Teacher Facilitation Guide: Subtractive Methodologies
Lesson 01
EXPERIMENTAL MATERIALITY
Objectives
Define light through physical removal of pigment.
Manipulate solvent interaction with charcoal/ink layers.
Identify "emergence" as a conceptual strategy.
Material Lab
• Heavyweight hot-press paper (300gsm+)
• Willow charcoal & compressed charcoal
• India ink (waterproof and non-waterproof)
• Isopropyl alcohol (91%) & Acetone
• Steel wool, sandpaper, X-Acto blades
• Kneaded erasers, electric erasers
Facilitation Protocol
01 The Primordial Ground (30 mins)
Students must completely obliterate the white of the substrate. Encourage the use of powdered charcoal or washes of ink. The goal is a "total vacuum." Discuss the psychological weight of the black surface before beginning the subtraction.
02 Solvent Disturbance (45 mins)
Introduce solvents. Demonstrate how alcohol lifts ink differently than water. Encourage "controlled accidents"—dripping, spraying, and blotting. The focus here is on the chemical reaction between the liquid and the dried pigment.
03 Abrasive Excavation (60 mins)
Shift to mechanical removal. Use steel wool for soft highlights and blades for sharp, linear light. This is where the form begins to "emerge" from the density. Remind students: every mark they make is an act of bringing light into the world.
Conceptual Provocation
"If drawing is the addition of thought to a surface, then subtraction is the excavation of history. What are you digging for in the darkness?"
Critique Focus
Analyze the "ghost marks"—areas where the pigment wasn't fully removed. How do these residual traces contribute to the narrative of the image?

01. The Ground Construction
Describe your substrate preparation. What materials did you use to create the "total vacuum" of the surface?
02. Solvent Reactions
Record the effects of different solvents (Alcohol, Acetone, Water) on your specific pigment ground.
03. Mechanical Removal
Note the mark-making quality of different tools (Steel wool, blades, erasers). Which felt most expressive?
Conceptual Reflection
The "Ghost" Presence
Identify an area in your work where pigment was partially removed but left a stain. What does this "history" suggest about the subject of your piece?
Emergence vs. Creation
How did the act of "revealing" light change your psychological approach compared to the traditional act of "adding" marks to a white page?

Experimental Materiality // Lesson 02
Painting as Reaction
In this methodology, we abandon the brush as a tool of precision and embrace the medium as an independent agent.
Viscosity: Resistance to flow.
Surface Tension: Molecular "skin."
Adhesion: Bond between layers.
Viscosity Control
Heavy Body
High internal friction. Retains peak and texture. Conceptual weight: Stability, rigidity.
High Flow
Low internal friction. Ink-like behavior. Conceptual weight: Movement, transience.
Pouring Mediums
Extend pigment without losing structural integrity. Creates "suspension."
Chemical Conflict
Creating "Cells" and Disruptions
Si
Silicone Oil
Hydrophobic interference. Pushes water-based acrylics away to reveal underlying layers. Creates organic, biological "cells."
Al
Isopropyl Alcohol
Breaks surface tension rapidly. Causes "fracturing" or snowflake-like spreads in wet paint. Evaporative cooling affects drying.
The Zero-Contact Prompt
"Paint without touching the canvas. Use gravity, breath, and chemical reaction as your only brushes."

The "Controlled Accident" Reflection
Which combination of materials yielded the most unpredictable result? How did you attempt to "guide" this unpredictability?
Structural Integrity vs. Visual Effect
As the paint dries, observe the topographical changes. Does the "rivering" or "crazing" feel intentional or purely mechanical? Explain.

Archival Stability
• "Fat over Lean" rule: Never apply water-based media over oil-based media once cured.
• Mechanical Bond vs. Chemical Bond: Gels create mechanical locks; incompatible resins may delaminate.
• Inter-coat Adhesion: Sand non-porous surfaces between layers of heavy gel.
Material Toolkit
• Pumice Gel (Fine/Coarse)
• Fiber Paste (Paper-like)
• Glass Bead Gel
• Masking Fluids / Liquid Wax
• Cold Wax Medium
• Found Collage (Non-acidic)
• Heavy Body Acrylics
Protocols for Resistance
1
The Hydrophobic Mask
Apply liquid wax or heavy cold wax medium in sharp, expressive strokes. Once set, wash over with high-flow ink. The "shatter" effect occurs at the perimeter. This creates a conceptual wall—an area where the surface refuses to integrate.
2
Topographical Build-up
Layer Pumice Gel mixed with pigment using palette knives. While wet, press industrial collage elements (mesh, wire, torn canvas) into the paste. The medium acts as both pigment and structural adhesive.
3
Substrate Disruption
Slash and re-stitch the substrate before painting. Use the physical "wound" of the canvas as a site for heavy impasto application. Explore the "scarring" that happens when paint bridges a physical gap.
"The 'edge' is where meaning is most volatile. We are looking for the friction between the seen and the felt, the liquid and the solid."
Critique Focus
Evaluate the 'tactile narrative'. Does the texture describe the history of the work's making?

Lesson 04 // Material Memory
The Haunted Substrate
A substrate is never a "blank" space. It carries the history of its manufacture, its previous use, and its inherent physical decay.
Temporal Resonance
How old is the surface? What era does it represent?

Is it raw material or reclaimed waste?

The Context Shift
Analysis of the Portrait Subject
Fine Linen Canvas
• Suggests institutional value.
• Subject is "archived" and "elevated."
• Neutralizes physical time.
Rusted Car Door
• Suggests trauma, discard, and grit.
• Subject is "vulnerable" or "exposed."
• Emphasizes physical decay.
The Hook
"If the paint is the soul of the work, the substrate is its biology. How does your choice of surface challenge the truth of the imagery you apply to it?"
