2 year old cascamite. About 1 hour open time. If you buy a pot of cascamite once a year you can use whichever batch is most appropriate for your use. Cascamite is great for gap filling in certain situations. Not suggesting shoddy work with gaps but there are some genuine situations where a bit of gap filling and chemical hardened glue can be very useful, as well as the extended open time when the glue is a bit past its use by date. Used some recently for turned posts for a 4 poster bed where the turner had made the spigots a little bit sloppy for the bore holes in the lower turned sections. As we wanted to assemble the whole bed at the time the 2 parts of the turned posts were glued together to make sure everything was straight and fitting well, the assurance there was no time pressure, having tested the gluing time of the old cascamite before the glue-up, was just what was required.
just dont try cider, once opened it tends to disappear quite quickly
