How to  Cut Bottles for Crafts

We use glass bottle to recycle old wine bottles is to use them for home decorations. Do youbneed if you need to change their shape for the craft in some insights ?, Now you find that cutting them takes a lot of practice. While you're dealing with glass, it's very important that you learn to cut wine bottles the right way.

Method 1 of 2:

Using a String

Wrap a string around the bottle several times, then tie it on. You want to wrap it at least 3-4 times tightly around the widest part of the bottle. Then cut off the ends of the knot.

Slide the wrapped string off the top of the bottle. Keep it tight, trying to leave the string in a nice ring.

Soak the string in acetone, which is often used as nail polish remover. The acetone will burn, heating the bottle along your string line to make it break off cleanly. It only needs to soak for a few minutes.

You can Slip the string back on the bottle, stopping it roughly where it starts to taper up into the neck. You should put where you want totcut the glass  put the string anywhere, depending on how tall you want your bottle. Thereis no problem if one   is bigger or small is more or less where the bottle will cut.

Light the string on fire over a tub of water, with the bottle held horizontally.The string should catch quickly. Always have your bucket of water right there on hand to prevent any mistakes or accidents.

Spin the bottle as it heats up to distribute the heat evenly. Use both hands to turn the bottle as if it were a piece of corn. Keep spinning until the acetone stops burning, which is usually when it starts to smoke.

Dip the bottle in cold water to "cut" right at the hot, flaming string. The abrupt change in temperature should sheer the bottle right where the flame was. Take a piece of sandpaper and smooth out the edges to prevent any possible shards or rough spots.

Method 2 of 2:

Scoring and Slicing

If you are Buying  an industrial bottle cutter or sharp precision knife. These are small machines that are made to evenly slice rounded pieces of glass. You likely won't need one for much else than this, but bottle cutters are helpful, cheap tools if you're doing this a lot. Otherwise, a glass cutting knife or sharp, precision blade will do just fine.

Snugly wrap an industrial hose clamp around the wine bottle to provide a "tracing" line. Place it wherever you wish to make the cut, ensuring that it is sitting evenly. This clamp will provide your guidance line when scoring the bottle, like using a ruler to draw a straight line. You could also use a roll of masking tape with the bottle shoved in the center to provide a nice, straight line.

Using a sharp, precision knife, score the bottle by following your tracing line. Follow the line of the clamp to unsure an even cut. Work slowly and methodically.

• You may have to trace out this line 3-4 times to get a nice, deep score. Note that you aren't trying to cut through the bottle, just create a nice, even line.

Heat the line you scored over a candle. Rotate the bottle so that the whole line gets nice and hot. Heat changes cause glass to weaken, and your already scored mark around the bottle will help speed up the process and ensure and even break.

• Heat the scored line for about 5-6 seconds.

Rub an ice cube around the scored line. You will hear a slow breaking sound as you do. Carefully pull apart the two bottle pieces.

Reheat the bottle and reapply the ice cube if it doesn't work at first. By the second or third application, the bottle will slide away and you'll be left with two distinct pieces.

Sand away any rough edges before using. While this method creates a relatively clean break, you can never be too careful. Sand down the rim to get rid of any jagged or rough edges.
