Introduction
Gongbi flower-and-bird painting is one of the most exquisite traditions in Chinese art, characterized by meticulous brushwork, precise outlines, and layered color application. Beyond the fundamental techniques of line drawing and color washing, accomplished gongbi artists have developed numerous special techniques to create extraordinary textural effects — from tree bark to moss-covered stones, from shimmering water surfaces to weathered leaves. This guide presents thirteen such special techniques, with detailed step-by-step instructions.
Technique 1: Dry Paste Painting Method
The dry paste method uses diluted paste mixed with pigments applied directly onto sized xuan paper, producing saturated colors and rich layering comparable to oil painting. This technique requires a slightly thicker xuan paper capable of withstanding repeated scraping and heavy pigment loads.
Process: Dilute commercial paste with a small amount of water to create a thin consistency. Mix the diluted paste with your desired pigments, then use an oil painting knife to apply and shape the paste-pigment mixture directly onto the paper. While scraping, use the knife tip to carve grass-like textures into the wet paste. For depth, apply transparent plant-based pigments first, then overlay with mineral pigments or gouache — the different pigment properties create visual richness within what would otherwise be a uniform color field. Maintain consistent paste thickness throughout; uneven application will cause the paper surface to warp when dry.
Technique 2: Wet Paste Painting Method
The wet paste method involves brushing a layer of diluted paste-pigment mixture over a dampened sheet of paper adhered to a glass plate, then selectively scraping away areas to reveal the white paper beneath. This technique excels at depicting misty, atmospheric scenes.
Process: Dampen a glass plate and smooth a sheet of thick sized xuan paper onto it using a spray bottle to eliminate air bubbles. Mix paste with four to five parts water, add pigment, and brush evenly across the paper surface. The critical variable is paste consistency: too thin, and pigment will flow back into scraped areas; too thick, and the surface will crack and warp when dry. While the paste mixture is still wet, scrape inward from both sides of tree or branch shapes using a painting knife — the scraped areas reveal white paper, instantly forming the image. After scraping, allow the work to dry to about 70-80% before carefully peeling it from the glass; never leave it to dry completely on the glass, as it may adhere permanently.
Technique 3: Reverse Paste Method
The reverse paste method uses a paste-alum mixture as a resist agent applied to the back of raw xuan paper. When pigment and ink are brushed onto the reverse side, they penetrate through to the front only in areas not covered by the resist, creating dramatic black-and-white textural effects.
Process: Mix paste and alum water at a 1:1 ratio. Using an oil painting knife, apply this mixture to the back of raw xuan paper, following the desired image structure. Allow the resist to dry completely, then flip the paper and brush concentrated ink and color onto the reverse side. The resist blocks penetration where applied, so the image emerges on the front with sharp contrast. The key is finding the right paste-alum consistency — too thin and it won't hold; too thick and it will crust, creating unwanted wrinkles.
Technique 4: Water Accumulation and Color Deposition
Master Chen Zhifo, a 20th-century gongbi master, pioneered the ingenious use of sized xuan paper's non-absorbent properties to create controlled color pooling effects. By exploiting the paper's tendency to become slightly uneven when wet, he directed pigment to flow and settle into depressions, producing naturalistic water-mark textures.
Wrinkle-Paper Color Deposition: Fold and crumple a sheet of thick sized xuan paper, then gently unfold it. Brush concentrated pigment and ink across the crumpled surface — the color will naturally pool in the folds and wrinkles. Allow to dry completely without moving the paper, then flip it over, spray with water to relax the fibers, cover with newspaper, and iron flat. The resulting texture resembles natural stone or weathered surfaces.
Technique 5: Water-Drop and Salt Color Deposition
This technique builds on the color deposition method by introducing water drops and salt crystals onto wet pigment surfaces. The water pushes pigment outward, creating pale flow patterns, while dissolving salt crystals aggressively displace pigment, forming moss-like textural clusters.
Process: Apply pigment to sized xuan paper with moderate water content — enough to remain mobile but not so much that it pools uncontrollably. Use a clean brush to drip water onto the upper portion, letting it flow naturally through the pigment. On the lower portion, sprinkle salt crystals. Timing is crucial: the salt must be applied when the pigment is neither fully wet (salt dissolves instantly) nor completely dry (salt cannot displace set pigment). The ideal moment is when the surface sheen just begins to fade. Allow to air-dry without disturbance; do not use a hair dryer, as rapid drying prevents texture formation. When fully dry, brush away residual salt.
Technique 6: Water-Drop and Glue Color Deposition
Similar to the salt method, but using diluted office glue instead of salt. While water drops create flowing white patches with soft edges, glue drops produce smaller, more controlled pale spots with distinctive water-mark edges — ideal for simulating natural leaf spotting or weathered surfaces.
