A China marker, also known as a grease pencil, China pencil, or wax pencil, is a versatile writing and marking tool commonly used in various fields such as art, manufacturing, and education. Unlike standard pencils that use graphite as their core, China markers have a core made of a pigmented wax or oil-based material, allowing them to write on a variety of surfaces, including:

Glazed ceramics
Glass
Metal
Plastic
Paper
Wood

Features of China Markers:

Marking Capabilities: They can produce bold and opaque lines, which makes them suitable for both fine detail work and broad strokes.
Removable Marks: Many China markers are designed to be easily erased with a damp cloth, which is useful for temporary markings.
Color Variety: They are available in numerous colors, allowing for creative expression and clear distinction in marking.
No Sharpening Needed: China markers often come in a tubular form, much like a crayon, and can be advanced by twisting or pulling the end to expose more of the writing material, avoiding the need for sharpening.
Durability: They are weather-resistant and do not smudge easily, making them ideal for both indoor and outdoor use.

Applications:

Art Projects: Artists use China markers for drawing, sketching, and adding details to various artworks.
Manufacturing: They are used for labeling parts or creating marks on surfaces where conventional markers may not work.
Education: Teachers may use them on boards or transparencies for demonstrations.

Overall, China markers are a handy tool for anyone needing reliable and versatile marking options across different mediums.
