I haven't used a coke or coal forge before, just propane and induction. At close look it seems the clinker has a look similar to putting flux on your work piece for forge welding. Flux similarly forms a glassy mess when I am smelting. I am wondering if it is a similar effect especially since you mentioned silica. I appreciate the close-up look at it. I have considered in the past building or modifying a smaller hand crank rivet forge just for quick localized heats on small or thin material. This information gets me closer to moving in that direction.
A coke forge is well worth building - it is easy, all you need is a blower and some coke. You'll find a coke forge is hotter than a gas forge, and as a result you have to keep a close eye on your work piece to prevent it from burning.
Forge On
Keep Forge lit.
Keep Making.
God bless.
