In 1701, a teenager named Johann Friedrich
Bottger, was attracting crowds on the streets of Poland . He was converting two
silver coins into a single gold coin. It was so convincing to the local
population, that the story of the boy reached the King of Poland; Augustus the
Strong. The boy was hauled before the king and locked into a castle and asked
to make gold for the king. Bottger could not meet the kings demand, since his
alchemy, like you guessed, was a well woven trick. The king ordered Bottger to
be hanged. Desperate to save his life, Bottger claimed he knew how to make
porcelain.
Those days, Europe was smitten by
porcelain, which was imported from China . The manufacture was a
Chinese secret and the Europeans were desperate to break it. It was said that
any king who could make porcelain, would wield great power and wealth. King
Augustus had a man called Ehrenfried Walter Von Tschirnhaus, researching on
porcelain; Bottger was made Tschirnhaus’s assistant. Tschirnhaus, had with him
an oven which could reach a temperature of 3000F. This allowed them to melt and
analyse porcelain. Soon the duo discovered the secret; one a white clay called
Kaolin and secondly, they learnt that porcelain glaze and pottery had to be
cooked together and not separately, like it was done elsewhere. The king was
presented with the technique and he dreamed of becoming the most influential
monarch of Europe . This also meant that the
king had to preserve the secret, so now Bottger was locked up under tighter
security, with all dreams of freedom blown away.
But the secret of porcelain leaked and
people all over Europe started making it and
even tinkering and improving it. Mines were opened all over Europe ,
to feed the burgeoning industry of porcelain. In 1780 a mine in Stockholm , on the isle of
Ytterby (pronounced it-er-bee) was opened. Intriguingly the rocks at Ytterby
produced exotic pigments and coloured glazes when processed. Today, anyone
coming across such a property will first suspect lanthanides, but those days,
no one had heard about them. Those days a chemist named Johan Gadolin, had
created quite a name for himself as a geochemist. He lived in Finland , across the Baltic Sea from Stockholm . Amateur
geologist began shipping unusual rocks from Ytterby to him to get his opinion.
Little by little through Gadolins publication, the world began to hear about
this remarkable little quarry. Soon chemist began visiting these rocks, and one
by one new elements started to be discovered. Today six elements in the
Periodic table are named after this little hamlet; more than any person or
place or thing. It was the inspiration for Ytterbium, Yttrium, terbium and
erbium. More elements kept popping out but chemist ran out of alphabets
(‘rbium’, does not sound right). So holmium was chosen after Stockholm
and thulium after the mythic name for Scandinavia .
Today the small town of Ytterby
is a pilgrimage, spot for periodic table fans.
