Probably Franklin's Titebond Hide Glue.
Some good info here by Jeff Jewitt
errrrrr Brian.... that's one of the good points about hide glue...it's
reversible, it has some elasticity and prior to the 40's was used
exclusively in woodworking - so its been around awhile. Don't know if that
is what David Marks uses or not, just offered it up as an idea with some
urls for the poster to look at and learn about hide glue.
So why do you say - "Definitely not?".
Because its definitely not what Marks is using, which is what the original
question was asking... And in his applications, the objective is high bond
strength with slow setting time for larger glueups in place of yellow glue.
It is a plastic resin glue, available in powder form from, I think,
Weldwood. Has a long open time and does not "slip" after drying as can
yellow glue. Working time for the mixed glue is a couple of hours.
For a while I thought it was Gorilla glue, but he never seems to moisten the
joints. As it turns out, he is actually using urea formaldehyde glues.
Weldwood is one, and is a DAP product that is carried by my Lowes store.
His website also mentions a product "Urac 185" which is available from
