Observation Records on Material Mixing Behaviors

In long-term observations of different art materials, mixing behaviors vary significantly between different systems. When materials are mixed, their original internal structures, visual characteristics, and usable states may remain stable, or they may change—sometimes even resulting in irreversible state transformations.

This record is strictly limited to material combinations that have actually been tested. No inferences or predictions are made for untested combinations.

1. Mixing Observations Within Same-Material Systems

Alcohol Ink Systems

The internal mixing of alcohol inks and alcohol-based liquids reveals clear limitations and compatibility differences.

• Apparent Form Changes: In mixing tests between different alcohol inks, or between alcohol liquids and various diluents, certain combinations form precipitates, particles, flocculent structures, or residue-like deposits upon contact. These solid particles are not visible in the individual liquid components prior to mixing; they form only after contact.
• Behavioral and Visual Impacts: The resulting precipitates and larger particles directly enter the fluid motion and flow process. On non-absorbent substrates, these particles become visible impurities, disrupting the continuous flow structure or leaving noticeable marks.
• Irreversibility: The formation of such precipitates and large particles is irreversible. Once formed, these solid structures cannot be reverted to a uniform liquid state. In practical testing, mixtures with significant precipitation can no longer be used as standard painting liquids.

Powder Pigment Systems

The mixing performance of powder pigments is closely linked to their intended purpose.

• Art-Grade Pigments: Powder pigments designed for color making can be mixed together in practical operations. However, the outcome depends on the specific pigment's coverage and visual properties; mixing does not automatically improve visual performance. For example, mixing a metallic pigment—known for strong coverage and bright reflective shine—with a chameleon pigment causes the metallic pigment's visual weight to block or dull the color-shifting effect naturally seen in the chameleon pigment.
• Independent Tests on Industrial Pigments: Industrial-grade powder pigments originally designed for plastics and other industrial systems were tested independently. Their material texture differs significantly from the standards required for art pigments, making them unsuitable as raw materials for handmade paints. Therefore, no further mixing tests were conducted between industrial-grade and art-grade pigments.

Handmade Watercolor Paints in Application

Solid handmade watercolors that have been processed and cured show high stability during color mixing and painting.

• Stability Performance: In testing different watercolor paint mixtures—including combinations of metallic watercolor with standard watercolor paints—no severe clumping, material failure, heavy precipitation, or degradation was observed.
• Scope Boundary: Within the scope of tested painting applications, solid watercolors display relatively stable contact behavior during color mixing and use.

Acrylic Systems

Observations were conducted on acrylic materials across different forms (fluid, heavy body), different brands, and mixtures incorporating various flow mediums or water.

• Observed Changes: After mixing, acrylic materials primarily exhibit changes in color, viscosity, coverage, and fluidity, forming a new material state.
• Stability Performance: Within tested combinations, no severe precipitation, large particle clumping, or irreversible failures that render the material unusable were observed.

Oil Pastel Systems

Direct mixing and layering tests were conducted using oil pastels across different brands, colors, and textures.

• Contact Performance: When oil pastels are blended together or applied in overlapping layers, no severe clumping, crumbling, or material failure occurs.
• Primary Changes: The process mainly results in new color blends and adjustments to surface hardness and coverage, maintaining high stability during physical contact and blending.

2. Cross-Material Mixing Observations

Cross-material testing shows that when different material systems meet, their performance ranges from shifts in visual character to complete operational failure.

• Alcohol Ink + Powder Pigment: Direct mixing of alcohol ink and powder pigment yields poor results. Because alcohol is a highly volatile liquid that lacks binder properties, the mixture fails to form a stable structure and cannot be used as a standard paint.
• Powder Pigment + Acrylic: Mixing powder pigment into an acrylic system causes no obvious failure; the material remains fully operational and usable for application.
• Handmade Watercolor + Acrylic: Mixing acrylic into watercolor during painting causes no clumping or structural failure. However, because acrylic carries strong visual opacity and surface weight, it covers the original transparency of watercolor, leaving the finished artwork dominated by acrylic characteristics.
• Oil-Based Oil Pastel + Water: When oil-based oil pastels come into contact with water, they do not merge or form a workable state. Water cannot alter the solid properties of oil-based pastels, making this combination impossible to work with.
• Alcohol + Water: Mixing tests between alcohol and water yield poor results, failing to establish a stable material behavior state.

3. Summary of Material Mixing Behaviors

Based on actual observations, the tested material combinations present the following characteristics:

4. Summary and Boundaries of Observation

1. Mixability Does Not Equal Feature Retention: A material combination that can be mixed without structural failure does not guarantee that both original visual traits will remain intact. Materials with high opacity or visual weight tend to weaken or hide the characteristics of the other material.
2. Visual Changes Do Not Equal Material Failure: Shifts in color, fluidity, coverage, or surface texture simply represent the formation of a new material state. A material is defined as "failed" only when it produces irreversible large particles, heavy precipitation, or becomes unspreadable.
3. No Assumptions for Untested Combinations: For material combinations that have not been physically tested (such as alcohol with oil pastels, or alcohol with acrylics), no inferences or predictions are made regarding their mixing behaviors.
