Dry Erase Message Boards

Dry Erase Message Boards sure come in handy at times. The Chalkboards, with their greenish cast and dustless chalk, have gone through many stages of advancement. Chalkboards initially were small squares of slate, framed with wood, and markings were made on with other shards of slate. In the nineteenth century America, these elementary instruments were widely used in schools, as the paper was expensive.

A revolution occurred when a geography teacher in Scotland was reputed to have found a replacement for these dusty slates. The earliest record in America shows their usage dated back to 1801in academic military schools. Instructors no longer had to spend much of time writing on each student's slate, but could teach to an entire class with illustrations on the board, where everyone had the benefit of seeing it.

Slate, a dark metamorphic rock, was dug out in various states such as Vermont, Maine, Pennsylvania, Virginia, Maryland, and New York and was in great demand. By 1850s, most single block schools were outfitted with the staples, a wood burning stove, benches, and a large blackboard.

In poorer and remote schools, teachers resorted to painting a plaster wall or wooden panel with black paint to imitate the slate and an old rag was used as an as eraser. Each school could accommodate more students and taught them more efficiently with help of illustrations. In the 90s, due to concern over allergies and other health risks posed by dusty chalk encouraged to bring in the substitute of many blackboards with whiteboards.

A whiteboard also called as dry-erase or dry-wipe board and has a glossy surface, commonly colored white, where the non-permanent markings are made. Whiteboards are similar to chalkboards and the markings temporarily adhere to its surface. The use of whiteboards has increased and they have become a necessity in many offices, meeting rooms, classrooms, and other interactive environments.

One can use markers of various color instead of using chalks, a special whiteboard erase marker which has a removable ink is used. Whiteboards are made of either melamine resin, polyester coated steel or expensive models made from porcelain enameled steel. The usage of the white board is extended when it's made of steel. These are magnetic, and we can use magnets to affix notes or any other info on them. Boards made of porcelain are durable than the other two.

As the ink of markers enter the pores of the material, the boards made out of melamine resin and painted steel will fade to a slight gray color over time. But the porcelain and vitreous enamel are impermeable for marker ink and remains white throughout the lifespan.

Ask any tutor or corporate trainer, and they will tell you why dry erase white boards are handy tools. This can be really useful when you want to jot a few quick notes, scribble a math formula and wipe it clean. In fact, a dry erase board is great medium for teaching, training, scribbling or just about anything else.
