Was looking through the Detroit Stove Works 1911 catalog. For a few stoves it says for the fuel type "For Soft Coal, Slack and Siftings."

Just what I found online I ain't no expert. Also appears to have been popular 100 years ago.

Excellent.

From the link you provided "Slack is the dust particles that drop from the automated screener which we bag".
I am supposing that Siftings is probably some variate of Slack then.?

"Knots" as in grasses knotted?
"Chips" as in cow chips or buffalo chips?
"Shavings" as in wood shavings?
