There's this world famous claypot chicken vendor at Kuala lumpur who cooked chicken and rice in a claypot over charcoal.
In this video you can see him using a black sauce. www.TinyURL.com/KLclaypot
Assuming that it's a generic sauce of asian cuisine, can you help me identify it? I want to know what particularly attributes to it's lustre!

Looking at the video, I would say he's using a variety of soy sauces, with one or more being a dark or black variety.

Also from Wikipedia, a picture of the dish with dark soya added:
Update as per the edit to the question:
Dark and black soy sauces tend to have a thicker consistency than 'regular, everyday' soy sauces. (And some are sweetened.) The viscosity allows the sauce to adhere to foods more easily and creates what I refer to as a lovely sheen.
