Well I got some nice charcoal, used about four golf ball sized pieces, broke the coke into dice sized lumps and covered the small charcoal fire!
And they glowed up a treat. A joy to work with, especially as up until now I have been using BBQ charcoal.
Far less crap on my work piece and a way more even manageable heat plus hardly any clinky crud. And of course smaller grains of fuel that i can push my work into. JOY
Thanks to you r advice todays few hours at the forge resulted in two nice stick tang knife blanks, ready for a polish grind heat treat etc.
Just to add, I'm not used to such an intensity of heat, I left my first piece of steel in too long (bit of 4x4 suspension coil) and the ned melted away and it started to burn, sparkling.
A good omen!
Im now a fan of coke, thats for sure!
