Modern-day chalkboards have gone through a lot of changes through the years. The earliest chalkboard was a small slate with wood frame. Students used the chalkboard as a substitute for paper, which was quite expensive. These boards were later enlarged enabling them to be mounted on classroom walls. They were sent to school all over the United States and revolutionized the way classes were taught. Teachers found them very convenient as they could present lessons visually.
Today, real the original slate chalkboards are fairly much obsolete, and they’re a find for collectors. It’s though that the chalkboard was the idea of a geography teacher in the early 1800. It was used at West Point for numerous years before being replaced with the now popular whiteboard.
The whiteboard is what you find in most schools these days. Teachers and students prefer it to the chalkboard because it is clean – no chalk involved. The markers used to write on the board wipe off very easily with a cloth and come in many vibrant colors.
Unfortunately, the ancient antique chalkboards are being covered up with porcelain whiteboard skins, or framed whiteboards are being mounted right over the ancient chalkboards. The methods are used, because removing old chalkboards can be quite a task, not to mention an expensive endeavor. It is much simpler to cover upward the ancient board and replace it with brand new whiteboard.
One option is installing porcelain whiteboard skins. This does not involve manually removing the antique chalkboard. Whiteboard skins are extremely razor-sharp and require much welding from a professional. The old chalkboard should be treated and cleaned properly for the new contact cement to hold firmly. This process, however, can be costly.
Another option is mounting a framed whiteboard over the antique chalkboard. This is fairly easier than installing whiteboard skins and is not really that costly. The new whiteboard just needs to be drilled and installed over the antique chalkboard. A major drawback, however, is that a relatively big amount of writing space can be lost.
