Interesting Stamps of Iceland  with 
Eyjafjallajökull  Volcanic Ash Embedded

Iceland  had  issued three stamps last year in 2010 , that have pieces of volcanic ash embedded in the designs.

The stamps are inscribed (from left to right) 'Local Letter 50g' (75kr), 'Letters to Europe 50g' (165kr), 'Letters to Other Countries' (220kr)

All three stamps are silkscreen printed with very fine-grained trachyandesite ash which fell at Eyjafjallajokull on April 17, 2010  a little more than three months before the stamps' issue date of July 22,  2010. The three stamps have artistic rendering of the fissure and central vent phases of the eruption.

Iceland is not the first nation to implant things in their postage. Other items, including soil, rock, meteorite dust and even jewels, also have been embedded in stamps.

In 2002, pieces of the Rock of Gibraltar were incorporated into four stamps put out by the Gibraltar Philatelic Bureau. In 2008, Aland, an island archipelago in the Baltic Sea, burned pieces of red granite onto a stamp by a heating process known as thermography. And soil from a school for children with special needs was silkscreened onto a set of 10 South African stamps issued in January 2010.
