It must have been 7 years ago or more after a Xmas that we 
discovered how attractive/absorbent HM coatings are for 
candle and open fire fumes. What was a near white German 
Etching print became creamy, more to brown than yellow, in 
10 days time. Near the fire place and with lots of candles 
but nevertheless.
