MAKING BLOOD BANK BOTTLES - SOUND

The video explains the process of creating a glass blood bank bottle. It starts with the formation of glass from furnace heat, followed by shaping the molten glass into a bottle. The process includes blowing the glass, shaping the neck, and ensuring the bottle is strong enough to safely store blood. The final steps involve cutting away excess glass, grinding rough edges, and inspecting the bottle for flaws, ensuring it is a safe deposit for human energy.

What is the initial form of glass before it is shaped into a blood bank bottle?

• A powder

• A molten bubble

• A thin sheet

• A solid block

What is the purpose of constantly turning the glass during the shaping process?

• To make it transparent

• To add color

• To prevent it from falling or breaking

• To cool it down

What is the final step in ensuring the bottle's neck is strong enough?

• Cooling it rapidly

• Adding a rim

• Heating it again

• Painting it

How is the superfluous top of the bottle removed?

• By breaking it off

• By sanding it down

• By cutting it with a knife

• By melting it with a blue jet of gas

What is done to the rough edges of the bottle after inspection?

• They are painted

• They are polished with a cloth
