With much gratitude to the waxed tablet links on Larsdatter.com I conducted some research into making a waxed tablet. There are variations in the number of leaves in the tablets; I chose to use the fewest number, two, because the end result would be less bulky and also easier to construct.
I chose quarter sawn white oak as it is the most similar to European oak commonly used in the period, has pretty grain, and because it is quarter sawn is more stable and less likely to warp.
Different colors were used to mix with the beeswax in extant tablets including black, red, and yellow. I decided on red because I had a large amount of the pigment, thought it would look good, and work well enough when written upon.
The linseed oil and wax finish is a period appropriate finish and looks very good. This was my first time using linseed oil and I was extremely pleased with the result. The oil really brought out the beauty of the wood grain. I am now completely sold on using it in a finish and looking forward to trying it under shellac. Here's what it looks like in full sunlight:
