# Do glass beads show any piezoelectric property?

Do glass beads show any piezoelectric property? Since glass beads are mostly made out of SiO2 which is piezoelectric, will it show any piezoelectric property?

On the other hand it is possible to manufacture a piezoelectric glass, e.g. from a compound related to strontium titanate (link to journal article) by orienting the molecular dipoles during the glass transition. This might be possible for SiO$$_2$$ as well but is not the case for glass beads that have not undergone any special treatment.
