Construction Technique
In a related process called soldering, the filler metal, usually a lead-tin alloy, remains well below the approximate 1200 degree Fahrenheit temperature of the silver based alloy used in brazing. Brazed joints are stronger than soldered joints. Brazed joints are highly reliable and are used extensively where the strength of the joint is very important. (From the Encyclopedia Britannica) ONLY BRAZED JOINTS MADE WITH A SILVER BASED BRAZING ALLOY ARE USED IN THE CONSTRUCTION OF ALL SNOWFLAKE METALWORK PRODUCTS.

Brazing
is a process for joining two pieces of metal that involves the application
of heat and the addition of a filler metal. This filler metal which
has a lower melting point than the metal to be joined is fed into the
joint as the parts are heated. In brazing parts with small clearances,
the filler is able to flow into the joint by capillary action. The temperature
of the molten filler, when it is a silver based brazing alloy, is approximately
1200 degrees Fahrenheit. The brazing alloy and the surrounding metal
parts are heated by means of a torch using a mixture of oxygen and acetylene.
