Resins, Gums & Balsams — Field Guide, Part III

Mastic has been prized since Greek and Roman antiquity for chewing, incense, breath fragrance, varnish and medicine. Chios developed a distinctive cultivation and grading tradition that continues today. Its name survives in words connected with chewing, but mastic is chemically a resin, not a water-soluble gum.

Commercial Chios mastic comes from Pistacia lentiscus cultivated and managed for resin. Other Pistacia exudates or products labelled merely ‘mastic gum’ may differ. The raw tears are resinous, brittle and largely water-insoluble.

Growers prepare clean ground beneath the plant, make small repeated bark incisions, and allow clear droplets to fall and harden into tears. The harvest is then washed, dried and painstakingly hand-cleaned and graded by size and purity.

Tears are sold whole or milled; distillation gives a pale essential oil; alcohol can produce tincture or extract. Heat softens the resin and can cause clumping. Food, incense, varnish and fragrance grades may have different specifications.

In perfumery, mastic adds clean Mediterranean green-pine freshness to herbal, incense, citrus and woody accords. Its film and tack properties have specialty uses, but it is not a universal cosmetic resin. Traditional chewing is outside a fragrance formulation guide.

High-grade tears are small, pale yellow, translucent, glassy and brittle, with a fresh green-resin odour. Ground material loses the easiest visual clues. Larger dark pieces contain more impurities or are lower grade.

Confirm Pistacia source, intended grade and allergen profile; people sensitive to related Anacardiaceae materials may require caution. Use the supplier’s current IFRA and cosmetic documentation, not food-use history.

Damar is a Malay trade word for resin and historically also for resin light or torch material. It became a major Southeast Asian varnish, lacquer, incense and local waterproofing resin. Nineteenth- and twentieth-century artists adopted dammar varnish, while synthetic resins later reduced many industrial uses.

Dammar is a family of hard resins, not one species. Indonesian trade distinguishes forms such as pale crystalline mata kucing (‘cat’s eye’) and darker ground-collected batu (‘stone’). Sal dammar from India comes from Shorea robusta and should be named separately.

Some dammar is tapped from living dipterocarp trees; some is gathered from the ground in aged or semi-fossil form. Sumatran damar gardens are a notable agroforestry system in which resin trees grow with other crops. Deep tapping or timber pressure can undermine sustainability.

Raw resin is cleaned and graded, then dissolved for varnish or further refined. Dewaxing removes a high-melting fraction for better compatibility. Only a small portion is distilled or extracted for aromatic use; common artist’s dammar solution is not cosmetic grade.

In this guide dammar matters mainly as an incense material, a visual comparison resin and an occasional fragrance modifier. Its dominant modern roles are varnish, coating and specialty technical applications, not skin benefit or aromatherapy.

Pale dammar is white to yellow, translucent and brittle, often in irregular chunks. Darker ground material is more opaque and contaminated. It is generally harder and less aromatic than fresh elemi and more solvent-soluble than many hard copals.

Trade names cover many species and grades. Require botanical or trade source, contamination limits and intended cosmetic status. Varnish solvents and artist products must never be repurposed for cosmetics or incense.

Copal has separate histories in Mesoamerican ritual incense, African trade and Asian varnish production. European commerce later grouped many hard resins by geography — Congo, Zanzibar, Manila and others — and used vast quantities in varnish before synthetic resins displaced them.

Copal is not a botanical identity. It is a broad trade class spanning fresh resin, semi-fossil material and older buried resin from unrelated trees. Manila copal is commonly associated with Agathis; East African and American copals may come from other genera. Age and source determine solubility and odour.

Living trees may be tapped, while semi-fossil copal is dug from soil below or near former trees. Historic fossil collection and modern plantation tapping create very different supply chains. Source-country legality and forest management must be documented.

Raw copal is cleaned, graded and sometimes heat-treated to improve oil solubility for varnish. For incense or fragrance study it may be powdered or tinctured, but hard copals often extract poorly. Processing history should be declared because heated resin differs from native resin.

Modern aromatic use is chiefly incense, niche natural perfumery and historical reconstruction. Hardness and film properties explain its varnish legacy. A generic ‘copal benefit’ is meaningless because the name covers many chemistries.

Pieces range from pale yellow and glassy to deep amber, weathered or opaque. Hard copal has a relatively high softening point and may be less soluble than dammar. No colour or burn test can identify the botanical source safely.

Never buy on the common name alone. Require country, botanical source where known, age class, collection method and contaminant testing. Burning produces smoke; do not market copal incense as air-purifying or therapeutic.

