Praying to the rust fairy.

Today I discovered that ferrous sulphate is nowhere to be found in Fredericton. Garden stores, hardware stores, grocery stores, pharmacies; all came up empty. My only hit was in the “online only” section of Home Depot website. No time to be ordering away, the bridge piece needs finishing in the next week.

So for experiment #1 I settled for a big ol’ piece of chain, which unfortunately is galvanized. I put in the fabric, weighed it down with the chain, and poured in about 2 L of vinegar.

It immediately began to fizz. I suspect it is the zinc coating coming off. At any rate, I took it out to the shed for safety’s sake. Who knows what all is toxic these days. Don’t want to be breathing anything in.

When I was at the pharmacy I looked for iron sulphate but found only iron bisglycinate. I bought a bottle anyhow.

So for experiment #2, I followed the instructions here but with the whole bottle of iron supplement. It really seemed to have no effect at all (fabric was already cream-tinted). However you are supposed to let it dry before washing out so maybe if will oxidize overnight.

For Experiment #3, I grabbed the bucket of iron tablets/4 L of water that I had used above and threw in about a cup of vinegar. I put some fabric in, weighed it down with a wine bottle, and put it in the shed.

This was maybe an hour after Experiment #1 got started, and check out the foaming action now! Neato!

It looks like most of the shiny coating has come off the chain, so hopefully the next step is rust. Or it could all go horribly wrong and I’ll have to suck it up and use synthetics.

Cross your fingers for me!
