I started out saying I store glass in two different cabinets, but when I sat down and thought about it, I actually store glass a LOT of different ways:
Inside "clean" (HAH!) studio:
--Small scrap/valuable bits (like dichro and murrini) in little plastic drawer bins, the kind you buy at ContainerStore or wherever, organized by color/type
--Bigger scrap goes into bigger drawer bins, organized by color and transparency
--Sheet edge cutoffs and long strips go into long white plastic kitchen baskets that I pull out of a lower cupboard when needed (otherwise they're out of sight--I don't use them much)
--Larger scrap and 8x10 sheet are stacked on end in clear plastic magazine organizers, organized by color family
--Bigger clear, white and black scrap in usable shapes (like big rectangles) get their own bins
--Half sheets are organized by color and transparency in a 20x20x24 inch divider bin I had made from quarter-inch acrylic sheet
--Full sheets I need immediately and long 6mm Tekta sheets are stored to the side of my half-sheet bin, against the wall
--Stringer tubes are stored in an art store paintbrush rack
--Rod is in an old acrylic brochures rack, arranged by color
--Frit is on the wall, in narrow video production studio shelves, arranged by color/transparency
(unbelievably) "Dirty" studio in the garage:
--Full sheet bin made of scrap plywood, organized by neutral/warm/cold/clear colors
--Billet is stacked on industrial shelving, by color and brand
--5lb frit jars arranged by color on a waist-high ledge behind the kilns
--40-lb frit buckets on pull-out carts under my workbench
--Clear scrap that isn't in the inside bin goes in to a big bucket on the pull-out carts
--Billet scrap and casting cullet in buckets on pullout carts under my workbench
