This exciting new product makes gold refining much easier and more comfortable. After over a decade in development by Shor’s R&D department, this powdered precipitant has been perfected to meet all of the characteristics you've been asking for, including:
Unlimited shelf life
Gold precipitates as heavy mud, commonly referred to as “sponge,” making filtering unnecessary.
Precipitates pure gold from all chloride-based solutions, including: saltwater, nitric acid-based aqua regia, SubZero based aqua regia and all other chloride-based solutions.
Very selective; precipitates only gold, of at least 99.95+% purity.
Over a decade in development by Shor R&D. Field tested by hundreds of users.
