This is for economics and for tradition.
Original container type consisted of ceramics, glass, metal and treated wood and leather. The last two were difficult to use and make water (solvent) tight. Metals reacted often. Ceramics needed to be glazed because they were porous.
Only glass was nonreactive, non-porous, and water tight. In addition it could be transparent, so keeping it clean was less of a problem. New forms (like Pyrex and Kimex) are also tempered so that they can withstand changes in temperature.
Ground glass joints are also easy to make and relatively leak free. Compared to other materials with similar properties, glass is in expensive.
Recent changes in some labware to plastics is for measuring devices and storage containers. They are less breakable than glass and so can be used for longer periods before replacement.

Glass does not react with most chemicals. Or interact with chemical reactions. And of course, the Pyrex benefit is quite important.

Because glass does not react with most of the materials used in chemistry experiments. Fo those chemicals that would react with glass, other materials have to be used.

1. inertness- doesnt react with most of the chemicals
2. transparent- allows the observer to see what is going on
3. poor heat conductance- abrupt increase in temperature is not desired
4. comparatively cheap
5. no adsorption- glass cannot adsorb gases or liquids (adsorption may decrease the yield)
6. environment friendly
7. use and through in certain cases

Glass is one of the most chemically inert substances on earth. Very few acids or bases can affect it, and it doesn't catalyze any compounds. It's also easy to clean and relatively cheap.

So u can see the reaction? Plus i dont think it reacts with anything...A bit funny if u conducted an experiment on a surface that exploded lol...

glass doesn't chemically react with most reagents. it used to be done in copper apparati that can't withstand acidic conditions. if your apparati doesn't react that means you have a better chance of getting the product you want

glass is highly unractive i think flourine is the only thing to have a big impact on it. and it has a high melting point, higher than pyrex.
most likely it is just tradition and glass is probably cheaper.

example when making fulimated mercury a metal pan will cause picric acid to build up which causes it to detonate

I think because most acids can't effect glass and you can see what happen in there (color, rate of change in color, bubbles and ...)
