'chimney'

ETYMOLOGY

[Why /oj/? Not borrowed from Silesian, apparently; no sign of ✱✱komin in Schlesisches Wörterbuch. Old Polish must have had a long /oː/ for some reason.]
Middle Polish kȯmin 'chimney; hearth, stove', apparently borrowed from MHG in the 14th c.
{Boryś 246; Brückner 250; Geller and Gajek, 2023: 55}
Beider suggests the etymon could also be Old Czech komín, also borrowed from MHG. The root vowel was lengthened in an open syllable to produce protovowel O₂₃ (either in Y or in a German dialect from which Y borrowed the word).
{Beider 2015: 349, 454}
MHG kamîn (probably stressed on the first syllable kámîn) 'fireplace', ENHG kamin 'chimney', from Romance and Latin camīnus 'fireplace', from Greek κάμινος 'melting furnace'.
Lexer cites once MHG komîn from a 15th c. legal document from Zurich in Grimm's Weisthümer (4: 302).
{DW¹ 11: 100; EWD "kamin"; Lexer 1: 1504}
The idiom פֿאַרשרײַב עס מיט אַ קויל אין קוימען 'record it with coal in a chimney (i.e., it's a lost cause - you can forget about it)' appears to be a calque of Polish zapisz sobie w kominie 'record it in a chimney'.
