Co-op at 71st and Fifth Avenue, ca. 1960, is
replacing its white glazed brick facade, due to the usual failures. In
this case they have chosen ... white glazed brick.
question 1: why are there little raised
black specks on the glaze? To make it look interesting, But not
very.
question 2: is currently produced white
glazed brick better than the 1960 version? It MAY be. Glazed brick
wasn't well understood back then and is GENERALLY better understood now.
The question is whether the current a/e specified and the manufacturer
provided a GOOD brick which will not be overly water-absorbent and will
therefore be frost resistant or were the failures due to
maintenance? Not a maint issue. The old brick absorbed too much water,
which got stuck behind the glaze, froze and
spalled.
