Thanks for the temperature advice. Will stick to like warm and crystals then.

Since commenting earlier I have found that the buckets with lids on that fat balls, for the birds, com in make great storage containers, depending on the spool size you can get at least two if not three in them. I also keep mine in their original bags wit a silica gel sachet in for good measure.

Be aware that silica gel does not last particularly long before it has adsorbed all the moisture it can. It is possible to buy silica gel with an indicator that changes from yellow when dry to purple when wet. Silica gel can be revived easily in the microwave a few minutes at full power or more slowly in an ordinary oven. *** Silica Gel with Indicator ***

Do remember that the magnetron in a microwave oven can be damaged by running the with nothing to absorb the microwaves within the oven.

That link says rejuvenate at defrost for several minutes, not full power.

When the silica gel is dried, it may well not absorb microwaves, or will heat up very much more quickly. The tell-tale colouring chemical (a cobalt salt?) will be decomposed if over-heated and then be of no further use.

Of course, as always, it depends on how much desiccant you are rejuvenating at the time….
