Hi
Jennifer,
you have
all you need for basic soldering. As A pickle I prefer the really harmless
pickle from 10% Alum-salt + 90% water, working temperature about 50 degree
Celsius.
You can
solder solder copper with silver solder also. The disadvantage is, that the
solder seam looks silver-colored and is to see very clear. The advantage from
silver solder on copper is, that the silver solder flows more easy than the
copper solder.
If you use
soldering-paste, you do not need no flux. Important is only, that the areas
where the both pieces are in contact are really clean. You need flux only, if
you are with silver-soldering-sheet or
soldering wire working.
The terms
soft, medium or hard of the silver solder is only a description of the working
temperature. Soft means a low temperature, hard a higher melting temperature.
The soldering seams have all the same solidity, equal if you solder with easy
solder or extra hard solder.
Apart from that, soldering is just a matter of
practice. Very important is, that the torch is not too small. If you do not get
enough heat, it is impossible to make a good soldering job.
