## Questions & Answers

**Q: Is this ideal for jewelry making, ie, placing 2 microscope slides together, foiled, then the application of solder?**
A: It will stick to foil that is not coated with anything

**Q: Does the flux residue require cleaning? Or is it no clean?**
A: It can be a little messy, but I don't typically clean it.  For hobby projects I leave it there.  For professional projects it would be good to clean it.

**Q: can this fix jewelry?**
A: Better to find silver solder.  This is for electronic stuff.

**Q: What is the difference between small and large?**
A: small solder is about 1/16th of   an inch in radius(width) and large solder is approx 1/8th inch in radius(width).  Small is normally used for light solder jobs Ie:  circuit boards,etc.  Large is used for heavier jobs that  require more solder.   Hope it helped.
