The oldest examples of glass discovered in the tombs of Egypt and Assyria are in the form of beads, scarabs, amulets, etc. for personal decoration, while glass objects such as bottles, cups and vases came at a later date.In Egypt, the first glass we know of, as a component of faience ware, dates from as far back as the Neolithic Badarian culture at the turn of the 5th and 4th millennia BC. Glass is produced from a mixture of silica-sand, lime and soda, colored with the copper ore malachite and fused at a high temperature.

Efficiency: Once users have learned the design, how quickly can they perform tasks? Memorability: When users return to the design after a period of not using it, how easily can they reestablish proficiency? Errors: How many errors do users make, how severe are these errors, and how easily can they recover from the errors? Satisfaction: How pleasant is it to use the design?

8Poor Usability“Questions about whether design is necessary or affordable are quite besidethe point: design is inevitable. The alternative to good design is bad design,not no design at all.Everyone makes design decisions all the time without realizing it ...gooddesign is simply the result of making these decisions consciously, at the rightstage, and in consultation with others as the need arise."Douglas Martin

(Plato) Usability testing is the killing field of cherished notions. - David Orr We cant solve problems by using the same kind of thinking we used when we created them. - Albert Einstein The joy of an early release lasts but a short time. The bitterness of an unusable system lasts for years.
