Resin is not hash. Hash are those tiny little crystals compressed using heat and/or pressure.

You can't turn redneck moonshine into a fine scotch, just like you can't turn resin into hash.

Resin is the tar that cannabis smoke gives off. It would be the same if you blew tobacco smoke through something long enough. It's what the smoke leaves behind.

You can make resin oil though using Isopropanol Alcohol or Butane. You just soak your pipe in either of that stuff, evaporate the brownish liquid away using heat and what is left, is a gooey resin oil. It's still resin, not hash oil, resin oil.

Keep in mind both of those are highly flammable chemicals, so if you do it, do it outside away from open flames.
