Pewter wire filigree stringing involves embedding ductile lead-free tin alloy ribbons (0.4 mm to 0.8 mm wide) into hairline chisel kerfs surrounding geometric nacre tiles. Serving as both metallic framing and expansion dampers, the ribbons are tapped into glue-primed slots. The completed panel is then levelled with steel card scrapers and hand-buffed with virgin olive oil, bleached shellac, and pulverized sandalwood powder for a durable, fragrant satin finish.

The Architectural Role of Metallic Stringing in Damascene Intarsia
When observing a masterwork of Syrian Damascene intarsia, the eye is immediately drawn to the shimmering silver borders that trace every geometric star and floral tendril. This is not surface painting or glued foil; it is solid pewter wire (Khayt al-Qasdeer) driven deeply into the walnut substrate. Metallurgically, pewter—an alloy of tin, antimony, and copper—is soft and ductile enough to conform to tight arabesque radii without snapping, yet hard enough to withstand aggressive surface scraping.
Functionally, the metal stringing serves as a crucial mechanical buffer. Wood expands and contracts cyclically in response to atmospheric humidity, whereas mineral mother-of-pearl is dimensionally inert. The soft pewter wire acts as a permanent expansion joint between timber and shell, compressing during timber swelling and expanding when wood contracts, preventing the nacre tiles from buckling or shattering.
Drawing, Flattening, and Kerf Insetting Technique
In traditional Damascus souks, wire begins as cast pewter ingots. The artisan pulls round wire through hardened steel drawplates to reduce its diameter, followed by passing it through miniature rolling mills to convert it into a flat, rectangular ribbon roughly 0.5 mm wide by 3.0 mm deep. The bottom edge of the ribbon is slightly barbed with a serrated knife blade to create mechanical teeth.
To install the wire, the craftsman uses a curved Damascus scribing knife (sikkina) rocked back and forth along the wood boundary to produce a continuous slit kerf 2.5 mm deep without removing any wood waste. Hot hide glue is painted into the slit, the pewter ribbon is guided into the channel, and a polished horn hammer or brass mallet taps the ribbon securely to the bottom of the kerf.
The Master Art of Dry Scraping: Taming Three Diverse Materials
Leveling a composite panel containing dense walnut wood, rock-hard calcium carbonate nacre, and malleable pewter wire represents one of woodworking's greatest technical hurdles. Using sandpaper on such a surface is catastrophic: the soft wood and ductile metal sand away much faster than the hard shell, causing dishing, hollows, and metal dust smeared indelibly into walnut pores.
Damascene masters level the panel strictly with heavy steel cabinet scrapers (makhadha) ground with a razor-sharp 45° burr. Held in both hands with thumbs flexing the blade slightly convex, the scraper shears across wood, metal, and shell simultaneously. Because a scraper cuts cleanly rather than abrading, it yields microscopically flat surfaces with crisp boundaries and zero smearing of metallic grey dust into adjacent timber cells.
The Sandalwood and Olive Oil Aromatic Buffing Ritual
Once the surface is scraped dead flat, it is burnished with dry horsetail rush (Equisetum) or 0000 steel wool lubricated with cold-pressed virgin olive oil. Olive oil penetrates deeply into the dry walnut, reviving its dark mocha grain and contrasting dramatically with the icy white pearl.
The signature olfactory hallmark of authentic Syrian furniture is its finishing polish. Master woodworkers blend melted virgin beeswax with clarified bleached shellac, cold-pressed olive oil, and pulverized East Indian sandalwood powder (Santalum album). Applied warm with coarse wool pads and buffed with vigorous friction, the wax fills micro-pores and seals the assembly with a silky, tactile sheen that releases a soothing sandalwood fragrance whenever touched or warmed by room ambient air.
