We have used the new soft leaves of hydrangeas too. Although that may be a challenge this time of the year in some areas as they are deciduous!!

Yes J its stupid!!! Now I've discovered this setting though it has made life a little easier!

So are you buying it from the Nathan mentioned in the article?

Sorry I can't help, However I have always bought the premade solutions and never made it from a solid! We use this for everything you just mentioned. Because you only use a drop or 2 every time its not overly expensive! I have bought it once in 10years!

Found it under Sulfuric acid 2m solution. When the list of chemical comes up and you can't find what you are after try clicking on the relevance button on the right hand side of the screen above where the lists start. It helps!!

Wow $34.90 an hour that is fabulous!!

We use Gooch crucibles with the side arm flasks and vacuum pumps and have had great success. The gooch crucible is a sintered glass crucible with a porcelain filter in the bottom. I think the No.4 is what you need. They are expensive but have always worked for us.

Hi Cindy,
I always put a splash of 2M H2SO4 in my water for the voltameter and it works a treat!

WHY WHY WHY!! Can someone please explain??? When I'm searching in FFX for a chemical eg Cyclohexane and the box pops up on the side when you start typing and you select the most relevant one why doesn't it then take you directly to that selection?? I have just waded through 19 pages of 37 to find th...
