Plywood has been made for thousands of years; the earliest known occurrence of plywood was in Ancient Egypt around 3500 BCE when wooden articles were made from sawn veneers glued together crosswise. This was originally done due to a shortage of fine wood. Thin sheets of high quality wood were glued over a substrate of lower quality wood for cosmetic effect, with incidental structural benefits. This manner of inventing plywood has occurred repeatedly throughout history. Most high quality English furniture makers working in the eighteenth and nineteenth centuries (and since) have used veneering as a technique. In addition to making the most out of the highest quality materials available, it reduces prices and improves stability of construction. The irregularities of grain which confer decorative interest often result in uncontrollable warping and cracking if any attempt is made to use the wood in thicknesses much greater than those characterizing cabinet-making veneers (typically 1-2mm).
