Today, Icelandic Post published 3 new stamps, which are unique.
All the stamps are silkscreen printed with very fine-grained trachyandesite ash (3 microns (μm) or less) which fell at Eyjafjallajökull April 17th 2010. The trachyandesite magma has ca. 60% silica content and comes from a depth of 7 km with a temperature of more than 1100°C when it reaches the glacial ice.
If any of you magicians are stamp collectors, feel free to send me a PM, and I can send you a letter with the Volcanic Ash stamps on them.
All the best,
