I use 1/2 gal. plastic containers with snap on lids. That way I don't have to worry about them bursting, which I've heard stories of with glass. I simply sanitize them with StarSan.
I'm with Denny on this. I use 1 liter Rubbermaid beverage containers that have a screw on lid with a spout that has a snap on lid.
I've had some of these build pressure and I wouldn't want a yeast explosion in my fridge if a glass container cracked. Plus, the beverage containers fit perfectly on the door.
I use mason jars for my stored yeast, but I drilled a hole in the tops, inserted a grommet, and use a small, two-part bubbler to relieve any pressure. May be a "belt & suspenders" approach, but I haven't had any yeast grenades in the frig.
