Lately have been noticing that I have had an awful large amount of black coals in the morning.... I figured my wood was seasoned enough as it was cut split and stacked for over a year single rows with plenty of sun and wind. Checked with moisture meter and some read 28% on a fresh split side!!... I am going to have to burn it as its all I have... Question is, I cleaned my glass last week and it is still absolutely spotless...... If the wood was " unseasoned " ..... I would figure I would b getting some black or discolorec glass.... I'm not even getting moisture or hissing from the wood...
