The three grades (when used in jewellery making) are: 'Easy', 'Medium' and 'Hard'.
These refer to the temperature that the solder melts - 'Hard' is the highest, 'Easy' is the lowest.
The different grades allow a joint to be soldered, next to an existing joint. Thus you would normally use 'hard' first, then 'medium', and finally 'easy'.

How do silver melt down?
Heat the object to the melting point of silver, which is 1763 degrees Fahrenheit (962 degrees Celsius).Heat the furnace to a temperature which exceeds the melting point of silver.Break large silver objects into smaller pieces and melt them in small batches to allow a more even distribution of heat which results in a quicker melting process.Places the pieces of silver into the crucible and maintain the heat of the furnace until all silver items have been melted.Lift the crucible with heat resistant tongs and pour the silver into prepared molds while the silver is liquid. You must complete this step quickly in order to prevent the silver from reverting back to a solid state while within the crucible.
What are equivalent grades of 070M20?
The grade 070M20 is a low-carbon structural steel commonly used in construction and engineering applications. Equivalent grades include S235JR according to EN 10025, and ASTM A36 in the American standard. These equivalents share similar mechanical properties, making them suitable substitutes in various applications. Always verify specific requirements and standards for the intended use.
Is silver used in manufacturing?
Silver, symbol Ag, is a shiny metallic element used for ornamental and coinage purposes since the ancient times. It is next only to gold in terms of malleability and ductility, and is also a good conductor of heat and electricity. In fact, silver is the best conductor of electricity, better even than copper and gold. Silver, like gold, is used in many facets of semiconductor manufacturing, again more particularly in the assembly or packaging processes. Most epoxy die attach materials contain silver fillers for increased thermal and electrical conductivity. Silver is also used to cover the surfaces of the die pad and bonding fingers of the leadframes of plastic packages to prevent chemical degradation of these areas, which may lead to die attach and bonding problems.Source: http://www.siliconfareast.com/semicon_matls.htm

Where can someone learn how to silver solder?
There are plenty of guides on silver soldering online. Sites such as wikiHow provide step by step guides to silver soldering, however it may be a better idea to watch an informal video with a practical guide on sites such as YouTube, Vimeo or DailyMotion instead.
How hot does the fire torch need to be when silver soldering?
Silver soldering typically requires a torch with a temperature range of 1300-1600°F (704-871°C) to melt the solder and create a strong bond between the metals.
Is there different grades of silver?
yes

How can I effectively solder a silver chain?
To effectively solder a silver chain, you will need a soldering iron, silver solder, flux, and a steady hand. First, clean the chain and apply flux to the area you want to solder. Next, heat the soldering iron and melt a small amount of solder onto the joint. Finally, carefully heat the joint with the soldering iron until the solder flows and creates a strong bond. Allow the joint to cool before handling the chain.

What sterling silver to use for soldering jewelry?
Typically one solders sterling silver with silver solders. There is not a solder called "sterling solder." You can choose from an array of silver solders ranging from easy (extra soft) through hard. Soft solders have lower silver content and melt at a lower temperature. Hard solders have higher silver content and flow at higher temperatures. If you are doing multiple solder joints on a single piece of solder you will need to use several grades of solder. However, if you are just creating a single solder joint than it is best to use a soft or medium solder.
Can gold be soft soldered?
Yes it can. It actually has a lower melting point than silver, so it can be manipulated with a commerical soldering iron.
What is the value of a three cent coin 1852?
The 1852 Silver Three-Cent Piece is the highest mintage coin of this series. Because it's the smallest US silver coin, the condition is very important, coins that are bent, cleaned or have been used as jewelry have almost no value. Average retail values run from $25.00-$45.00 in the lower grades and $50.00-$150.00 in EF-40 to AU-50 grades. Uncirculated coins are $160.00-$200.
