I'm a specialist in the field of combustion and material science. When it comes to the burning of materials and the smoke they produce, it's a complex process that involves various chemical reactions and the properties of the material itself.
When a substance burns, it undergoes a chemical reaction with oxygen, a process known as combustion. The byproducts of this reaction can include heat, light, and smoke. Smoke is a mixture of gases and particles that are produced when a material is heated to the point of combustion. The color and composition of the smoke can vary greatly depending on the type of material being burned.
White smoke in particular is often an indication of the presence of moisture. When a material that contains water or is otherwise moist is burned, the heat of the fire causes the water to evaporate rapidly. This evaporation can produce a visible cloud of steam, which appears as white smoke. This is a common phenomenon with materials that are high in moisture content, such as wood that has not been properly dried.
However, the presence of white smoke is not solely due to moisture. Other factors can contribute to the production of white smoke as well. For instance, certain chemicals or substances within the material can react with the heat and oxygen in the air to produce specific compounds that appear as white smoke. This can occur with a variety of materials, including but not limited to plastics, certain types of rubber, and even some types of paint or coatings.
It's also important to note that the color of the smoke can change as the material continues to burn and as the combustion process progresses. Initially, the white smoke may be due to the evaporation of moisture, but as the material dries out and breaks down further, the smoke may take on a different color. For example, as mentioned in the provided reference, wood materials may change to a tan or brown color as they burn, indicating the presence of different compounds and the progression of the combustion process.
Plastics and painted or stained surfaces, on the other hand, can emit a gray smoke. This is often a result of the mixing of moisture and hydrocarbons. Hydrocarbons, when burned, can produce black smoke, but when mixed with the moisture content of the material, the smoke can appear gray.
In summary, the production of white smoke when a material is burned is a multifaceted process that can be influenced by the moisture content of the material, the presence of certain chemicals or substances within the material, and the progression of the combustion process itself. Understanding the specific conditions and the material being burned is crucial to accurately interpreting the color and composition of the smoke produced.

This white smoke is mostly moisture. As a material dries out and breaks down, the color of the smoke changes. Wood materials change to tan or brown, whereas plastics and painted/stained surfaces emit a gray smoke, as a result of the mixing of moisture and hydrocarbons (black).Sep 1, 2005
