How can one blow/work with borosilicate glass to a container of precise dimensions? I am a poor graduate student who is wishing to make a container out of borosilicate. I need pretty tight control over the final shape. Is it possible to work a piece of glass to a specific spec by hand?

I want to make a perfect hollow cylinder that will serve as a tank wall, for starters. I have access to a craft center through my school and willingness to learn. I was going to sign up for a class but if this is a pipe dream I will find another means. 

UPDATE

I found a website that has some of the techniques I wish to employ see the following link. I am still wondering how well one can control some of the dimensions. I would be shooting for pretty uniform cross sections. Also they all start with the glass in a tube-like geometry already. How do you even make that from scratch?
Borosilicate also goes by the brand name Pyrex. If you perform a search for "borosilicate glass cylinder" you will find some sources of various sizes of tubing.

If you have access to a sufficient powerful heat source, you can heat the tubing and force it to close. 

A quick bit of research shows the working temperature to be 1245°C, attainable by MAPP gas torches at the consumer level. If you know someone who does gas welding, oxy-acetylene torches will reach the necessary temperatures at a lower cost overall.
