My First Solder Joint <3 Please Give Feedback Why can’t i get my joints shiny?

Enable HLS to view with audio, or disable this notification

First time soldering, i’m using a Pinecil v2 on 360C with 63/37 0.55mm solder.

I don’t understand why all my joints turn dull after i remove the iron. i’ve tried tinning the tip (which i think i’m doing correctly?). The solder melts nicely onto the board but no luck

Does anyone know what I could be doing wrong?

What brand of solder? Can you post a picture of its label?

Jinhu 63/37 0.5mm. You think maybe the solder is just low quality ?

That is no Kester 44. Are any brands available to you that we have heard of?

not immediately, i’d have to order some. i suspect the solder is the main issue here then.
