Tempered glass cutting boards OK for knives?

I saw a glass cutting board I'm interested in. The manufacturer says they're safe for knives, don't dull them. Anyone have any experience?

I seem to wreck whatever wooden boards I encounter. I buy good quality...I don't submerse them...but they all seem to split... Not crazy about all the cut marks in the plastic (or whatever manmade material they are) boards, because I don't think they have the antimicrobrial properties wood does.

So...what about the tempered glass? Thanks if you can help.

  1. Bah! The manufacturer, wanting to sell cutting boards, is giving bad information. Not surprising - knifemakers also say it's OK to plop their knives in the dishwasher, but NO high quality knife should ever see the inside of a dishwater, either. Wood, and that plastic you describe, are the only suitable material for cutting boards. Cutting on any hard surface will damage your knife blade: granite, marble, ceramic or porcelain tile, Corian, formica, tempered glass etc. People adamantly claim differently, but plastic and wood (properly maintained) are identical from an antimicrobial standpoint, so take your pick. As for a good quality wood board splitting, it's probably over dry. Plunge your entire board into warm soapy water, dont let go of it, rinse and towel try promptly, then apply a thin coat of non toxic mineral oil every so often, It's a dollar or two for a quart at any drug store. Cutting boards are sacrificial items. They are meant to deteriorate over time and be replaced. If they were meant to stay pristine, we'd be carving, slicing, and chopping with abandon on our butcher block counter tops. When any two materials clash, something's gotta give. Ridges, cut marks in your board reassure you that your blade is not doing the surrendering. Every so often a board can be sanded smooth and then oiled as above. After tons of use and innumerable sandings, I suppose a board would need replacing, but not for a very long time.

      There is simply no worse cutting board than a glass cutting board. The. Absolute. Worst. I wouldn't be responsible for what I did to anyone who so abused my knives.

      As for wood cutting boards, I agree with everything fatcat says. Take good care of your wood cutting board, and when it dies, mourn it quietly, and get a new one.

      1. re: fatcat55jc

        I agree completely with your comments. My primary cutting board is wood (maple, I assume) and has been in daily heavy use for approximately 40 years. About 20 years ago, it had developed enough of an uneven surface to make things difficult, so I had a woodworking friend of mine run it through his commercial planer, which restored the surface to good as new. (I remember my friend mentioning that after running the board through the planer his workshop smelled of onions and his dog tried to eat the shavings when his back was turned.) In the second 20 years of its life it's managed to maintain a very even surface, for reasons not apparent to me. I have every expectation that it's going to last at least another 30 years, and I can only hope that I'm around to see if it does.

          Actaully, laboratory studies have shown that wood has, in in of itself, antimicrobial properties and plastic does not. The links to the journals have been posted before so I won't beat a dead horse.

          Good quality wood boards can last for a very long time and certainly are more asthetically pleasing than plastic.

        2. Don't know about the effect on knives, but I hate using those and actually think they are dangerous as the knife slips around when it comes into contact with the board. Cringe just thinking about it.

          1. Negatory on the glass cutting board. It will ruin your knives.

            As another poster stated use it until you can't and give it a good burial. jfood is stopping at L&T on the way home tonight to buy a new bamboo board and when he gets home the white plastic one will hear "taps." and he loved that board.

            1. You've already gotten the best advise to by pass the glass cutting board. Now let's see if we figure out why you ruin all your wood boards. First buy a board that is at least 1 1/2 inches thick. Less than that and you risk warping. A hard wood like maple works well. Pretreat that board and load it with mineral oil. The board will soak it up quickly in the beginning. Continue adding oil until it doesn't soak it up. This will help keep water out which will cause the wood to split. Every month or two re-oil the board. Every year if it's really worn give it a light sanding and re-oil.

              1. No, are you kidding?

                Seriously, get either a good bamboo cutting board or a good wood one - I have a solid one made from one piece of wood - probably had it 20 years - never put your cutting board in the dishwasher! Disinfect with hot water and soap and if you cut meat use white vinegar and hot soapy water. Good luck!
