I'm almost weeping at the thought of demi jons ending up thus ruined. You've been warned before about bringing your private life onto the forum. I think Sarah's technique sounds by far the best - nothing sharp, nothing burning, just a little boiling water, that's all!

Sink the glass into cold water just deep enough to come on a level with the wire, not quite covering it. Heat the wire red hot and lay it upon the scratch. Have a piece of wire bent to the desired shape you want to cut the glass. Method 2: First, scratch the glass with the corner of a file or sharp graver. This quick, sharp stroke will break the glass where it has been weakened by the burning string into a clean cut. Strike the glass with your other hand outside the line of cutting using a stick of wood and hitting a sharp stroke. Immediately, while the glass is still hot, plunge it into cold water.īe sure the container of water is large enough to let the glass go completely under as well as your arm up to the elbow, so as to deaden the vibration when you strike the glass. This string should then be placed on the already marked glass and tied tight. Method 1: Dip a piece of string in alcohol or paraffin or petrol or some such and squeeze dry or as dry as it will get without dripping. Gloves and goggles would be a wise choice me thinks. After rotating for a few moments a wet wire was placed on the break line and the top broke off cleanly. I remember seeing a programme a while back where the glass bottle was placed on a turn table and a small flame pointed at the break line. Or she can rummage in my tool box as we have one. When finished with, they can go to the bottle bank. I think they look good in raised beds as well, more aesthetically pleasing than the plastic ones. The advantage of these is they have a good amount of space inside for the plants to grow on, and water can get in the top, and air. They are quite bulky to store, but I leave them outside over the winter when not being used, lined up tidily in the garden. TEsted and reliable method, and fairly safe, with care.

The funnel is vital to stop the boiling water splashing on the sides, as it will cause the jar to crack where it hits - this way the boiling water goes exactly where it is needed. Where the boiling water meets the cold on the outside, the jar will crack fairly neatly and safely around its curcumference. Take a funnel, put into the neck of the demi-john, and pour boiling water in, carefully. Put the demi-john into a sink, put in the plug and run cold water in, up to that line where you want the cut to be.

Take one demi-john, and decide where yu want the cut to be. I'm not allowed to do things with paraffin and matches I've been making for years them from old demi-johns that for one reason or another I can't get clean enough to use for brewing. It is the tool that the writer refers to in the article about demijohn cloches. There are indeed some other nice projects there, one for the GYO sticky I think. The trellis planting grid idea is brilliant - so simple! Any volunteers to try it and see if it works? Probably you wrap the cord where you want the cut and light it - this will create a weak point around the bottle where a quick tap (or whack) will release it. There is also a technique involving a piece of string soaked in paraffin or some such, but I can't remember exactly how it works - or where I saw it. You could probably put the bases in the glass recycling bank as usual but you'd be getting much better use out of the top bits instead of having them ground down/melted. Now I suspect this is an awful waste of demijohns but still, wondered if anyone had tried it? I was thinking that the apple juice we have started buying comes in quite large based bottles, which might not be too bad for this, or perhaps there are other large glass bottles I haven't thought of. They showed how you can make a clean, smooth cut around the base of a demijohn, removing the bottom and leaving you with a nifty little cloche.
