Where can one obtain fluxless, lead-free solder paste?

Prefer tin or other low-toxicity, low-melt-temp substances.

Also interested in Homemade paste.

This product's vendor claims it's fluxless. How can I be sure?

Fluxless? Does such a thing exist? Would you want such a thing to even exist? The flux stops the solder beads which have low-volume and high surface area from oxidizing instantly rendering it unusable. Also stops it from becoming airborne.

The paste in your link is not flux free.

It's also not lead-free either, it's clearly described as leaded solder, and even gives the lead/tin ratio further down in the specs.

As others have said though, why flux free? - what's the point of solder that won't solder?.
