar failure — lime mortar bedding cracks/spalls, tiles detach
Improper past repairs — cement-based repairs trap moisture, accelerate damage
Water ingress — failed roof/wall waterproofing
Vandalism + theft — historic glazed tiles command high market value

Conservation Approach — ICOMOS Aligned

Sunshine's glazed tile conservation follows internationally recognized ICOMOS principles + Pakistan Department of Archaeology methodology:

Documentation — photographic survey, pattern mapping, tile-by-tile condition assessment
Salt analysis — laboratory testing for soluble salt content
Gentle cleaning — no acid, no pressure washing. Soft brush + distilled water poultices
Consolidation — re-attaching loose tiles with reversible adhesives
Repointing — lime mortar (not cement) for joints
Selective replacement — replicate missing tiles in matching glaze, distinguishable on close inspection (ICOMOS authenticity principle)
Long-term monitoring — annual check-ups + maintenance plans

The ICOMOS Rule: Don't make new work appear identical to original. Use compatible materials + similar craftsmanship, but allow scholars to distinguish original vs restoration from close inspection.

FAQs

Can missing glazed tiles be replicated?

Yes — by traditional kiln workshops in Multan + Lahore that still produce similar glazes. Documentation establishes original colors/patterns, then trained artisans produce replacements. Each replacement marked subtly per ICOMOS authenticity rules.

What's the cost range?

Highly variable. Small shrine: Rs 5-15 Lac. Major Mughal-era monument: Rs 5-25 Crore over multi-year program. Government heritage budgets typically structured as multi-phase tender programs.

Who funds glazed tile conservation?

Department of Archaeology Punjab, Punjab Tourism, Walled City Lahore Authority (WCLA), Aga Khan Trust for Culture (AKTC). UNESCO funding for World Heritage Sites.
