If the following is true:
Lagavulun = sucking on a wet burnt log :: Laphroaig = chewing a peat bog
Then one could conclude that:
Black Label = licking the wet char from a summer beam in an 18th century frame
Which means:
Black Label :: ????
(a) the big bottle of Jim Beam at the Liquor Mart down the street
(b) the gelled gasoline in an Old Mr. Boston bottle (in the "well" being sold as Scotch)
(c) a case of Clan McGregor in plastic jugs
(d) none of the above
(e) all of the above
(f) i don't drink scotch
(g) only an long-lurking engineer would think of a response like this...

Best part of being on this list is knowing I'm a woodworker!
Glad to share the single malt wi'ya.

I think the concept of quantifiable vapor transmission is a hell of a lot
more complex in masonry than it is in homogeneous thin membranes for which E
96 is generally applied. Brick and mortar have variable permeabilities
dependent on where measured. Mortar is even more complicated once original
water content, tooling, and aging effects such as carbonation are
considered. My worry is having people hang their hat on a single number
without understanding the biases. Better method?...Full-scale E 96. Seal
your entire building with epoxy, heat to 90 degrees, fill your bathtub with
water, enclose the entire building in a Lucite bubble and measure its weight
changes over several weeks. But seriously, I don't have a problem with the
method, only in how the results are applied to wholesale masonry.
Understand what you're measuring and the results can be illuminating.
Otherwise, it's like assuming that drinking single malt is equivalent to
sucking on a wet burnt log just because you had one sip of Lagavulin.

John,
I have long argued that the method does not yield highly reproducible
results for mortars, but yet you see it referenced over and over in mortar
studies and histopresto grad students think it's g-d's revealed word. What
can you recommend as a better method?
I have also long argued that because of the lack of inTERlaboratory
precision, it is virtually meaningless to compare various manufacturer's
product data sheets. The exception would be studies conducted in the same
lab under the same conditions, because the inTRAlaboratory precision is a
hell of a lot better.
