Can electricity pass through glass ?

Hi.
Given enough voltage, will energized things on sides of ~3mm plain glass spark into/across to the other side ? Like plates of a capacitor arcing ?

An insulator is essentially a dielectric... two plates on either side of a dielectric form a capacitor. AC passes through a capacitor. So even those rubber sole shoes won't save you if the voltage is large enough and it's AC. Even if the DC is high enough it can punch through the dielectric.
