Thank you guys for the kind words.
Butcher - The camera i used for the underwater shot is GoPro, it is an "extreme" camera as they call it and it has a casing that is designed to be water and shock proof.
Göran - Thanks for the embedding tip!
GotTheBug and Irons - Yes, i totally agree. The blanket is indeed more susceptible to degrade by flux fumes. There are "spay on" refractory clay/cement and also silicate based nano-suspensions to rigidize and protect it. I hear a good rigidizer makes it hard as a brick, you position the blanket in any shape you need and after the first heating run it sets, however i never tried it.
Lou - Thanks, i actually am using a water pump inside the bucket to circulate the water around, but i couldn't get a clear shot while the water was spinning around. I have seen it done similarly in Umicore, where they had a huge water tank and the water was swirling like crazy. the tank sits under the vertical "tapping" hole which is basically a multple holes grphite die, about 10-15 holes.

Alternatively, you can make nice shot by putting a wood board or piece of graphite and pouring onto that.
I think i have an idea, but could you elaborate more? how should it work?
Anyways, the silver/gold shot are later screend for re-cast small and large rejects, Here below is a screening kit i'm using:
For size reference, each tile on the floor is 1ft long
