Fang Zhen picked up a square glass bottle from in front of him and got to work.
He had bought these glass bottles from a nearby scrap yard.
Making a Molotov Cocktail might seem simple, but there are many technical details to consider. The choice of bottle is one of them.
Many glass bottles on the market are made of soda-lime glass. This type of glass is sturdy, durable, and somewhat elastic. While it's a good choice for liquor bottles, it's not ideal for a firebomb.
Some glass medicine vials are even made of borosilicate glass, which is tougher and more resistant to corrosion and heat.
Since Fang Zhen was making Molotov Cocktails, he obviously had to avoid these two materials.
It would be pretty embarrassing to throw a firebomb only for it not to shatter because the glass was too high-quality.
He chose liquor bottles made of plain glass—ordinary glass with no other elements mixed in, which made it more fragile.
Fang Zhen also deliberately chose square-shaped bottles.
