Grain is the language of wood veneer — and like any language, it has vocabulary worth learning. Figure, burl, and flake are terms designers use casually but often without a precise shared understanding of what causes each pattern and where it performs best. This post is a working glossary and specification guide for reading wood grain with confidence, drawn from what we see across Sparlin’s natural veneer range every day.
What Is “Figure” in Wood Veneer?
Figure is the umbrella term for any distinctive visual pattern in wood grain beyond plain, straight lines — it’s essentially the wood’s natural decoration, caused by irregularities in how the tree grew.
Figure results from factors like grain direction changes, growth stress, disease, injury, or unusual cellular structure within the tree.
Common figure types include cathedral (crown cut arches), fleck/flake (from quarter cutting certain species), burl, and curl/fiddleback patterns.
The more pronounced the figure, the rarer and typically more expensive the veneer, since dramatic figure occurs in a smaller percentage of any given log.
Figure is a major driver of a veneer’s “personality” — two sheets of the same species can look completely different depending on the figure present.
Understanding Burl
Burl is one of the most dramatic and sought-after figure types in the veneer world, and it has a very specific biological origin.
Burl forms when a tree develops an abnormal growth — often triggered by injury, fungal infection, or stress — causing the grain to grow in swirling, contorted patterns instead of straight lines.
Because burl growths are irregular and relatively rare on any given tree, burl veneer commands a premium price and is typically reserved for feature applications.
Ash burl is a specific example commonly used in high-end veneer ranges for its intricate, densely swirled pattern and warm tonal variation.
Burl veneer is almost always used as an accent or focal material — inlay panels, tabletop centres, feature door fronts — rather than as a large-area surface material, both for cost reasons and because its intensity can overwhelm a space if overused.
Understanding Flake and Fleck Figure
Flake (also called fleck or ray fleck) is a distinctive figure type most commonly associated with quarter-cut species like oak.
Flake figure comes from medullary rays — structures that run radially from the centre of the tree outward — which become visible as bright, irregular patches when the log is quarter-cut.
It appears as scattered, silvery or lighter-toned patches across an otherwise straight grain background.
Flake figure is prized in traditional and Arts & Crafts-influenced interior styles, where it reads as a marker of quality quarter-sawn material.
The intensity of flake varies by species and by exactly how close to true quarter the log was cut, giving suppliers some control over how pronounced the effect is.
Other Notable Grain Patterns Worth Knowing
Curl/fiddleback: A rippling, wave-like figure that catches light differently across the sheet, creating a shimmering, almost three-dimensional visual effect.
Ribbon stripe: Common in species like sapeli, where interlocked grain produces alternating light and dark stripes as the sheet is viewed from different angles.
Bird’s eye: Small, swirling eye-like patterns scattered across the grain, most famously associated with certain maple species.
Pommele: A dense, rippling pattern resembling hammered metal, often found in African species and prized for decorative feature work.
How to Read a Veneer Sample for Grain Quality
Look at the sheet under multiple lighting angles — figure like curl and ribbon stripe changes dramatically depending on light direction, and a sample viewed under only one light source can be misleading.
Check for consistency across the sheet — some figure types (like fleck) are naturally scattered, while others (like cathedral) follow a predictable, repeating rhythm.
Assess how the figure will read at installation scale — a striking pattern on a small sample can look busy or, conversely, disappear entirely when scaled up across a full wall.
Consider how the figure interacts with your finish — darker stains can mute subtle figure, while clear or light finishes tend to accentuate it.
Specifying Figure, Burl, and Flake for Different Applications
Statement furniture pieces (boardroom tables, reception desks): Burl or strongly figured crown cut veneer creates an immediate visual anchor and signals craftsmanship.
Large wall paneling: More restrained figure types like straight-grain quarter or rift cut prevent visual fatigue across a large continuous surface.
Inlay and marquetry work: Burl and highly figured veneers are frequently used as accent inlays within a calmer field veneer, concentrating drama into a smaller, intentional area.
Doors and cabinetry fronts: Ribbon stripe or moderate cathedral figure often strikes a good balance between visual interest and everyday livability.
Ceilings and soffits: Subtle figure or flake is often preferred here since strong cathedral patterns viewed overhead can read as visually overwhelming.
Why Grain Vocabulary Matters for Client Conversations
Being able to precisely describe figure, burl, and flake elevates the conversation with clients from “which wood colour do you like” to a genuinely informed design discussion.
Clients often respond emotionally to figure before they understand why — being able to explain that a swirling pattern is burl, caused by natural tree stress, adds a story that increases perceived value.
Precise vocabulary prevents miscommunication when working with contractors and suppliers — asking for “flake figure quarter-cut oak veneer” gets a far more predictable result than asking for “wood with some texture.”
Understanding grain types helps you set realistic expectations with clients about natural variation, reducing disputes when delivered veneer doesn’t look identical to a single sample sheet.

Frequently Asked Questions
Q: What causes burl figure in wood veneer?
A: Burl figure forms when a tree develops an abnormal growth, typically triggered by injury, fungal infection, or environmental stress, causing the wood grain to grow in dense, swirling patterns instead of straight lines. Because these growths are relatively rare, burl veneer is considered a premium, feature-grade material.
Q: What is flake figure and which species commonly shows it?
A: Flake, or ray fleck, figure appears as bright, irregular patches caused by medullary rays becoming visible when a log is quarter-cut, and it’s most commonly associated with species like oak. The intensity of flake varies depending on how close to a true quarter angle the log was sliced.
Q: Is highly figured veneer more expensive than plain grain veneer?
A: Yes, highly figured veneers like burl, curl, and pronounced cathedral figure typically command a premium because these patterns occur in a smaller percentage of any given log and require more careful selection and processing. Plainer, straight-grained veneer is generally more economical due to higher, more consistent yield.
Q: Can burl veneer be used across a large wall area, or only as an accent?
A: While technically possible, burl veneer is most commonly used as an accent or focal feature — such as an inlay panel or a tabletop centre — rather than across large continuous areas, both for cost reasons and because its intensity can visually overwhelm a space at scale. Pairing burl accents with a calmer field veneer typically produces a more balanced result.
Q: How does lighting affect how wood grain figure appears?
A: Figure types like curl, fiddleback, and ribbon stripe are directional and can shift dramatically in appearance depending on the angle and intensity of light hitting the surface, sometimes appearing almost flat under one light source and shimmering under another. Always view veneer samples under multiple lighting conditions, ideally matching your actual project lighting, before finalising a specification.
Q: Why does the same wood species look different on different veneer sheets?
A: Natural veneer preserves the individual grain character of the specific log and even the specific section of that log it was cut from, so variation in colour, figure, and pattern between sheets is normal and expected. This natural variability is part of what distinguishes genuine natural veneer from engineered or printed wood-look surfaces.
