I think a third of the weight can not be bad. So you have 1 part rosin, 1part IPA or other alcohol and 1 part petroleum jelly. --- End quote --- I think it's a recipe like: 55% petroleum jelly 40% rosin 5% alcohol because Vaseline is a rosin thinner ...

SilverSolder yes, I tried to make the recipe that I suggested!: in a few days I will publish some tricks, which I learned immediately, in the meantime I tell you: you have to mix the rosin powder with vaseline, (cold), then using a stove electric, put everything in an earthenware pot, bring the temperature to 130 ° celsius, (everything melts) mix with a piece of wood; always turn ... when you see that the rosin wants to separate from the petroleum jelly ... spray the alcohol, isopropilic. (at this point the temperature should be around 80 ° celsius, and hot alcohol is soluble with rosin, but also with petroleum jelly, all this giving an inseparable mixture). continue to mix until cool. |