Process: Apply pigment to paper with generous water content. Drop diluted glue solution onto the wet pigment — the glue's viscosity creates a different diffusion pattern than plain water, forming spots with soft halos at the edges. The technique is particularly effective for depicting leaf variegation, weathered bark, or dappled light effects.
Technique 7: Sanding and Washing Method
Because sized xuan paper's alum coating prevents pigment from penetrating into the fibers, applied color sits on the surface where it can be physically removed through washing or sanding. This creates opportunities for adjusting and unifying a composition.
Water Washing: Once a painting is completely dry, use a stiff oil painting brush dipped in clean water to gently wash selected areas. The water loosens surface pigment, which can then be lifted with absorbent paper, revealing lighter tones beneath. This technique can create highlights, soften edges, or correct overly dark passages. Work gently — repeated scrubbing will damage the paper surface.
Sandpaper Method: Using ultra-fine (grade 000) sandpaper, lightly sand raised areas of thick xuan paper that has been previously crumpled and flattened. The sanding removes pigment from the peaks of the textured surface while leaving it in the valleys, creating a dimensional, weathered effect. Sand with extreme care — too much pressure will tear through the paper.
Technique 8: Comprehensive Example — Moonlit Lotus Pond
This example demonstrates the integration of color deposition, layered washing, and atmospheric treatment to create a moonlit lotus pond scene. Begin with pale ink and earth-yellow wash applied across the composition. Build depth through successive washes of darker ink, concentrating color at the edges to frame the central area where moonlight reflects on water. Apply pale mineral green to lotus stems for a touch of vitality. The final stage involves careful adjustment — unifying the atmosphere, harmonizing color relationships, and painting reflections at the water-stem interface to deepen the nocturnal mood.
Technique 9: Willow Catkins and Flying Flowers
This composition combines color deposition and glue-drop techniques. Apply pale earth-yellow pigment for willow branches and leaves, then drop vermilion and mineral blue-green onto the wet surface. As the colors flow and mingle, they create organic, unpredictable patterns. When the surface is about 60-70% dry, drip diluted glue onto selected areas — the glue slowly pushes pigment aside, forming pale spots that suggest drifting willow catkins. Outline only essential structural elements with a fine brush, preserving the spontaneous textural effects wherever possible. For the background, apply water-laden ink around the subject shapes, then drop mica-blue pigment into the wet ink — mica's luminous properties create a subtle shimmer suggesting moonlight on water.
Technique 10: Silent Autumn Waters
This example employs glass-plate water printing and physical object rubbing techniques. First create water-mark textures using the glass plate method on semi-sized paper. Then prepare a printing plate by cutting thick kraft paper to size and building up a withered lotus design using crumpled newspaper fixed with white glue. Sprinkle fine sand onto the glue lines and allow to dry before brushing away excess. Apply pigment to the plate, lay the painting paper over it, and press firmly — the textured plate transfers pigment to the paper. Once the rubbing is complete, use a fine brush to outline the transferred shapes, respecting the spontaneous light-spot patterns. Wash and layer pigment to build depth, leaving the naturally occurring light spots untouched.
Technique 11: Banna Charm — Paste Pressing Method
This technique uses paste mixed with pigment to create bark-like textures through glass-plate pressing. Mix paste and pigment to a consistency similar to tube watercolor — thick enough to hold form but fluid enough to respond to pressure. Apply the mixture directly onto sized xuan paper in the desired tree-trunk shapes. While still wet, press a glass plate firmly onto the painting. The paste mixture adheres to the glass in some areas and remains on the paper in others. When the glass is peeled away after a brief setting period, the resulting pattern mimics the rugged texture of tropical tree bark. The timing of the peel is critical — too soon and the paste won't separate cleanly; too late and the paper may stick permanently to the glass.
Technique 12: Mastering the Complete Workflow
The twelve techniques described above are not meant to be used in isolation. The most accomplished gongbi paintings typically integrate multiple special techniques within a single composition — deposition for background atmosphere, paste methods for textural elements, sanding and washing for highlights and corrections. The artist's skill lies in knowing which technique to deploy where, and in maintaining overall harmony while allowing each method's unique character to contribute to the whole. As with all traditional Chinese painting, the ultimate goal is not technical display but the creation of a living, breathing world — one where technique serves vision rather than calling attention to itself.
Conclusion
These thirteen special techniques represent generations of experimentation and refinement by China's gongbi masters. While they require patience and practice to master, they open up extraordinary possibilities for textural expression within the disciplined framework of fine-brush painting. The key principles across all these methods are: understand your materials deeply, control water content precisely, respect drying times, and always let the natural behavior of pigment, water, and paper contribute to — rather than fight against — your artistic intention.
