I know its late to reply here, but here is my advise on mixing ferric chloride
Thumb Rule: Always mix powder in water , never pour water on chemical ,
Mix Ferric chloride in open area,
Always wear mask and gloves
RATIO
We are Mixing 55 pounds of bag in 35 ltr of water
We are doing etching through Photoetching machine made by etchcut,India, capacity of tank is 240 ltr
so we mix around 6 bags with 210 ltr of water will make it almost 240 ltr
By the way we do all type of Iron cuttings of sheets, generally we make 3d models from last 10 years using this wonderful machine here is the ref pic enclosed of 3d model
