I have a slowly dwindling pound of Leading Edge Tool Service (LETS') Flux I purchased from Bill Ferguson many years ago.
I use only maybe a tablespoon or two when melting down an 80lb pot of wheelweights as part of my fluxing procedures.
Is this flux any kin to Marvelux? The LETS' stuff seemed to work better & didnt appear to attach itself to my ladles or pot the same as Marvelux (which I no longer use).
Anyone know if the LETS' Flux is still available, or a suitable substitute?
FWIW I do also use pine sawdust / shavings in conjunction with the LETS' when smelting.
Thanks
