FWIW I have an old Lamello Glue dispenser that injects measured amounts of glue into biscuit slots. The instructions indicated to use a White glue as it tends to give more working time when putzing with biscuits. That said because this dispenser is more for production runs I do not use it unless putting in 150+ biscuits on a job. I typically squirt a dab of yellow out of the original glue bottle into the slot for small jobs.
