An easy project: about 30 minutes. Materials cost about $2 to $5. You need 6 things, including cut glass bottle or jar, safety glasses and dust mask. The 8 steps start with check the Sharp Rim of the Cut Glass Bottle and wet the 80 Grit Sandpaper for Smoothing Cut Glass.","totalDurationSeconds":248,"videoDurationSeconds":248,"difficulty":"easy","project":{"difficulty":"easy","projectMinutes":30,"waitMinutes":null,"totalMinutes":30,"estimatedCost":{"currency":"USD","min":2,"max":5},"yield":"1 smoothed glass"},"tools":["safety glasses","dust mask","tub of water","paper towels"],"materials":["wet/dry sandpaper, 80 to 2000 grit","cut glass bottle or jar"],"steps":[{"number":1,"title":"Check the Sharp Rim of the Cut Glass Bottle","text":"Look closely at the cut. A freshly separated bottle never has a flat top. The rim dips and rises, and both the inner and outer edges are sharp enough to cut skin. Handle it by the body, not the rim. Put on safety glasses and a dust mask now. Sanding glass makes fine dust, even when you keep everything wet."},{"number":2,"title":"Wet the 80 Grit Sandpaper for Smoothing Cut Glass","text":"Lay a sheet of 80 grit wet/dry sandpaper flat on your work surface, grit side up. Pour or splash plenty of water over it. The paper should stay wet through the whole sanding stage, so keep a tub of water within reach. Water holds the glass dust down as a paste and stops it from floating into the air."},{"number":3,"title":"Sand the Cut Glass Rim Flat in Small Circles","text":"Turn the bottle upside down and set the cut rim on the wet paper. Hold the sheet still with one hand. With the other, press down and move the bottle in small circles. Give it a quarter turn every so often so the pressure spreads evenly. Holding it one way the whole time wears one side down faster and leaves the rim lopsided."},{"number":4,"title":"Wipe the Glass Rim to Check the Sanding Progress","text":"Every few minutes, lift the bottle and wipe the rim dry with a paper towel. The sanded parts look frosted and flat. Any shiny spots or dips are still low and need more time on the paper. Keep sanding and checking until the frosted band runs all the way around the rim in an even ring. This stage takes the longest."},{"number":5,"title":"Sand the Inner and Outer Edges of the Cut Glass","text":"Once the top is flat, round off the corners. Wrap a wet piece of the 80 grit paper over the rim and rub it along the outer edge, turning the bottle as you go. Then work the inner edge the same way. Go slowly here, since your fingers are close to the glass. Stop when no part of the rim feels sharp."},{"number":6,"title":"Clean the Glass Grit Off the Table Before Polishing","text":"The first stage leaves a gray slurry of glass and sandpaper grit on the table. Wipe it all up with a damp paper towel before you move on. Loose coarse grit under a finer sheet will scratch the rim again and undo your work. Rinse the bottle too. Then lay down a sheet of 150 grit paper and wet it."},{"number":7,"title":"Work the Glass Edge Through 150 to 400 Grit","text":"Each polishing stage follows the same pattern. Sand the flat rim in circles for a minute or two, then sand the inner and outer edges. Wipe the rim dry and look at it. Move up to 220, then 320, then 400 grit. Every stage removes the scratches from the last one, so the rim gets smoother and less cloudy each time."},{"number":8,"title":"Polish the Cut Glass Edge With 1000 and 2000 Grit","text":"For a glossy finish, keep going with 1000 grit wet/dry paper, then 2000. Use the same routine: rim first, then the edges, plenty of water. The 1000 grit makes the biggest jump in shine. The 2000 grit adds a little more polish on top. Rinse and dry the bottle, and it is safe to drink from."}],"commonProblems":[],"recipe":null,"lastUpdated":"2026-10-27T14:13:08.406Z","published":"2026-10-27T14:13:08.153Z","license":"CC BY 4.0.
