They were half right. It's DIFFICULT to glaze it now.
Since the clay has been vitrified, it's hard to get glaze to stick to the surface.
Your best bet is to heat the pieces... I've done it with a heat gun for touching-up spots, some people do it in an oven, and some people will put them in a kiln on low.
While the pieces are hot, you'll have better glaze adhesion. It's still difficult, but less so.

I was trying the same, heating in a microwave to reglaze. Blew it up, not really but it popped and quite working. That was an expensive $15 pot. Now I use a heat gun with the pot rotating . For a bunch of items I would be likely to use our gas oven or even the kiln to about 200 F.

I wouldn't put anything in a microwave but food that you intend to eat. I also would not put food in a kiln. I knew,repeat knew an art teacher who died of cancer of the throat. He cooked garlic sausage in his school kiln at lunch.
Get a heat gun, or put pieces back in the kiln on low.

Sounds like your workshop needs to have defined areas for ware for different processes, does your group do raw glazed firing or was a complete novice operating the kiln? Either way sounds like some organization/ ground rules need to apply other wise some one will just use anything around to fill up the kiln so whatever firing they want to get on with is commenced!
Very disappoining for you. ANd I am amazed some of your raw ware did not get completely distroyed when taken up in a glaze fining.
This needs to be sorted out otherwise you could have ongoing issus about:people handlimng or mishandling your work, and worse still, as has already happened to you.
Poor second, but have you thought of perhaps painting or even mosaicing onto your pots, or any other type of finishing process, what cone did your fellow kiln user take the pots up to?

I learned a little more info on what happened to the load. She was doing a bisque load the kiln and then proceeded to fire them all to cone 5 We do have defined areas in our guild. I guess this was just one of those moments

If you use a microwave, put water inside the pot . . . a bare, empty pot will overheat or get too hot to handle. Microwaves generate heat and cook things by agitating/exciting the water molecules within the item being cooked.
My bad . . . reheat bisque in an oven, not microwave. Was thinking of a former student who wanted to reglaze a bowl; told him to heat it in the microwave, then do his glaze dip. He did, but the ware nearly burned him -- he heated it empty and for too long.

Taking them home! Any way of safely transporting glaze ware??

Thank you, thank you for the link. I get called to do ceramics units of work for schools and absolutely freak when transporting students work home, it's always other peoples' work or commissioned stuff that gets you!
Good luck with the refiring! I was going to suggest trying just one piece, and then getting on and producing some new stuff. When the wound is not so raw and you have some more beautiful pots in your life, go back to the overfired bisque and play a bit...., or build something in the garden with them.
