Reading Books and Prints as Cultural Objects index versus double refraction. With the aid of this diagram a mineral can be searched for, of which the optical characteristics are known by measurements. In differential thermal analysis it will be much more difficult than in optics to develop a similar introductory diagram. But on principle it i
