cristalli di sale di rame

Questo vetro presenta innumerevoli pagliuzze dorate, composte da minutissimi cristalli di sale di rame.
Il segreto della composizione di questo composto, detenuto nei secoli da pochi maestri vetrai, sta nell'aggiungere, dopo la fusione dei cristalli di sale di rama con il vetro, appropriate quantità di materie prime come ferro, silicio metallico e carbone.
Con un lento processo di raffreddamento del vetro fuso, il rame metallico viene separato dal vetro di base e si vengono a formare cristalli di rame rendono unica tutta la qualità del vetro.

Aventurine glass was produced initially by the Miotti family, in the 17th century, its origins perhaps dictated by the name they gave it, which means “lucky” or “by chance’ and was discovered when workers accidentally contaminated a batch of glass with copper filings.
Upon starting work with the glass Miotti noticed the sparkle throughout the glass, and so it was born.
It remained a family secret until the widow of one unwittingly revealed the secret almost 200 years later.
Also known as Stellaria, or goldstone, this stunning technique is created by adding copper, or copper sulphate, to produce a rich brown colour.
