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.

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.
Is there different grades of silver?
yes

What is the difference between soldering and brazing?
Soldering and brazing both join two parts by melting a different metal as an adhesive without damaging the two parts being joined. Soldering uses a different metal that has a lower melting point (usually lead-based) than the metal used in brazing (usually silver). This allows easier joining in soldering, but a stronger bond in brazing.

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 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.
What does silver solder mean?
This term is found on the back or bottom of many silver plate pieces. It simply means that components of a piece were connected together by soldering with an alloy containing silver. It does not add any significant value to a piece.
What is the best soldering iron and tip to use on circuit boards?
Soldering irons come in a variety of sizes and shapes. There is a wide selection of soldering irons, soldering pencils, soldering stations and soldering guns available on market in the USA.Which soldering iron is the best soldering iron for you depends on the soldering work you are planning to do and how often you are planning on using your soldering iron. The following four factors should be taken into consideration when picking a soldering iron that will be used for soldering projects on circuit boards:1) ) type of the soldering tools2 wattage of the soldering iron3)temperature control4) tip size and shapeTypes of soldering toolsAll soldering tools can be divided in four different groups-Soldering pencils-Soldering station-Soldering rework /repair stations systems-Soldering gunsSoldering pencilsSoldering pencils are the simplest (and the cheapest) soldering tool. Soldering pencils are good only for simple do-it-yourself projects. The price range of the soldering pencils is $10-$30Soldering stationsSoldering station consists of two parts: soldering pencil and a power station. Soldering pencil is attached to a power station. Power station controls temperature of the iron tip in the wide range. It automatically keeps the iron tip at an appropriate temperature. Desired temperature of soldering iron is set with knob on the face plate of power station. Soldering station can be used for most of soldering projects. It can be used for soldering of through-hole components on circuit board as well as for soldering of very fine surface-mount components as small as 0603 and 0805. The price range of the soldering stations is $40-$150.Soldering rework /repair stations systemsSoldering rework/repair systems are complex soldering tools which are mostly used in industry or in the high-volume manufacturing facilities. This soldering systems are the most expensive soldering tools since they usually consist of power station and 4 or 5 hand pieces including soldering iron, hot-air gun, tweezers , vacuum pump which is used for the de-soldering work. The price range of the soldering systems is $250-$2500.Soldering gunsI do not recommend using soldering guns for fine soldering projects on circuit boards.The most popular brand names for soldering irons in the USA are Weller, Pace and Hakko. Aoyue soldering irons are less popular brand name in the United States then Weller or Pace. However, Aoyue soldering irons are much cheaper and they are good combination of quality and price.There is a wide selection of iron tips. Iron tips come in different shapes and sizes. For most soldering projects you can use screwdriver tip 0.062" or 0.032". For fine soldering projects and for soldering of small surface-mount components you can use conical tip 1/16".ConclusionI recommend a temperature controlled 50W soldering station. This soldering station will be excellent tool for most of soldering projects. My top recommendations are:-Weller WESD51 soldering station (digital)- Weller WES51 soldering station (analog)- Hakko FX-888 soldering station- Aoyue 2702A soldering station- Pace ST-25 soldering station
