Review: Ferris sulfates - Great product
Review: Great for making ferrous sulfate developer - I bought this to make ferrous sulfate developer for wet-plate tintype photography. For that, it works great! Using this ferrous sulfate powder, I'm able to make that developer far, far cheaper than it would cost for a pre-mixed solution. 20 grams of this dissolves very well in 500ml of water. The packaging is easily manipulated while wearing rubber gloves but holds it's contents firmly. I've just happily ordered my second bottle.

**Q: I want so soak my bee wood pine boxes in this for treatment.  Any idea how many ounces i would use in 5 gallon bucket? --thanks**
A: 5 gallons would require about 1 pound of ferrous sulfate, it acts both as a colorant (aging solution) and a preservative.  Test on a sample first since, the amount of  lignin and pine tar in the wood make the effect quite variable.

**Q: Has anyone attempted to make Gall ink with this?**
A: This is the "long term" component of Gall ink, I was unable to obtain Oak Galls so I tried some substitutes, I made one batch with Tannic Acid, - it produced a brownish ink that turned dark over time and another using sawdust extracted with Ferric Chloride this worked much better starting out black ad turning brown / red over time.

### ⭐ Not ACS Grade!
*by E***P on September 20, 2025*

This material is highly contaminated. There's no way it's ACS grade. When I dissolved it in distilled water, there were black particulates floating, and the solution was very, very cloudy. It had to be filtered to clarify it. This seems like agricultural, feed-grade material. You can buy that for much less.
