**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.
