How to melt and cast silver powder into silver ingots?

It should be possible, but it will take a long time, because I have tried to melt the salt by heating the ceramic crucible with an alcohol blowtorch before. In this experiment, the melting point of salt is 80 1 degree, which takes a long time to melt. Moreover, the melting point of silver in ceramic crucible is higher and the heat transfer is faster, while the temperature of alcohol blowtorch is about 1250 degrees. It is really not easy to melt it through a graphite crucible. If your method doesn't work, you can try to put the graphite crucible into a coal stove to heat it, or blow it down from the graphite crucible with a flame such as a gas lamp to heat it. It should be possible. Also, if you put it in a coal stove for heating, the coal stove must be blown by a fan to raise the temperature. If it is honeycomb coal, dig out the middle part of the coal and put the graphite crucible in it. That's it. If not, please reply here.
