Cheap molten silver

In your case, there are four ways to control it within 100 yuan.

The simplest method 1:

I told the first floor to find a gas welding processing point.

Simple method 2:

If you have a gas tank, go to the refrigeration equipment store and buy a gas welding torch (30-50 yuan).

Composite method 3:

This method is laborious, but it saves money. I used it when I was a kid. It can dissolve silver, but it needs a large lung capacity. You should prepare an alcohol lamp (kerosene lamp, candle is ok) and a pure copper oil refill, and the handwriting should be thick (preferably used up). Find a thin steel wire to poke out the beads of the refill from the back (the new one will produce a lot of oil and needs cleaning). Light the alcohol lamp, put the oil refill at the end of the smallest bead near the outer flame, and let the salamander barbecue the silverware, which can melt a silverware the size of a peanut.

The most complicate method 4:

This method is an upgraded version of Method 3. In addition, you should prepare a pump, a bicycle inner tube, (or a leather tiger, but it's expensive and hard to buy), a hose, a short piece of hard pipe and a strong thin rope (fine wire is also ok). Cut the inner tube to about 50 cm (note: there must be a sound valve), and tie one end with a rope to prevent air leakage. The other end is tied with a hard pipe, which is connected with one end of a hose, and the other end of the hose is connected with an oil filler. When the equipment is ready, start melting silver: clamp the air pump nozzle on the valve of the inner tube to inflate it, and inflate the inner tube (don't use too much force, or it will be dangerous! ), use method 3 at the end of refueling.
