Didn't know what "chalk temperature" was so

According to the Titebond site, TB2 is good to 55F and TB3 to 46F. Not
too much of a difference.

Almost 10F and that _can_ be key in cooler weather, particularly
outdoors or in an unheated shop.

Note, of course, that not only the glue but the wood being glued needs
to be at least as warm as the chalk temperature else it will simply cool
the glue to below the threshold. Once there before set up and cured, it
will not bond at all and will turn powdery (hence the term "chalk"
temperature).

The bottle also says that TB3 has a longer set-up time, which can be a
benefit for klutzes like me.

Doesn't have to be klutzy; complicated glueups can tax the skills of
most anybody so the time is often useful indeed as well...
