Keith ... I've just uploaded this photo ...
(http://www.biopowered.co.uk/w/images/1/13/Emulsion_from_on_the_bottom_of_wash_barrel_1.JPG)
Of an emulsion formed at the bottom of my wash barrel. Might be of some use on the Acid wash page to show what we're trying to avoid.
I've added it to the water washing page and it should come in useful when the "Emulsions" page gets written.
-
Is that emulsion or HMPE's Julian? just looking at the residue around the sides also.
-
I would say Hmpe's, I get the same now the temp is dropping, I will gladly stand corrected if i'm wrong though. Hoping that the acid wash method is going to cure my Bio of this.
Looking at your description on the Wiki page it would seem I am going to be wrong !

Thanks Julian,me and Jules are making a start so all pics/suggestions welcome

Definitely an emulsion, been getting to a greater or lesser extent most of the summer.
Splits to bio and water when heated.
-
I started on some of the text for the page today. I didn't get far but it's started.
-
I had a couple of hours to play on the computer this evening so have done a lot more on the Wiki page - what do you guys think so far?
I have refreshed the Wiki home page so the titrated method now shows up in the processing methods section

Okay I think I got the wrong end of the stick at the beginning of the thread, duh !
so is heat all that's needed to split an emulsion ?

Good work Jules - learned a few things from that page I didn't already know which is the objective after all :)

Thanks for the positive comments. I am off to help JulianF with some building work shortly and wont be back till tomorrow when I will try to do some more.
I intend to put two worked examples on there - Keiths using Vinegar and mine using H2SO4.

Oh dear, we've seen pictures of the last time you did some building work at his place.
Great wright up mate, I did spot a couple of spelling mistakes but I'm a fine one to talk.
This bit doesn't read quite right to me,
"An indicator needs to be used which will clearly show and basic to acidic change around the neutral point. A suitable indicator which works very well is BromoThymol Blue, the colours of which are shown on the right in acidic (yellow), neutral (green) and basic (blue) conditions. "
surly it should read "clearly show the bass to acidic change", or is it "alkali to acidic" I'm not sure which is best.
I know it's only knit picking but it would be nice to get it reading right.

not wanting to sound like alecr over on VOD, but the word is BASE. BASS is the name of a brewery and also the term for a low frequency signal.

Not wanting to sound like photoman290 on biopowered ... there's no such member as "alecr" on the VOD.

And a fish,you should know that living where you do ;D
-
What it should say is Basic to Acidic (Basic being the correct term as opposed to Alkaline). I will amend it now.

I can't help but see the irony in you making a spelling mistake in that sentence.
I think you mean 'Great write up mate.....'

bass? we cant afford to eat bass down here. that for the visitors. mackerel for the locals.

That's a new one on me ... so acidic is to basic as acid is to base, then?
-
Indeed so - as written here among other articles.... http://www.elmhurst.edu/~chm/vchembook/184ph.html
-
Not disputing the correctness of it's use, but as many will be struggling with the whole chemistry thing (as I do!), would it be better to use terminology that's in common usage? Just one less thing that Muppets like me wouldn't have to work out!
-
Funnily enough, I originally wrote Alkaline when writing the article then corrected it because I though that, if I didn't somebody would point out that it was not the right word.
To cover all bases (excuse the pun) I have now changed it to say Basic (Alkaline) conditons.

Sometimes I can be subtle, other times I just can't spell, but you know that by now.
The important bit is it makes sense to the common man.
