Hello,
I've seen where clear plastic tubing has been used to line 3-inch PVC pipe with good results. Can anyone point me to a source of these sleeves, and would you use a 4 " sleeve for a 3 " pipe? Thanks.
Thank you both for the suggestions. I am giving the woodland green a try first. About black oxide, that is good to know. I wonder if charcoal would have the same effect if mixed with the green pigment. I have charcoal on hand but not black oxide.
Hello, I'm looking for a deep green pigment that will survive the saponification process and come out dark forest green. The one I tried, Eye Candy Dark Ocean Green, came out gray.
Thanks!
I hope that didnt sound rude. what I mean to say is, saponification will not give a neutral soap directly. It will be slightly basic, maybe pH 8 or so at complete saponification. Then you would adjust the pH down with a bit of acid until you came to pH 7. the soap would still work at pH 7 based...
But you can get a pH 7 in soap. Just not directly. You need to titrate it down a bit after the saponification. Thats why I said it would be easier to do with a liquid soap because it doesn't solidify. You would need to dissolve the bar soap to a liquid before you could adjust the pH down. I...
Can you explain that with chemistry? At a pH of 7, the fatty acids will still be ionized. Its not until the pH drops to around 5 for most alkyl chain carboxylic acids that they become protonated. Unless Im missing something here, it should be possible to have a soap at pH 7 or even 6. I just...
Strictly speaking, pH 7.0 is neutral. Anything above or below is basic or acidic, respectively. Are we talking about bar soap or liquid soap? In theory one could produce a pH 7.0 bar soap directly, but this would require accurate stoichiometric measurements using purified oils. An easier way to...
Ok, here's my first post. Its probably better to say a neutral soap rather than a pH 7 soap. After all, what is a pH 7 soap? Is it pH 7.0? 7.1? 7.2? 6.8? 6.9? Which leads me to ask why it matters that much. But I'm new here, so what do I know? So long as it passes the taste test it's good for me.
