Low level flaming swords?

[Weirdo]

One of my players would like a flaming sword for their ranger for "In Pale Mountain's Shadow." Magic weapons aren't available to 4th level characters, but is there a way to get a similar effect, possibly with a consumable item?

A Flaming Rune is 9th level, so no go there...
There should be a low-level alchemical or magical item which grants one or more strikes worth of extra elemental damage... but I cannot find one. Seems like something that could/should be added to the final Rulebook. But that doesn't help your player much I'm afraid.

Personally I think low-level alchemical items that you applied to a weapon (like silversheen) to cause it to deal extra elemental damage, or give off light, or whatever would be really appropriate and useful for all sorts of alchemists.

Yup, those would be great. A trinket that adds elemental damage to a single attack would also be neat. I would normally homebrew one or both, but I'm trying to playtest as-written.

Be a dragon totem barbarian seems to be the only option I can find at lvl 4. Doesn't help your ranger much though.
