THE WAX TABLET
Wax Tablets were used for thousands of years, from at least the time of the Greeks until the middle of the nineteenth century. To a good extent, they were medieval PDAs, where you could mark down notes, sums and other information that might be transferred to a more permanent medium or just “erased” and written over.
The original tablets came in a variety or sizes and ratios, and the size was dependent on personal need or taste. Sometimes, there were more than one pane on each side of the tablet. Most of these were apparently used in business.
Styluses were apparently anything that would mark wax: dedicated metal or wood styluses, broken arrows and much else. Many had a flattened end, which was used to erase, that is, to smooth over the wax. When the wax became too choppy and unsmoothable, the wax could be melted, so you could stop from scratch—pun intended—with the writing surface.
It is unknown whether wax tablets were used in “illiterate” cultures, though none have found.
Making a Wax Tablet
Choose two pieces of wood, preferably a hard wood with no holes, of the size you want. The boards should be about a quarter or half an inch deep. Sand them and stain or varnish them.
Using a router or a chisel, a depression should be made in the center of each panel. The depth is up to you, but it should neither be so shallow that marks can be made nor so deep that it goes through to the other side of the board. There is really no need to sand or smooth the depression, since the irregularities help keep the wax in place.
Melt 100% bee’s wax. When it has been melted stir in some carbon black to it to help visibility. The amount is up to you. Either make the carbon black manually by scraping soot off a ceramic or other such item (I would make the soot by burning a lighter against a plate and scraping the soot off; tedious!), or buy a can of carbon black from a paint store (much less time consuming). When the wax and the carbon black have been integrated and melts, the mixture should be pour into the depression. It should smooth and to the corners (the drying usually means there will be a gap). If necessary, use a pencil or dowel to smooth it out; the hardened wax may be easily rubbed off where it does not belong.
Set it out on an even surface to dry.
You might want to drill holes for leather thongs to hold them together, either before after the wax is poured.
A stylus of the desired type can be included with the tablet. On my first few, I drilled a hole in the stylus and attached it by a cord to the tablet so that I did not lose it!
