Master class: how to cut a bottle with a thread. How to cut a glass bottle with a thread How to cut a glass bottle straight

Gathering at home after the celebration a few wine bottles, I decided to use them somehow. After looking at ideas from the Internet, I ran into the problem of how to cut the bottle myself?

4 ways to cut glass bottle

Make an incision on the bottle. Use a glass cutter or glass drill to make a cut that will break your bottle. If you want, you can use some kind of bottle clamp to make a straight line around the bottle.

Warm up the bottle. Heat up the cut you made with the glass cutter. For heating, you can use a small candle or a butane lighter. Aim the flame directly at the cut line and constantly rotate the bottle so that the heating is even.

Dip the bottle in cold water. When you have spent about 5 minutes warming up the bottle, then dip the part of the bottle you want to cut into cold water. Do it in a sink or basin with cold water.

Repeat the process. For the desired result, your bottle may require more than one heating and cooling procedure. Simply repeat the process of heating the bottle and submerging it in cold water until the desired part breaks off.

Clean up the edges. Use coarse sandpaper to clean up the chipped edges. Once you've removed all the rough edges, use a lighter grit paper. Clean the edges immediately, do not delay, otherwise you will cut yourself.

Enjoy your creation. Use your bottle to hold your pens instead of a glass, or make a pretty vase out of it. The options are endless!

Cutting your bottle with boiling water

Draw a notch line on the bottle. Make a line on the bottle where you want to cut. Use a glass cutter or glass drill to make one even cut around the bottle. Do not overlap the notch line, otherwise the chip will be uneven.

Prepare water. You will need a sink with cold running water, as well as a kettle with boiling water.

Pour boiling water over the bottle. Hold the bottle over the sink and slowly pour over the cut line. hot water from a teapot. Pour the water evenly, do not go beyond the edges of the incision.

Run your bottle under cold running water. Once you've finished watering the incision hot water then start pouring cold water on it. The first time you do this, your bottle will most likely not break.

Continue pouring hot and cold water into the bottle. Remove the bottle from the cold water jet and start pouring boiling water over the incision. Pour the entire line of the cut around the entire bottle, and then slip it under cold water again. After the second or third attempt, the bottle should break along the notch line.

Clean up the edges. Use coarse sandpaper to smooth out chips. When the edges are even, you can use fine sandpaper to make the edges smoother.

Cutting a bottle with thread for yarn

Wrap the bottle with yarn. If you do not have such threads on hand, then you can use any thick cotton cord. In the place where you would like to cut the bottle, wrap the thread for yarn 3-5 times. Tie the ends together and cut off the excess thread.

Soak the thread in acetone. Remove the yarn from the bottle and place it in a small container. Start pouring nail polish remover or acetone onto the yarn until it is completely wet.

Wrap the thread around the bottle again. Take a string and wrap it around the bottle where you want the bottle to break. The loops of yarn should fit snugly together so that you get an even cut.

Light the thread. Use matches or a lighter to light the thread. Slowly turn the bottle so that the yarn burns evenly around the bottle.

Submerge the bottle in cold water. Pour cold water into the sink or basin beforehand. Wait for the fire on the yarn to burn out and then stick the end of the yarn bottle straight into the water. The bottle should split where the yarn was wrapped around it.

Clean up the edges. Use coarse sandpaper to smooth out the sharp, jagged edges on the broken part of the bottle. After removing sharp corners, use fine sandpaper to get a smooth edge on the bottle. Ready!

Cutting a bottle with a dremel

Prepare your bottle. All the cutting work here will be done by your dremel, but you need to know where to cut. Take two strips of duct tape and stick them around the bottle where you want to cut it, very close together but not touching. So you will have a notch line.

Cut the bottle. Insert the glass cutter attachment into your dremel and start to slowly cut the bottle along the line between the strips. You may need to go over the same spot multiple times to get a clean cut.

Clean up the edges. When the bottle splits along the line, the chip will likely have jagged edges that need to be smoothed out. Use coarse sandpaper to smooth out the sharp pieces, and then use fine sandpaper. Ready!

You can order a special tool for cutting wine bottles online if you don't like the methods above.
The temperature of the bottle glass should change gradually, except when you place the bottle in cold water. Otherwise, you will ruin the bottle.

Sometimes you come across just super ideas for design, someone offers a table made of solid wood, someone has shelves made of branches and you have not only desire, but also free time, but ...

To make even the most primitive shelf, you need good (not from the store, everything is 35 rubles each) screwdrivers, corners, “self-tapping screws” desired length, be able to cut smoothly, like the saw itself, plus a drill or even better if the wall is made of concrete. And in the picture everything is just drop dead simple and beautiful!

And if a shelf with some kind of decor? As here:

"Sticks are thrown around at every step." This is partly true, but they are either too thin or too thick or too dry or too rotten. But even if there are ideal sticks in front of the threshold of your door, then you need to remove the bark, at least sand it somehow, and ideally varnish it, otherwise the sticks will quickly darken and age.

And that's just, it seems that they are easy to attach. But what? Drill? Do you have a long thin drill? What about a self-tapping screw that long?