Sandarac was an important North African and Mediterranean incense and varnish resin. Medieval scribes and craftspeople used related resin preparations, and later European varnish makers valued its pale hard film. Its industrial role declined with newer resins, but it remains recognizable in art materials and incense.

True sandarac comes from Tetraclinis articulata, a small Cupressaceae conifer. It should not be confused with red realgar pigment historically called sandarac in some texts, nor with generic pale copal or mastic.

Resin exudes naturally or after small bark incisions and dries into elongated tears. The pieces are collected, cleaned and graded. Responsible harvest is important in slow-growing dry Mediterranean woodland.

Tears may be powdered or dissolved for varnish; fragrance use is usually as incense, tincture or a rare supplier extract. Artist varnish solutions often contain unsuitable solvents and are never fragrance ingredients.

Sandarac contributes a dry, pale conifer-resin incense effect and is useful in historical scent reconstruction. Its main documented function is film-forming varnish resin, not a modern cosmetic active.

Clean tears are pale yellow, transparent, elongated or pear-shaped, dry and brittle. Mastic tears are usually smaller and rounder; dammar is often chunkier. Natural variability and breakage make these only visual clues.

Verify Tetraclinis source, harvest legality and intended grade. Keep resin dust controlled and do not repurpose art materials. Any fragrance extract still needs current safety documentation and finished-product assessment.

Dragon’s blood was traded across the ancient and medieval worlds as pigment, varnish, incense and medicine. Roman, Arab, Chinese and European sources used the dramatic name for different red materials. This history created a family of trade products rather than one universal resin.

Socotra dragon’s blood comes from Dracaena cinnabari; Canary material from D. draco; East Indian dragon’s blood historically came from resin coating rattan-palm fruits; South American sangre de drago often refers to red Croton latex. These are not interchangeable in chemistry, safety or cosmetic status.

Dracaena resin is collected from trunk exudate after careful incision. Rattan-palm resin is dislodged from dried fruit surfaces, sifted and consolidated. Croton latex is tapped as a liquid. A four-stage recognition image is representative of Dracaena, not every material sold under the name.

Raw red resin may be cleaned, powdered, warmed into sticks or tinctured. Some products are standardized as colour extracts; others are incense resin. A dark red liquid gives no evidence of species without documentation.

Fragrance use is limited and often secondary to colour, incense or historical storytelling. In cosmetics, exact INCI identity and colour-additive legality matter. Traditional wound or medicinal uses must not be generalized across unrelated species or presented as product claims.

Genuine products range from crimson powder and brittle red-brown chunks to dark latex. Source form is diagnostic: fruit-surface resin, tree exudate and latex look different. Artificial dyes and mixed botanical sources are a known risk.

The common name is never enough. Require species, plant part, extraction, geographic origin, contaminants and legal cosmetic status. Conservation-sensitive island species and wild collection require special scrutiny.

The Taíno name entered European languages in the sixteenth century when lignum-vitae wood and resin were promoted as medicines and prized for exceptionally dense timber. Guaiac resin later became a chemical reagent, while perfumery adopted the smoky, rosy odour of guaiacwood oil. These are related products but not the same material.

True Guaiacum species yield resin-rich wood; natural guaiac resin can be extracted from the wood. Steam-distilled guaiacwood oil is a volatile wood product, not simply melted resin. Trade names may also involve Bulnesia or other woods, so botanical and CITES identity must be explicit.

The resin is obtained from resinous heartwood or as a processed extract rather than by collecting tears from a tapped trunk. Because the trees are slow-growing and historically overlogged, wood origin and legal harvest are more important than a romantic ‘wild’ story.

Wood can be chipped and distilled for essential oil; resin is separated by controlled extraction. Rectification and fractionation modify smoky, phenolic and floral facets. A supplier should state whether the product is wood oil, resin, resinoid or a fragrance base.

Guaiacwood oil gives smoky tea, rosy-violet, leather and soft vanilla-wood effects in fine fragrance. Guaiac resin is rarer and historically important. Neither should be presented as a medicinal cosmetic active.

Resin is dark greenish-brown and brittle; dense wood chips show resinous amber areas. The essential oil may be viscous or semi-solid depending on temperature. Colour does not resolve Guaiacum from substitute woods.

International trade in Guaiacum species is controlled under CITES Appendix II. Require species, permit status, chain of custody, extraction, SDS and IFRA documentation. Do not support unidentified or illegally harvested lignum-vitae wood.

