Slightly different here but I do the same as Sunray and Wayne mentioned (from years ago). So I have a stock solution which is what I have made using the instructions in The Laboratory (also previously mentioned) and I have one or two working solution bottles. I carefully pour the liquid from the stock bottle into the working bottle - I stop once I see the bottom layer of calcium hydroxide start to get stirred up. I send the working solution into the class, the stock solution stays in the chem store.
If I decant any, I refill the stock bottle with water, give it a shake and let it settle again before using.

Re: Limewater
I'm trying to set up my lime water still... Does anyone know what size rubber bung with 2 holes fits in the top of a winchester? I have ones that are too big or two small. I did find a cork one that fits (no holes) but none of the measurements match any of the 2 hole rubber bung options I've found online. How hard is it to put your own holes in with a cork borer? I think the cork would disintegrate because the holes would be too close together at the bottom. The diameter of the top of the winchester is about 28mm.
