Here we examine some advantages and disadvantages of several types of glass and why one type of glass stands out as the practical choice for new glassblowers. soda lime glassgroup 10introductionSoda-lime was produced throughout much of Europe for hundreds of years. Lead crystal has several desirable attributes, including a higher index of refraction (the way in which light reflects within the glass) and the fact that it is softer when cold, allowing it to be more easily cut and engraved. Even when it does break, it breaks in larger, duller pieces. Discussion . . Cons/Disadvantages of Wired Glass: Most people think that the placing of wire into the glass makes it stronger, but in fact, the wire in the glass actually weakens the glass from the strength standpoint and makes it more susceptible to breaking. For example, everybody has experienced a glass breaking down when pouring liquid at high temperature, for example to make tea. Glass has proved to be a building material that drives designers to mobilize it while creating various designs forms and spaces. Cheeseman, C. Fountzoulas, P. Patel, D.W. Templeton, and K.D.