Protium resins have long been used by Indigenous and local Amazonian communities as incense, caulking, light, aromatic material and in traditional practices. Breu branco has gained wider contemporary attention in Brazilian perfumery as a distinct local resin rather than a generic substitute for frankincense.

The name can cover more than one pale Protium resin. P. heptaphyllum is a major reference source, but regional botany and vernacular naming vary. Some trade catalogues also use ‘Brazilian frankincense,’ which describes an odour analogy, not Boswellia identity.

Milky exudate forms naturally or after controlled bark injury and dries to pale yellow or off-white lumps. Ground collection may add bark and soil. Responsible harvest uses limited wounds and maintains tree and community traceability.

Clean resin is burned as incense, tinctured or steam-distilled for a pale aromatic oil. Solvent or CO₂ extracts may retain heavier resin notes. The raw resin, distilled oil and tincture differ substantially.

Breu branco contributes sparkling citrus-pine incense and humid forest character to modern natural perfumery. It can bridge top notes and resinous woods. Cosmetic use is fragrance only unless a separate evidence-based function is established for the exact ingredient.

Fresh or dry resin is white to pale cream or lemon-yellow, becoming amber with age. It is more vivid and citrus-like than most dammar. Visual similarity to elemi or pale frankincense requires botanical verification.

Require exact Protium species or defined blend, origin, harvest method, GC profile, SDS and IFRA certificate. Oxidized terpenes and smoke exposure from burning remain safety considerations.

Lac has been cultivated in South Asia for centuries for red dye and protective resin. European trade developed shellac into a major varnish, polish, record and electrical-insulation material before synthetics replaced many uses. Refined shellac remains important in coatings, foods, pharmaceuticals and cosmetics.

Shellac is a natural resin but not a plant exudate: insects form a resinous encrustation on host twigs. The biological origin matters for vegan claims. Sticklac, seedlac, flake shellac, dewaxed and bleached grades have different composition and colour.

Resin-coated twigs are harvested as sticklac. The material is crushed and sieved; washing removes much of the dye and debris to form seedlac. Responsible production manages host trees and insect cycles rather than treating lac as a wild tree sap.

Seedlac is melted and filtered or solvent-refined into flakes or sheets. Dewaxing improves clarity; bleaching lightens colour but changes the product. Cosmetic shellac is supplied as a defined solid or solvent solution with purity and residual-solvent specifications.

In cosmetics shellac is a film former in hair, nail, mascara and specialty long-wear products. It is not primarily a perfume material, though crude lac has a faint resin odour. Finished-product flexibility, adhesion and removal must be tested.

Sticklac coats twigs; seedlac is granular; flake shellac forms thin amber-orange sheets. Bleached grades can be pale. A liquid ‘shellac’ is a solution and must declare its solvent and concentration.

Confirm cosmetic grade, wax content, colour, solvent, allergen information and microbiological or contaminant limits. Shellac is animal-derived for labelling purposes. Industrial wood-finishing shellac is not a cosmetic ingredient.

Amber has travelled along European and Asian trade routes since prehistory as jewellery, amulet and incense. Its warmth and colour later inspired a perfume word. Nineteenth- and twentieth-century perfumery made ‘amber’ a major olfactory family, but usually without fossil amber.

Geological amber is polymerized ancient plant resin. It is not ambergris, which is animal-derived, and not the modern amber accord. Perfumery amber is commonly built from labdanum, benzoin, vanilla-like notes and synthetic amber materials; recipes vary.

Fossil amber is mined from sediment or gathered where deposits erode. This is geological extraction, not renewable tapping. Provenance also matters because reconstructed, pressed and plastic imitations are common in the gem trade.

Heating or destructive distillation can produce a smoky ‘amber oil,’ but this is rare, chemically transformed and not the normal source of an amber perfume. Modern perfumers construct the effect by blending separate materials under normal fragrance safety controls.

This page prevents a common recognition error: a bottle labelled amber fragrance usually means an accord, not liquefied fossil resin. Fossil amber itself belongs mainly to jewellery, collections and historical incense.

Natural fossil amber ranges from pale yellow to red-brown, opaque to transparent, with weathered crusts in rough material. Visual tests do not reliably authenticate it. In the illustrated edition, the plate’s final panel intentionally shows multiple vials to represent a constructed accord.

Do not encourage burning unknown fossil or plastic-like material. A fragrance called amber must be assessed from its actual formula and IFRA documentation, not from the romance of the name.
