Damascene Ajami (also known as 'Damas Rooms' or 'Qa'a' interior paneling) is an elite Syrian decorative woodworking craft perfected between the 17th and 19th centuries in the grand courtyards of Ottoman Damascus. Installed across reception salon walls, ceilings, and window shutters, Ajami features relief gesso paste (anba) piped through horsehair quills over seasoned poplar wood, gilded with hammered tin and silver leaf, glazed with luminous colored copal and sandarac varnishes, and highlighted with inlaid mother-of-pearl.
At a Glance: Key Takeaways
- Architectural Setting: The opulent reception salons (qa'a) and winter rooms of Old Damascus courtyard mansions.
- Primary Substrate: Seasoned indigenous Syrian poplar wood (Populus euphratica / Populus alba).
- Relief Gesso (Al-Anba): Pulverized gypsum, zinc oxide, and natural plant gum (tragacanth/arabic) piped in high relief.
- Gilding Technology: Hand-hammered tin leaf (waraq qazdir) and pure silver leaf glued over animal hide size.
- Transparent Glazing: Colored natural copal and sandarac tree resin varnishes tinted with organic madder and saffron.
- Ornamental Motifs: Baroque floral vases, Ottoman carnations, Kufic poetry cartouches, and architectural miradors.

The Damascene Qa'a: Scent, Light, and Palatial Prestige
In the historic courtyard mansions (bayts) of Old Damascus—such as Bayt Nizam and Bayt Sibai—the most prestigious architectural space was the qa'a (reception hall). Designed to welcome high dignitaries, the room was a total work of art where marble fountains played beneath soaring ceilings and walls clad entirely in painted and gilded woodwork known as Ajami.
The term Ajami (traditionally meaning 'foreign' or 'Persian-influenced') designated a luxury multi-media technique combining woodcarving, raised relief gesso, metal gilding, and translucent lacquer-like oil glazes. Under the flickering light of brass oil lamps, the embossed metallic surfaces glowed with hypnotic golden, emerald, and ruby radiance, reflecting the wealth and poetic sophistication of the Damascene merchant elite.
Al-Anba Relief Chemistry and Piping Techniques
The signature three-dimensional feature of Ajami is its raised ornamentation, executed in a specialized relief paste called al-anba. Craftsmen mix pulverized alabastrine gypsum with zinc white (or lead carbonate), fine chalk, and natural water-soluble plant gums—primarily gum tragacanth (katira) or gum arabic.
The paste is loaded into an animal bladder or parchment cone fitted with a hollow reed or brass nozzle. The master artist pipes raised borders, floral petals, and calligraphic inscriptions onto the primed poplar boards like royal pastry icing. Because gum tragacanth possesses high thixotropy, the piped lines hold crisp, steep-sided 3mm-to-5mm profiles without slumping or cracking as they dry.
Tin-Leaf Gilding (Waraq Qazdir) and Tinted Copal Glazes
True gold leaf was extraordinarily costly for hundreds of square meters of wall surface. Damascene masters developed an ingenious optical alternative: tin leaf gilding (waraq qazdir). Paper-thin sheets of hammered tin or silver were laid over the raised relief using garlic juice or animal hide size.
Once burnished, the silver-colored metal leaf was coated with tinted natural resin varnishes (formulated from Zanzibar copal, sandarac, or amber dissolved in linseed oil). Tinted with saffron or gamboge, the clear yellow varnish transformed cheap silvery tin into brilliant, radiant imperial gold! Blue glazes were tinted with indigo, while ruby reds used alizarin madder, creating a rich jewel-toned luster that was waterproof and dust-resistant.
Material Layers of Historic Syrian Damascene Ajami Paneling
Use this reference table to calculate exact physical dimensions, ratios, and specifications before purchasing:
| Layer | Traditional Material | Chemical / Botanical Nature | Visual Function | Conservation Risk |
|---|---|---|---|---|
| Substrate | Syrian White Poplar (Populus alba) | Soft, straight-grained light wood | Structural backing paneling | Wood-boring beetle infestation |
| Ground | Gesso sottile (gypsum & hide glue) | Fine calcium sulfate dihydrate | Smooth, non-porous working base | Water dissolution; delamination |
| Relief (Anba) | Gypsum, zinc oxide & gum tragacanth | Thixotropic plant gum paste | Piped 3D floral & calligraphic relief | Brittle fracture under impact |
| Metal Leaf | Beaten tin leaf (waraq qazdir) | Elemental metallic tin (Sn) / silver | Reflective metallic mirror base | Tin pest (allotropic breakdown below 13°C) |
| Tinted Glaze | Copal/sandarac varnish + saffron/madder | Natural tree resin in drying oil | Transmutes silver leaf to radiant gold | Darkening from candle soot & UV yellowing |
Practical Constraints
Every successful decoration project must account for physical and environmental constraints:
War damage, displaced heritage, and looting of historic Damascene courtyard interiors
Mitigation: Partner with UNESCO and international museum databases (e.g. Damascus Room in MET) to document provenance and restore salvaged rooms.
Execution Blueprint & Craftsmanship Sequence
Execute this professional sequence to achieve flawless results without backtracking:
Season and Tongue-and-Groove Syrian Poplar Planks
Plane dry knot-free poplar boards to 18mm thickness, milling loose-tongue joints to accommodate seasonal movement.
Apply Multi-Coat Gesso Smoothing Ground
Brush three coats of warm rabbit-skin glue and gypsum ground across wood face; sand glass-smooth with horsetail reeds.
Pipe Al-Anba Relief Designs via Parchment Cones
Load gum tragacanth-gypsum paste into nozzle cone; pipe floral arabesques and calligraphic borders in 4mm high relief.
Apply Garlic Size and Water-Gild with Tin Leaf
Paint relief with tacky garlic-juice size; lay hammered tin or silver leaf, pressing tight with cotton wool.
Glaze with Saffron-Tinted Copal Varnish
Brush warm golden-yellow copal varnish over tin leaf, chemically transforming silver reflection into glowing gold.
Inlay Iridescent Syrian Mother-of-Pearl Accents
Chisel shallow recesses into focal floral rosettes and bed hand-cut freshwater mother-of-pearl shells into black mastic.
Common Mistakes & Countermeasures
Avoid these costly errors that compromise aesthetics, ergonomics, and budget:
Repainting historic Damascene Ajami with modern synthetic gold acrylic paint
Using modern chemical paint strippers to clean dirty Ajami panels

Frequently Asked Questions
Why did Damascene craftsmen use garlic juice as gilding size?
Crushed natural garlic juice contains sticky allicin and sulfur compounds that dry to an ultra-thin, aggressively tacky film that does not dissolve relief gesso and provides phenomenal long-term adhesion for paper-thin metal leaf.
What is 'tin pest' and how does it threaten antique Ajami?
Tin pest is an allotropic phase transformation where white beta-tin transforms into crumbly grey alpha-tin when temperatures drop below 13.2°C. Historic Ajami rooms installed in unheated Western museums must be climate-controlled above 18°C.
