How to make solder paste flux and liquid flux

Many friends know that flux is very important when soldering.
Today we are only talking about flux and not how to solder is correct.
Fluxes include rosin, paste flux, liquid flux, etc.
As far as I know, the main component of paste flux and liquid flux is rosin.
And rosin is the most basic and practical flux.
But in the process of use, because the rosin is solid, sometimes it is not convenient to use.
Today I will share with you how to make rosin into a liquid or paste flux.
It’s actually very simple, just dissolve the rosin in alcohol.
Try to use higher concentration alcohol, such as 95% medical alcohol
Industrial alcohol can also.
However, industrial alcohol contains a small amount of methanol, aldehydes, organic acids, etc.
Harmful to humans, so it's best not to use industrial alcohol.
If a large piece of rosin is best made into small pieces or powder, it will dissolve faster.
Alcohol will evaporate. When you think it is too thick, just add some alcohol to it.
