Sep 29, 2019 at 19:42 comment added Stan 100% wool yarn also works for this technique. I have never tried cotton string. This in addition to scoring the glass (green glass jug) helps determine accuracy. My attempts were never "clean" cuts, though.
Aug 19, 2016 at 10:46 comment added user17316 As for what kind of yarn or string to use...use 100% cotton. Poly blends melt. Cotton burns evenly.
Mar 10, 2016 at 21:18 comment added Jon Just a thought on the type of string, it should be a natural fiber like cotton, manmade fiber is going to tend to melt and stick to your glass and may prove very difficult to clean off.
Mar 10, 2016 at 15:48 comment added Adam Zuckerman I haven't used this method for plate glass (family has in a pinch), but it would make sense (to me) that it breaks directly on the burn line.
Mar 10, 2016 at 7:36 comment added kamuro As long as the string can hold enough liquid, it should be fine, since the fumes of the liquid will burn before the piece of string starts burning. However, I would guess that this technique is not really suitable for a glass plate. Also, can you tell beforehand whether the beak will occur left or right of the string? Since it is not hottest directly under the string I guess it won't break directly underneath, correct?

Provide guidance on what type of string to use.
Mar 9, 2016 at 21:27 comment added Adam Zuckerman I would use twine or yarn. I'll update the answer to include this.
Mar 9, 2016 at 21:01 comment added Broots Waymb What kind of string can you use for this? I feel like simple thread would burn into pieces within a second of being lit.
