In , Edward Malone published a refutation of this document.

He reasoned that an author of Shakespeare’s caliber who was also famous and affluent at the time Lear was written, would have gone to a papermaker and secured as much paper of one type as was needed for his work.
But someone who wanted to forge an Elizabethan play years later would ferret out such scraps of old paper as he could – from the flyleaves and blank pages of old manuscripts.

There’s more to a piece of paper than meets the eye – and paper analysis can find it. This specialized investigative process extracts historical and physical evidence from documents, photographs, art prints, books, and other paper-based objects. These tools are used, alone or in combination, to characterize the properties of paper in a number of ways. For example, a qualitative analysis shows what materials are in the paper, fiber, ink; quantitative analysis measures how much.
Chemical analysis evaluates composition and pH; physical analysis measures gloss, strength, color. Organic analysis detects carbon-based traces of plants and organisms; while inorganic analysis identifies mineral evidence in pigment and ink. Each of these approaches provides a set of facts about an artifact’s condition, age or origins. The method of choice for any given situation is determined by several factors, including: the objectives of the investigator authentication, preservation, personal curiosity ; the relative value of the paper historically, legally, personally ; and whether the information gained from destructive testing will outweigh the loss of material samples.
