As a novel glass forming technique created in the middle of the 1st century BC, glassblowing exploited a working property of glass that was previously unknown to glassworkers, inflation, the expansion of a molten blob of glass by introducing a small amount of air to it. That is based on the liquid structure of glass where the atoms are held together by strong chemical bonds in a disordered and random network, therefore molten glass is viscous enough to be blown and gradually hardens as it loses heat.
Answer this question, making sure that the answer is supposed by the text: glass blowing is a technique that dates from roman times?

OPTIONS:
- no
- yes
yes
Som en ny glasformningsteknik skapad i mitten av 1: a århundradet f.Kr. utnyttjade glasblåsning en fungerande egenskap av glas som tidigare var okänd för glasarbetare, inflation, expansionen av en smält glasflik genom att introducera en liten mängd luft till den. Det bygger på glasets flytande struktur där atomerna hålls samman av starka kemiska bindningar i ett oordnat och slumpmässigt nätverk, därför är smält glas visköst nog att blåsas och gradvis hårdnar när det förlorar värme. Svara på den här frågan och se till att svaret antas av texten: Glasblåsning är en teknik som härstammar från romartiden? ALTERNATIV: - nej - ja
As a new glass forming technique created in the middle of the 1st century BC, glass blowing utilized a functioning property of glass previously unknown to glass workers, inflation, the expansion of a molten glass tab by introducing a small amount of air to it. It is based on the liquid structure of the glass where the atoms are held together by strong chemical bonds in a disordered and random network, therefore molten glass is viscous enough to be blown and gradually hardens when it loses heat.
