as A Paper Substitute
- Blackboard classroom history begins, in rudimentary form, in ancient times. Students in ancient Babylonia and Sumeria inscribed their lessons on clay tablets with a stylus (predecessor to the pen and pencil) in cuneiform writing. These could be used wet and erased to be used again, or baked to create a permanent document. In India in the 11th centu...

Changes in Classroom Efficiency
Substitutions and Modifications
- Some of the earliest chalkboards were little more than small squares of slate, usually framed with wood to keep them from breaking. Students were typically each assigned one if they didn’t own one themselves, and they used them to solve equations and compose short educational exercises. They could be marked on with other, lighter slate pencils, or ...
Modernizations
- The boom in slate usage is perhaps most profound when looking at the history of the chalkboard in the United States. Slate mining coincided with the development of the American railway system. As such, much of the mineral that was mined out of Vermont, Maine, Pennsylvania, Virginia, Maryland, and New York could be efficiently transported via railroad to the thousands o…
Whiteboard Alternatives
- Student slate boards were effective, but not particularly efficient, particularly in disciplines that required precise equations — science and math, for instance. Teachers would usually have to individually transcribe the problems onto each individual slate, which took up a lot of time. All of this changed when teachers began mounting bigger boards onto classroom walls. This leap for…
Overview
- Despite the widespread availability of slate, it was still too expensive for some of the poorer and more rural school districts. Teachers in these circumstances sometimes resorted to painting a plaster wall or wooden panel with dark paint to imitate slate, and black-painted grit sometimes also worked. An old rag served as eraser. Students sometimes came up with these sorts of crud…
Etymology and history
- The history of the chalkboard has also taken a few modern twists. Today’s scholars are more likely to find a chalkboard that is a steel sheet enameled with porcelain rather than true slate. Chalk, which is a limestone derivative, is the most common writing implement, and the rag erasers of earlier times have largely been replaced by blocks of felt that can erase chalk marks without c…
Design
- In the 1990s, concern over allergies and other potential health risks posed by chalk dust prompted the replacement of many blackboards with whiteboards. A whiteboardis a plastic board, sometimes also known as a “dry erase board,” on which people use special pens to make colored marks. These can be a cleaner, brighter alternatives to education and business interests.
Chalk sticks
A blackboard (also known as a chalkboard) is a reusable writing surface on which text or drawings are made with sticks of calcium sulphate or calcium carbonate, known, when used for this purpose, as chalk. Blackboards were originally made of smooth, thin sheets of black or dark grey slate stone.
Advantages and disadvantages
The writing slate was in use in Indian schools as mentioned in Alberuni's Indica (Tarikh Al-Hind), written in the early 11th century:
They use black tablets for the children in the schools, and write upon them along the long side, not the broadside, writing with a white material from the left to the right.
The first classroom uses of large blackboards are difficult to date, but they were used for music …
Gallery
A blackboard can simply be a board painted with a dark matte paint (usually black, occasionally dark green). Matte black plastic sign material (known as closed-cell PVC foamboard) is also used to create custom chalkboard art. Blackboards on an A-frame are used by restaurants and bars to advertise daily specials.

Sticks of processed "chalk" are produced especially for use with blackboards in white and also in various colours. White chalk sticks are made mainly from calcium carbonate derived from mineral chalk rock or limestone, while coloured or pastel chalks are made from calcium sulphate in its dihydrate form, CaSO4·2H2O, derived from gypsum. Chalk sticks containing calcium carbonatetypically …

As compared to whiteboards, blackboards still have a variety of advantages:
• Chalk requires no special care; whiteboard markers must be capped or else they will dry out.
• Chalk is an order of magnitude cheaper than whiteboard markers for a comparable amount of writing.
