The History Committee of the Slatington 125 Celebration's "Slatington and Surrounding Communities: A Volume of History, 1864-1989" (Slatington 125 Celebration, 1989) notes that Arthur and E. L. Kraus owned the National School Slate Company until it was purchased by Babyak and Jacob Papay in 1950. The Papay family maintained its interest in the company until 1971.
School slates, individual or blackboard size, are made from a fine grain, soft slate that is darker in color than the light-gray slate used for roofing. After a school slate is split to its desired thickness, its edges are turned up by a small circular saw, face smoothed with a drawing knife and then rubbed with a cloth and fine dust compound, and eventually framed for individual use or utilized as part of a child's toy blackboard. Ruled slates generally were made for export to Continental Europe. If colored crayons were to be used in addition to chalk, one side of the slate was lacquered in white.
In 1941 there were only two school slates companies in the United States -- National School Slate Company and American Slate Works. Both were located in Slatington. National School Slate Company owned its own quarry, the Blue Ridge Quarries. It also purchased slate from other quarries in the region.
By 1941 the American market for school slates had vanished. Most Slatington school slates found their way to Central America, the Netherlands, East Indies, South Africa and South America. American sales focused largely on toy blackboards and bulletin boards sold primarily by chain stores.

A slate is a thin piece of hard flat material, such as the rock also called slate, that is used as a medium for writing. The rock is "a metamorphic rock created by the recrystallization of the minerals in shale from clay to parallel-aligned, flat, flake-like minerals such as mica".
The writing slate consisted of a piece of slate, typically either 4x6 inches or 7x10 inches, encased in a wooden frame.
A slate pencil was used to write on the slate board. It was made from a softer and lighter coloured stone such as shale or chalk.
Usually, a piece of cloth or slate sponge was used to clean it and this was sometimes attached with a string to the bottom of the writing slate.

The exact origins of the writing slate remain unclear. References to its use can be found in the fourteenth century and evidence suggests that it was used in the sixteenth and seventeenth centuries. The central time period for the writing slate, however, "appears to begin in the later eighteenth century, when developments in sea and land transport permitted the gradual expansion of slate quarrying in Wales and the growth of a substantial slate workshop industry."
By the nineteenth century, writing slates were used around the world in nearly every school and were a central part of the slate industry. At the dawn of the twentieth century, writing slates were the primary tool in the classroom for students. In the 1930s (or later) writing slates began to be replaced by more modern methods. However, writing slates did not become obsolete. They are still made in the twenty-first century, though in small quantities.
The writing slate was sometimes used by industry workers to track goods and by sailors to calculate their geographical location at sea. Sometimes multiple pieces of slate were bound together into a "book" and horizontal lines were etched onto the slate surface as a guide for neat handwriting
