Subject:
lichen growth
I'm greatly enjoying the vast and disparate knowledge being demonstrated
on this site. As coincidence would have it I had just read an article in
the re-incarnated publication Traditional Masonry Vol.1, Issue 1, Fall
2006. It had a great description of encouraging lichen growth on
Stonehenge after some graffiti was air brushed off (with a fine
aluminium oxide crystal dust ). After the paint was cleaned off the
result was the offending message was now a larger version of the
original but in perfectly clean stone, not paint.
To get the lichen growth going they devised a "sh*t cocktail" composed
of chicken, pig and cow dung mixed in with sour milk. No joke. Now
picture doctorate holding academics reaching into buckets and flinging
sh*t at Stonehenge--pretty funny. They found that throwing it encouraged
a more natural growth of lichen rather than painting the mix on...I'll
stop now...hope you all aren't eating...
Cheers,
Will
