I know cooksons and other suppliers sell borax cones, but I'm waiting for an order (including a Borax cone).
I've hunted for Borax in chemists, DIY shops etc, yet nobody seems to know what it is I'm talking about.
However, there has been a change recently (some EU directive) so they've classed it as hazardous(?), which is probably why it's so hard to get hold of now.
I've managed to buy Borax substitute (by Dri-Pak), but I'm wondering if it's still acceptable for use as a flux (I don't understand the chemical differences)? Otherwise, I'll save it for cleaning
