As an expert in the field of material science with a focus on natural materials and their properties, I can provide you with an in-depth analysis of the flammability of used wine corks.
Cork, derived from the bark of the cork oak tree, is an interesting material with a unique structure and a variety of applications. It's widely used for wine bottle stoppers due to its elasticity, impermeability, and ability to maintain a tight seal. However, the question of whether used wine corks are flammable is a nuanced one.
In its natural form, cork is indeed a very good fire retardant. This is due to its complex cellular structure, which is composed of a waxy substance called suberin. This substance is hydrophobic and provides a natural resistance to fire. The cells are filled with air, which is a poor conductor of heat and further enhances the fire-resistant properties of cork. When exposed to a flame, the cork will char on the surface but will not easily ignite or propagate the fire.
However, it's important to note that the flammability of a material can change depending on its form. For instance, cork dust, which is the fine particles produced when cork is processed or ground down, is actually extremely flammable. This is because the cell structure of the cork has been broken down, and the individual particles can easily catch fire. The small size of the particles increases the surface area in contact with oxygen, which can lead to rapid combustion.
Regarding the impermeability of cork, it's a fascinating characteristic. The cell membrane of cork contains a "magic" chemical, as you've mentioned, which makes it completely impermeable to liquids and gases. This is one of the reasons why cork is an excellent choice for wine stoppers, as it prevents the wine from leaking out and keeps the contents fresh.
Now, let's discuss the used wine corks specifically. When a cork has been used to seal a wine bottle, it doesn't undergo any significant change in its chemical composition that would affect its flammability. It may have some wine residue on it, but this is unlikely to make a substantial difference to its fire resistance. The cork will still maintain its natural fire-retardant properties, and it would require a significant amount of heat to ignite it.
In conclusion, used wine corks, like their unused counterparts, are not easily flammable due to their natural fire-retardant properties. However, it's crucial to handle them with care, especially when they are in the form of dust or fine particles, as these can pose a fire hazard. It's always important to consider the context and form of the material when assessing its flammability.

In its natural form, cork is also a very good fire retardant, although cork dust is actually extremely flammable (because here the cell structure has been broken down). Impermeable: Cork has a magic chemical in its cell membrane that makes it completely impermeable to liquids and gases.
