Coloured chalk is a versatile and widely used writing and drawing medium commonly found in classrooms, art studios, training centres, and creative workspaces. Made primarily from calcium sulfate or calcium carbonate, coloured chalk is produced in a range of vibrant hues that enhance visibility and allow users to create clear, eye-catching displays on chalkboards and other suitable surfaces. Its smooth texture enables easy writing and shading, making it popular with teachers, artists, and presenters.
