I think it's a recipe like:
55% petroleum jelly
40% rosin
5% alcohol
because Vaseline is a rosin thinner ...

Welcome to the flux party, @Ubuntuwi

Have you tried making the recipe you suggested?

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.
