To maintain the life of your glass investment you obviously need to treat and handle it carefully. The tips we mention on this page are designed to improve handling of glassware by reducing the most common causes of damage; mechanical and thermal shock.
1. Thermal shock
Thermal shock is the result of glass experiencing a sudden temperature change. Glass holds temperature and a rapid change in temperature can cause enough stress to result in breakage.
For example, a glass that has held ice cannot go directly into the dishwasher; a glass warm from the dishwasher should not go directly into service; and cold water or ice should not be put into a warm or hot glass or cup. In all cases, the glass needs to reach room temperature before being taken to the other extreme, and the thicker or heavier the item, the more time is needed. Cracks that result from thermal shock usually form around abrasions caused by mechanical impact, increasing the chances of breakage.
2. Mechanical shock
Mechanical shock in glassware is the direct result of contact with another object, such as a spoon, a beer tap, another glass or a piece of china. This kind of contact can cause a minute abrasion, invisible to the eye, but a source of weakness in the glass, making it more susceptible to breakage from impact or thermal shock.
