Hi Guys,

The inventors of NPL Super Black conducted two sets of parallel experiments. One of these might be described as purely scientific with all the usual controls and attention to the smallest details. The other set was deliberately messy in the industrial sense. For example, on one side purified water was used - on the other plain tap water was substituted. The author's expressed purpose was to establish that the new black could be made in a normal factory.

Hi Kate,

I think that my old member number was 686 or 668 or 684 or at least in the six hundreds. Well, I've never been accused of being detail oriented or having a good memory.
