Shellac Production

I was wondering how shellac is produced (ie how the bugs are reared, the resin harvested and refined, etc).

If you're interested, here's a very informative video I found on YouTube:

The quality is not always very good, but it answered all my questions

Thank you, that was very interesting. I did not realize how much handwork was involved.
