yep will do, thanks!

So linotas, was your solution A clear?
I'm trying another batch but it's not looking good!
My solution B is just 500mls 3% Hydrogen Peroxide and 500mls distilled water

Hi all, I am making Solution A for the Iodine Clock Reaction following this recipe: 0.6g Starch 4.1g Sodium Acetate 30mls Acetic Acid 50g Potassium Iodide 4.7g Sodium Thiosulfate The solution is very cloudy. My question is, has anyone made this particular one and if so how long should it take to go ...

We had two 3-D printers, but they have just been reassigned to the library.
They weren't being used in science, they do take a long time to produce a figure, so it's not practical to attempt a class set of any figures.
I don't recall what brands they were though.

Mmmmmmmmmmmmmm.........................did you have to bring that up?????? I been busy!

Yes Merilyn, I have your blank!!!! Ha ha

At the TPL day I attended recently, at which Alan was a presenter, he basically said do your stocktake however you wish, on chemwatch, on a spread sheet, with pen and paper, there are no hard and fast rules according to him! Mine is done on chemwatch, I'm not game to check yet, I'll deal with that l...

Yep, that's what we in the public system have to follow..................

There won't be an updated version of CSIS until, at least, late 2018......my understanding after attending a professional learning session with Alan Smith week 1 this term.................

I hear you vickir! I've been in science for 3 years, also with no training, and none of the office ladies have ever been to my prep rooms......I don't think they even know where we are!! When I first started here, one of the office ladies said to me she doesn't go out into that "hostile environ...

We are definitely the forgotten SAS staff vickir! The kitchen lady, the library lady and the office staff are all getting some training in the LMBR.....not me..... Ah well, I'll just continue to live under the stairs, haha!

We use tea leaves here too.

The SAM is my supervisor here. We were given the forms to fill out and pretty much left to our own devices...... Not a whole lot of support here, and if I ask I feel like I'm being a nuisance! So I wrote what I thought was relevant for me..........

Maybe we should all know the company's name.......if they are acting illegally I don't want to use them!!

There is none here..........that I have come across anyway, there are still corners of the storeroom I haven't delved into yet haha! It does seem though that glass wool is not a regularly used item.

Ha Ha bigmack! I'm glad I was able to solve a query for you!!
I did a bit of googling too and filtering wasn't mentioned anywhere else. So we'll see what happens!!
Thanks for the replies, people

Hi all,

I need to make up some potassium permanganate, I have my printout for solutions that I got off this site and it says to "filter through glass wool".
Any other way of filtering it???????????????

Guidance will be much appreciated
