How can I keep my glue from drying out and getting hard? I buy a bottle of glue and use half, then before I can use what is left, it is hard and gets thrown away. This is a waste of money and glue.

Chris Marshall: You don’t mention what kind of glue you are using (my CA glue seems to dry out in a New York minute!), or how long it’s taking to dry out, but I’ll presume you are using ordinary yellow or white PVA woodworking glue that’s reasonably fresh. Glue gradually loses its moisture as it ages and thickens, which hastens the dry-out problem. One option would be to buy smaller bottles and squeeze the air out before replacing the cap. Then, you’ll not only have fresher glue when you need it, but also less glue lost to the trash if it should happen to turn to stone in the bottle again.
