To keep things from getting lost ...
remember that the very first compasses were NOT closed,
they consisted of a bowl of water with a load-stone (fastened to a piece of wood) floating - even earlier one just had a piece of string tied to the lode stone.

As compass needle is a small and thin magnetized needle, it can get affected by the air and dust setting on it.

In general, open. Doors may be closed when fire has burned down. Even tempered glass may shatter during very hot burns.
It will crack and break and maybe the heated gasses inside will make it explode.
You build a charge The wool cloth is very weak in holding electrons so when you rub it with the ebonite rod the electrons transfer onto the rod. The rod is negativly charged (assuming that the rod was neutrally charged). The wool becomes positivly charged (assuming that the wool was neutrally charged)
A lensatic compass is a compass with a magnifying glass on the sight which makes it easier to view the needle. These types of compasses are frequently used in the military.

A vial.
Scratching the inside of the vessel with a glass rod provides rough surfaces for crystals to form and grow. These rough surfaces serve as nucleation sites for the dissolved compound, promoting the formation of new crystals. This process is known as "seeding" and helps induce recrystallization by creating a template for crystal growth.
Yes, glass can be cut with a radius by using a special glass cutter or a wet saw with a diamond blade. It is important to use proper safety precautions and techniques to avoid chipping or cracking the glass.
Dominion Glass Co. had two different plants in Toronto, they both closed in 1925.
