The batch that I made for testing was 3ozs each of metabisulfate and thiosulfate in 10ozs of water. DeeAnna gives a better breakdown of the math in her post.
I only used distilled water for diluting the ingredients.
If you want to warm the water up to around 100°F it will help the metabisulfate dissolve faster and thiosulfate will dissolve quickly at any temperature.
Okay I looked back at DeeAnna's post #88 on page 5 of this thread (Yesterday I kept looking for it, but for some reason it eluded me.) Okay, then the ratio was: 3:3:10, so the percentages come out to 18.75% each of the Na-Metatsulfite & Na-Thiosulfate and 52.5% distilled water.
18.75% or 3 parts sodium metabisulfite
18.75% or 3 parts sodium thiosulfate
62.5% or 10 parts distilled water
I will heat distilled water to 100° F first for faster dilution
Thank you, Todd.
Can you clarify for me regarding questions #4 & #5 I had? I am still a bit unsure which you used &/or why. I was hoping for all the information in one summary because searching back and forth through all 6 pages (so far) of this thread is getting cumbersome and I keep losing track of things. I don't want to make a mistake that I have to then toss out or try to re-batch. I'm sorry to put you on the spot, it's just how my mind works.
4. What is your chosen dilution for sodium metabisulfite alone? And why?
I think you tried 2 different dilutions. (Your Post #34 - was that about sodium metabisulfite? 0.25 ounces to 1 ounce water? 25% dilution?) (Your Post #36 50% solution? But you also mixed a 60% solution; did you ever try it?) In your post #41, you said you would make a 30% solution) So I'm wondering which dilution you have settled on as best for only sodium metasulfite.
5. What is your chosen dilution for sodium thiosulfate alone?
You settled on a 25% solution per your post #67. Why? Was that based on trying a 50% solution and seeing no difference in the results between the two? I may just go with that because of the OP's link to the DIY VS.
