Observation Record of Environmental Impact on Volatile Liquid Flow and Drying Processes

In long-term observations of volatile liquids, alongside the liquid itself, diluents, substrates, heat tools, and human operations, the natural environment constitutes a set of continuously present background conditions. Long-term records across different seasons, weather conditions, ambient temperatures, humidity levels, and times of day show that natural environmental variables have very limited impact on the core flow and mark-making behavior of volatile liquids. Although present throughout the entire process, they do not consistently or noticeably alter the primary form of the liquid. Therefore, in observation records, natural environmental factors are better suited to be recorded as "background conditions" rather than "primary variables."

Observation Baseline Under a Fixed Geographical Location All observation records were conducted in a relatively fixed geographical location, without long-term cross-regional or international relocation. This means that seasonal changes, climate fluctuations, weather shifts, and temperature or humidity variations experienced during observation are natural time-based progressions within the exact same baseline environment, rather than variables driven by regional geographical differences.

Background Expressions of Seasons and Climate When a volatile liquid is inside a sealed container, the liquid is isolated from the external environment, and no signs of seasonal impact have been observed. In open environments, records across all four seasons (spring, summer, autumn, and winter) and under varying climate conditions show that no season or climate fundamentally alters the basic flow and shrinkage behavior of the liquid. Climate acts primarily as a long-term background environment.

Indirect Role of Weather and Air Environment Under varying weather conditions—including sunny, cloudy, rainy, snowy, and windy days—the basic behaviors of volatile liquids show no essential differences. Adverse weather primarily affects indoor ventilation and air circulation. Because volatile liquids carry a noticeable scent, weather shifts act mainly on the observer's breathing comfort and environmental judgment, indirectly influencing the observation process rather than directly altering the liquid dynamics themselves.

Limited Impact of Humidity Fluctuations Air humidity fluctuates frequently across seasons, weather conditions, and times of day. However, across long-term records under varying humidity conditions, humidity has shown no capacity to cause consistently noticeable differences in liquid behavior, nor can it stably account for any major mark-making phenomena.

Distinction Between Ambient Temperature and Applied Heat Under higher room temperatures, thinner liquid edges exhibit faster boundary movement and enter the drying stage earlier. Ambient temperature has a directly observable impact on accelerating localized evaporation and drying progress. However, ambient temperature cannot stably govern line formation, overall flow paths, or primary structural forms. Ambient temperature is a global background covering the entire space, whereas heat applied by heat tools is an active, localized, and directional variable, with a clear boundary separating the two in nature.

Minor Differences Across Times of Day In observations conducted across different times of day—morning, noon, afternoon, and night—no regular or systematic differences in liquid behavior were observed. Shifts in the time of day primarily affect ambient air circulation and human physical comfort, indirectly determining whether an observation takes place and the environmental conditions during that observation.

Action Path in the Behavioral Preparation Phase Before liquid behavior begins, weather, time of day, and ventilation conditions act upon the environment and the human state, primarily influencing whether an observation is initiated, as well as operational comfort and environmental judgment.

Action Path in the Behavioral Dynamic Phase During the dynamic movement of the liquid, temperature, humidity, weather, and time of day exist alongside liquid behavior as background conditions. Apart from ambient temperature accelerating localized evaporation and drying speed in specific cases, the direct impact of other factors on primary liquid behavior remains very limited.

Action Path in the Mark Preservation Phase After liquid movement ceases and the marks solidify, environmental exposure (especially strong light and direct sunlight) exerts a subsequent influence. For example, extended summer exposure to direct sunlight can lead to color shifts, fading, localized color variation, or changes in surface condition. In this phase, environmental factors act upon physical preservation rather than the dynamic behavior of the liquid itself.

The natural environment is an external system spanning the entire observation process of volatile liquids. Compared to core factors such as liquid composition, concentration, substrate properties, or heat guidance, environmental factors present a "background" and "indirect" character overall. Throughout the behavioral process, only ambient temperature fine-tunes localized evaporation speed; once the liquid stops flowing and solidifies, strong light and direct sunlight become key external variables determining whether the remaining marks can be stably preserved over the long term.