We look forward to creative success from you!

Hello dear readers! Decor from glass bottles, quite popular lately, by the way, this topic we have already considered in the review “Bottles in the interior: they found a use for them!”, And since many are interested in the question of how to cut a glass bottle at home, without using a glass cutter, I want to dedicate today's master class to a simple but interesting way cutting bottles with a thread ...

In this connection, the topic of this master class is “How to cut a bottle with a thread - nothing complicated!”.

For work we need:

Glass bottle;
Woolen threads;
Solvent (you can kerosene, alcohol, cologne, acetone);
Scissors or stationery knife;
Gloves (will protect the skin of the hands from exposure to the solvent);
Lighter or matches;
To protect the eyes, just in case, goggles (in fact, there are no fragments, but caution is never superfluous);
Deep basin filled with cold water.

So, how to cut a bottle with a thread? We take a woolen thread, measure and cut it in such a way that it is enough for 3-4 turns of the bottle.

We immerse the measured and cut thread in the solvent, and immediately wrap the bottle in the place where it is planned to make an “incision”. You can simply wrap the thread or tie it in a knot, in this master class I just wrapped it.

After that, we set fire to this thread with matches or a lighter, and it is better to keep the bottle in an inclined position - strictly horizontally (parallel to the ground), gently scrolling around the axis.

The fire will burn for about 30-40 seconds, as soon as the lit thread goes out - quickly lower the bottle into the prepared basin filled with cold water.

Next, the characteristic sound of cracked glass will be heard, and the bottle will instantly split into two parts. This type glass cutting is based on a rapid change in temperature, we all know from the lessons of physics that glass expands when heated, and narrows when cooled, respectively, with a sharp change in temperature, a kind of glass destruction occurs and it simply cracks!

We figured out how to cut a bottle with a thread, but how to process sharp glass edges? You can use sandpaper or stone to sharpen knives. Lastly, you should process the edges of the bottle, previously immersed in water, so the processing is easier and faster (it is better to protect your hands with rubber gloves). Friends, please do not forget about the notorious safety precautions, after all you will work with fire and glass, goggles on your eyes, gloves on your hands and a basin with big amount water is a must!

Workshop on cutting a bottle with a thread

Everyone is well aware that many useful and original things can be made from unnecessary glass bottles with your own hands. However, not everyone knows how easy it is, because many have no idea how to cut off part of the bottle without a glass cutter. We offer you a master class on how to cut a glass bottle with a regular thread quickly and easily at home without using a special tool.

In order to cut a glass bottle we need:

A piece of ordinary cotton thread.
Acetone or alcohol.
Cold water container.
Matches or lighter.

Thread cutting order

Step 1

Cotton thread soaked in acetone

We mark with a marker the line along which you want to cut the bottle. Wet the thread in acetone and wind it several times along the intended line. We tie the rope and cut off its ends.

Tie the thread tightly

Trim the ends of the thread

Step 2

Holding the bottle in a horizontal position over a container of water, set fire to the thread. In this case, the bottle must be rotated to ensure uniform heating.

We set fire to the thread

Step 3

As soon as the thread burns out, immediately dip the bottle into a container of cold water. From a sharp temperature drop, the glass itself will crack along the line where the rope was.

Dip the bottle in very cold water

Step 4

Separate the two parts of the bottle with your hands

At the last stage, it remains only to process the edge with an emery or file. Further, from the resulting glass, you can make an original candlestick or a flower vase, decorating the product to your own taste, in general, experiment!

Sanding the cut with sandpaper

Today, every day more and more gaining momentum " hand made" creation. Very often, needleworkers use glass bottles in their creations. They make vases, lamps, coasters, etc. out of them.
I will show you a very simple way to cut a bottle cleanly in almost a few seconds.

All we need is nichrome wire, 12 V battery and cold water.

We cut the bottle

First you need to determine the location of the incision. To make it even, take a piece of paper and wrap the bottle around it. Align the edges of the sheet so that the line is even. Then take a felt-tip pen or marker and draw a border around the edge of the sheet. Now the leaf can be removed.

Next, you need to take a piece of nichrome wire with a diameter of 0.5 mm, attach one end to a stationary object. For these purposes, I use a black weight. We immediately attach one wire from the battery to it.

We make a coil around the bottle. And align to the trail of the marker.

In order not to get burned, take the wire with pliers. Pull just a little to straighten the wire.
Apply voltage to the other end of the wire.

It can be seen that the wire is hot. In places of contact with the bottle, the wire does not completely turn red, as the bottle takes away heat.

We wait without moving the wire and holding it in tension for about 30 seconds.
Then we quickly remove the wire and sprinkle the place of heating with water. You can also prepare a bucket of water and dip the bottle into it.

You will hear a peculiar click of glass, and the bottle will burst exactly along the line where the nichrome wire passed.

Everything is explained simply: during the heating of a certain place in the glass, internal stress. After rapid cooling, the glass surface is rapidly cooled, and its inner part it stays warm. As a result of such a sharp change, microcracks appear, which instantly turn into a split.

Such a trick can be done not only with round bottles, but also with square, oval, etc. bottles.
