Browsing the OED is a tantalizing experience because it provides windows into so many obscure corners of history. But since the citations are small and fragmentary, they invite the imagination to fill in the blank spaces.

Did baking ruin the type? Did each printer have his own method to prevent baking, a trade secret he passed down only to his apprentice?
