After many unsuccessful attempts at cutting wine bottles ...to re-purpose into other products such as
candle lights...containers with the bottom that is cut off...I finally found a device that works. It is from a company called Diamond Tech...Tampa, Florida.. There is quite a learning curve with this device.
When I first tried to use...I broke about 30 wine bottles...(No..I did not drink all that wine...I have to confess I rescued them from our Glass re-cycling bin!!!!) The setting has to just so exacting...if anything moves while cutting the bottle...it is a mess-up! But I now have it down to a science and so rewarding when you get a clean break. After scoring the bottle all the way around...you dip bottle into boiling water
