I have not tried melting any yet but odds are you have to go much higher and let salt come up to temperature. Heat treating salts may have additives to lower temperature of melting. Off to research this more Nitrate-Nitrate eutectic
John the Potassium Chloride I use for heat treating ( which is 99 % pure ) no additives, melts at 772-776 deg C 1423- 1428 deg F. I don't believe most furnaces are more accurate than that.
I got it to melt at 1570F I’m just going to assume that the melting temp is different and both my thermocouples are accurate. I got aluminum to melt at 1250F so to too far of it’s melting point.
Well I finally finished the filet knife after putting it off due to Christmas orders. Flexes very well and springs back without a problem. AEB-L austenitized at 1975, plate quench, directly to my freezer for about 10 mins (I find this reduces the LN boiling off as much compared to slightly warm after quench) then to LN overnight. Tempered at 350F, I’d guess it’s around 62Hrc based on files. The handle is bocote and box elder,with maple and black fiber liners
Thanks guys!! Yeah now that you mention it, it does kind of look like bone. Once I polished the wood up the shiny lighter stripes showed up, I really had no idea they were there
