Anyone ever see several crystaline-like snowflake grow on the inside of their glass after running several hrs? These things grew in several hrs today, they looked like a snowflake would look like under magnification but these are 2-3 " large. You could see thru them. They wiped off easily with a cloth. Up until now running the stove created the standard haziness with some ash adhering to the inside window. The ash pan was 3/4 full. Blashak.
Don't think think this is any issue, just really interesting.
Anyone ever see this ?
