Glass Cutting Oil, Suitable for All Glass Cutting Tools, 4 Ounces Glass Cutter Oil is Used for Cutting Glass, Stained Glass, Glass Bottles, Tiles and Mirrors

We bought this because we are building partial walls out of cut bottles. And boy-oh-boy did we need to find an easier way! This little unit works exactly as advertised. Keep in mind that it WILL NOT cut the bottle all the way thru… it’s not supposed to and that expectation is totally unrealistic. It simply scores the glass. We have cut everything from wine bottles to beer bottles to Jarrito bottles and everything in between. If the glass is smooth and not ribbed, it’s going to work. While it’s easy to use… you have to follow the instructions and be patient with the process. Any failures is not the fault of the unit itself, it’s simply the luck of the draw. Not every bottle is going to cut perfectly. There are a lot of variables…. Including the thickness of the bottle. We had been cutting bottle after bottle all day with a lot of success and then tried a Bud Platinum bottle (for that beautiful blue glass) and it shattered almost immediately. It was MUCH thinner than the others and our usual amount of pressure was too much. So we adjusted our technique for different types and have now had great success with the Bud, as well. TECHNIQUE FOR SUCCESS: We found that getting the label and all of the adhesive off first is crucial. You don’t want to dull the blade or have the blade press the adhesive into the exact spot you expect to cut cleanly. Soak the bottles in soapy water, the labels will slide right off. Then we sprayed a Dawn/rubbing alcohol/water spray and used a wire brush or other scrubber, steel wool, etc to get that adhesive. SOAKING in soapy water was way more effective (and cheaper) than Goo-b-gone and all that other stuff. Now you’re ready to use the cutter. Be firm but not crazy. Don’t monkey the heck out of it. Pay attention to where you start the scoring line so you can join it perfectly. DO NOT go around and around… one time only. It won’t look like much but it is enough. Once scored, we would spin the bottle in a pot of VERY HOT BUT NOT BOILING water, heat it up, pull it out, set the bottle sideways in a frying pan with the neck raised on the edge of the pan and slowly spin it while holding an ice cube on the score mark. Repeat as needed: Heat, ice, heat, ice. Sometimes it releases immediately and sometimes it takes a few rotations. But it works. We have been able to cut over 100 bottles so far and have not even changed the blade yet. Well worth the money! The design is simple and effective. It’s tedious work but this unit helps SO MUCH! Thank you!

I bought this to cut wine bottles into drinking glasses. It scores bottles consistently and is easy to use, especially for standard wine bottles. That said, the cut edge is very sharp and still requires grinding and sanding if you want a drink-safe rim. This works well as a first step, but it’s not a complete solution by itself. If you’re planning to make usable glasses, pair this with a glass grinder and wet sanding.

I purchased this well over a year ago. Overall, it has held up well as far as the construction. The only negative so far is trying to find replacement glass bits to fit it. Since the glass cutting blades get dull with use.

I've used it on 4 bottles so far and did as it was supposed to. Good quality, and the instructions on how to cut and then separate were excellent and worked beautifully on my bottles.

Nice glass cutter included with extra blades. As for the "contraption"... meh. Didn't work for me. I scored and scored, then did the hot/cold/hot/cold thing.. no luck. I can't seem to get ANY bottle cut using this thing. And it's clunky, inelegant, unstable, and inaccurate. In addition to a back side brace, it needs a top brace to keep any bottle solid and in place. The wheels are non-adjustable so the size is really only geared to very specific larger bottles (like wine bottles). Not at all easy to use. I would not purchase this again. The value for money was not great. It'll end up in a box in the garage, probably pretty soon. But I will use the glass oil and hand cutter that came with the contraption.

This tool works great. Very easy to use.It does surprise you when the bottle pieces separate. Wet sand the edge of bottle and you will have a glass from your favorite beverage.

This works really good. It takes a bit of practice but I like it.

After using the cutter on 4 bottles, 2 of the screws for the sliding bar got stuck in the holes and when I tried to spin them out, they pulled the nuts out of the wood base. Now the cutter is basically useless.
