Last night, i think i ruined my thanksgiving feast...

I fear that i over baked my aluminum Pelican brand silica gel packs.


I have the 40gram ones in the small aluminum pack that you are supposed to bake for 3 hours at 300deg to reset them if they turn pink.


I have been doing this on thanksgiving for years but last night i tried using my toaster oven for the first time ever.  I forgot that it always tends to run hot so i figure the actual temp was closer to 350 when i first put them in.  


Soon after putting 4 packs in the oven i thought i could actually smell them cooking so i turned down the heat but the damage might have been done.


After just on hour they were no longer pink, but now the crystals are more like blackish color.  I do not remember this color for the past years with these silica gel packs.


so here is the question,

In order to figure out if they will still work, could i drop one in a glass of water?  

If it turns pink, then i could assume the other 3 still will work.


But in doing this "test", did i demolish the one i dropped in the water?  

or could i let it drip dry and then bake it again to reset it?


thanks for any input of ideas.

Toaster oven may not work because it is not vented.

Use oven 300F for 3hrs.

Silica gel is CHEAP, so I would just toss any desiccant pack that I wasn't sure about.  100% silica gel kitty litter costs a few pennies per pound (pack into cloth or make an envelope from a paper towel), or if you're near a dealer who sells new Japanese motorcycles, they get at least one big desiccant pack in every shipping carton.

Thanks guys. I ended up just buying new ones and throwing away the old ones.
