An easy way to cut a glass bottle into a graceful spiral shape. Posting in CHAT: Russia Many people have probably found various decorative items made from glass bottles that decorate open shelves, coffee stands and chests. They look quite unusual and beautiful. But you can make a more exotic decoration than just a bottle, painted and studded with beads, if you cut it in a spiral. When you look at it, it's hard to imagine how this is even possible, but after reading this master class, everyone can make something similar from a bottle. What you will need: Glass bottle; permanent marker; flexible rule; electrical insulating tape; assembly knife or blade; glass cutter; drill; soldering The process of cutting a bottle into a spiral. Any round, smooth bottle without relief is suitable for cutting. It is best to use wine or champagne. The higher it is, the better it will look. The label is torn off, the glass is washed and wiped dry, then marks are applied to the bottle to draw a spiral. To do this, the dots are placed in a row from four sides from the bottom to the neck in increments of 2.5 cm. To ensure that everything turns out evenly, they are placed along the inch marks of a flexible metal ruler. You need to draw with a permanent marker, as a regular felt-tip pen will easily erase the glass. Then take some electrical tape and apply it in a spiral pattern to the bottle. The marks will allow you to make the pitch of the turns the same. Then another row of electrical tape is glued to extend the spiral. Now you need to draw a curve at the beginning and end of the spiral. Then the electrical tape is cut with the tip of a knife along the drawn contours. Then comes the crucial step - you need to scratch the outline of the spiral along the edge of the electrical tape. Using a regular glass cutter for this is not entirely convenient. Instead, it is better to use a diamond drill cutting blade. To do this, it is fixed in the scalpel handle. The scratches they leave on the bottle are deeper. After the outline is scratched, you need to remove the electrical tape. Next, you need to turn on the soldering iron and heat it to maximum. It is advisable to use a tip sharpened diagonally, like the tip of a knife. It is applied to the scratch and held until the glass breaks on it. Then the tip moves a little further along the line beyond the extreme point to which the crack reached. It is necessary to ensure that the marked spiral cracks along its entire length without gaps. If you look at the scratch of the glass cutter at a slight angle, through which the injection has already passed, then these cracks are very clearly visible. When the spiral separates from the main bottle, it must be removed. To do this, use a drill with a diamond cutting disc. The spiral is sawn across, and when it breaks, you will have to move a little more and repeat the cut. In this way, segment by segment, the excess can be completely removed. Finally, the sharp edges of the bottle need to be sanded. You also do this with a drill, but with a grinder. This work must be carried out in a respirator to avoid inhaling glass dust. After this, the bottle can be placed on the shelf. Source link Source link
