Glassware must be durable. Use of expensive, fine crystal may be appropriate in certain fine dining establishments, but since the glasses will be abused and frequently handled in the beverage operation, careful selection is important. Normally, there should be a relationship between the price of the drink and the cost of the glass. As the selling price of the drink increases, the elegance of the glassware often becomes a factor in the guests perceived value. Basic procedures should be used to maintain glassware properly.
Glasses frequently break or chip because they are washed improperly.
Improper racks, hand washing, stacking of glassware, or contact with other objects can cause damage. Glassware also is affected by fast temperature changes. When a cold glass is put in hot dishwater or when ice is put into a hot glass, the sudden temperature change can cause cracks. Glasses used for hot drinks should be tempered with hot water before adding hot coffee or other liquid. An adequate supply of glassware is important because it eliminates the need for service personnel to hurriedly clean soiled glasses - haste can lead to more chipping and breaking.
