Hi,
New to this forum and new to blacksmithing,
Nice site appreciate the work you did and do.
If I may ask a question - Is there something like borax that can wash out the gunk from say cable rope in the same way like borax. Did use sand, clay and also WD40 but my understanding so far is that they exclude air only not clean out the impurities. On my third forge weld attempt had great success with WD40 as a flux. Here is a pic. BTW are those decarb lines or delamination cracks. Would help me a lot to know.
Thanks again,
David.
