Provan Gasworks

Provan Gasworks was bound by Germiston, Blackhill, the Monkland canal and Blochairn. What remains today (from online aerial mapping) seems largely to be the course of nature and two rather large gasometers which effectively welcome you to Glasgow as you drive in from the East on the M8 motorway.
But what was there before the 21st century?
What wider purpose did the area serve?
How many people were employed?
Were they from the immediate areas of Germiston, the Garngad and Blackhill?
Was it only as a producer of town gas, or was there a wider purpose?
...and if it was a producer of town gas, is this what led to the area being largely green/brownspace?

I am keen to know?