Finishing Regimes for Syrian Damascene Intarsia
Use this reference table to calculate exact physical dimensions, ratios, and specifications before purchasing:
| Finishing Medium | Optical Quality | Tactile Feel | Reversibility & Maintenance | Suitability for Damascene Inlay |
|---|---|---|---|---|
| Olive Oil & Sandalwood Beeswax | Deep, warm, low-sheen organic satin luster | Silky, tactile, natural wood warmth | 100% renewable with fresh annual wax buffing | Master Standard; authentic historical method |
| Hand-Rubbed Bleached Shellac (French Polish) | High gloss mirror clarity; accentuates nacre fire | Glass-smooth, hard, non-greasy finish | Easily touched up with alcohol pad buffing | Traditional; ideal for luxury mirrors and chests |
| Polyurethane / Acrylic Synthetic Varnish | Plastic synthetic shine; clouds natural iridescence | Cold, synthetic plastic feel | Irreversible; requires toxic chemical stripping | Unacceptable; ruins value and historical integrity |
| Tung Oil / Danish Hardwax Oil | Pleasant amber glow; good water repellency | Smooth natural satin sheen | Difficult to reverse; can yellow pale camel bone | Moderate; acceptable for modern hybrid pieces |
Practical Constraints
Every successful decoration project must account for physical and environmental constraints:
Wire Buckling Under Aggressive Hammering
Thin pewter ribbon folds over or crumples instead of penetrating the wood kerf Mitigation: Hold wire taut with flat needle pliers and tap directly perpendicular to the ribbon edge with light, controlled blows
Scraper Blade Dulling from Marine Aragonite
The hard mother-of-pearl facets turn the fine turned burr on steel scrapers after several passes Mitigation: Keep a hardened burnisher rod at the workbench and re-turn the scraper hook every 3–5 minutes
Execution Blueprint & Craftsmanship Sequence
Execute this professional sequence to achieve flawless results without backtracking:
Pewter Ribbon Drawing and Thickness Calibration
Pull 92% tin pewter wire through steel drawplates, then roll into a flat ribbon measuring 0.5 mm × 3.0 mm. Serrate lower edge with a file to form locking barbs.
Knife Kerf Slicing Along Inlay Perimeters
Rock a curved Syrian marking knife along the joint between seated nacre tiles and walnut matrix, slicing a 2.5 mm deep kerf without cutting into tile edges.
Kerf Priming with Liquid Hide Glue
Brush warm liquid hide glue along the open knife kerf to act as both a lubricant during wire entry and a permanent anchoring adhesive.
Wire Insetting and Mallet Tapping
Guide the pewter ribbon into the slit with tweezers. Seat the wire firmly into the floor of the kerf using rhythmic taps from a polished brass hammer.
Wire Trimming and Miter Jointing
Snip wire ends flush with sharp end-cutting nippers. Scribe and overlap intersecting wire junctions at 45° miters to ensure continuous metallic framing.
Initial Rough Scraping with Heavy Card Scraper
Burnish a 45° burr on a 0.8 mm high-carbon steel card scraper. Push diagonally across the panel to plane proud wire and shell flush with surrounding walnut.
Fine Wet Honing and Olive Oil Conditioning
Hone the scraped surface with a 1000-grit water slip stone lubricated with cold-pressed olive oil, clearing away any micro-scratches from the scraper burr.
Aromatic Sandalwood Wax Buffing
Melt pure beeswax, shellac flakes, and finely pulverized sandalwood powder together. Apply warm with wool cloth, buffing vigorously to achieve a shimmering satin finish.
Common Mistakes & Countermeasures
Avoid these costly errors that compromise aesthetics, ergonomics, and budget:
Sanding the panel with coarse rotary or orbital sandpaper
Using pure lead or high-lead wire alloys for stringing
Applying polyurethane or epoxy topcoats over nacre

Frequently Asked Questions
Can brass or silver wire be used instead of pewter?
Yes, brass and sterling silver ribbons are sometimes used in high-end Damascene ceremonial pieces. However, brass and silver are significantly harder than pewter, requiring much greater mallet force to seat and making subsequent hand-scraping substantially more strenuous.
How do you prevent metal filings from discoloring the surrounding walnut?
By using scraping irons instead of abrasives. A sharp scraper produces continuous curly metal ribbons and fine wood shavings rather than airborne microscopic powder, preventing metal particles from lodging in open timber pores.
How often should sandalwood beeswax polish be reapplied to Damascene furniture?
In standard home environments, a thin application of natural beeswax buffed with a flannel cloth once a year is sufficient to protect the timber, nourish the shell facets, and revive the delicate sandalwood scent.
What gives Syrian Damascene furniture its distinctive sweet antique aroma?
The signature scent comes from a combination of aged Mediterranean walnut heartwood, natural pine resin inside hide glue formulations, and the final buffing compound infused with natural pulverized sandalwood and beeswax.
