The use of Slates
They were advertised in newspapers as early as 1737. Slates with wooden frames were advertised in 1749.
It’s often hard to tell how old a particular slate might be. They are still manufactured today and have been a popular toy off and on over the years. Perhaps the best way to determine the age of a slate is from the frame. The frames of older slates were often handmade from better wood and had fitted dovetail corners. Newer slates typically are framed in pine and are held together with small nails.
