Frequently we attempt to explain the facts of Murano glass artisanship to customers seeking flawless perfection in the tableware merchandise they buy. Of course, this is not possible or even desirable in quality ware whose manufacture depends so much on the skill and artistry of individual craftsmen. 
Slight variations in Murano glassware pieces are actually a confirmation of fine crafting. Most customers who appreciate fine Murano glass understand this. 
 


Is a bubble in Murano glassware a flaw?
No. The tiny bubbles, visible when you examine crystal against a strong light, are formed by gases when chemicals unite in the fusing or melting of the raw ingredients. These bubbles do not affect the quality or the beauty of the glass. 
 


Should all pieces of crystal be identical?
No. Each piece of glass is unique. Slight variations of weight and sometimes of dimension are a sign that each piece truly is individually crafted. 
 


Is a line or “cord" a flaw?
A line or "cord" is an almost invisible difference in the density of the glass that occurs during the fusing of molten glass. It is visible when it reflects light. But when a goblet with a cord in it is filled with water, no light is reflected, and the cord becomes invisible. 
 


How can I remove stains from a decanter or a vase?
Clean decanters by filling them half-full with moderately hot water, a small amount of mild detergent, two tablespoons of white vinegar or ammonia and a cup uncooked rice. Swirl the rice around for a few minutes to remove residue. Rinse well with moderately hot water and air dry, upside down, on a rack. 
 


Can crystal be cleaned in a dish washer?
NO, Murano glassware should not be put in the dishwasher as the heat and abrasive cleaners may mark its surface and can damage gilting or gems. Our objects need to be washed by hand.
