There’s obviously a lot of different styles of bottles, and also bottles can vary dramatically in quality and ease of use when it comes to this hobby. Learning the characteristics of the sort of bottles you can easily obtain locally comes from practise, and you can soon get a feel for a number of brands whose bottles just kind of work for you. One such bottle that has been working a treat for me is a J.P.Chenet small wine bottle (18oz) which can be seen in this link here : http://www.jpchenet.com/cabernet-syrah-en.html
It has an elegant thin neck, with a wide embossed shoulder, which makes for a great base for an elevated tealight holder, say for a table centrepiece or a mantlepiece. The size is nice, and rather fortunately , as it’s just a bit much for a normal wine glass, you tend to get the bottle presented to you from the bar to finish pouring , and to then take home with you! At first I had written the bottle off, as it has a strange side indentation, as well as a cut-in groove on the base, but in the end , the neck interested me most so I tried one. The bottle rotated fine on the Ephrems cutter, and the score ran cleanly. One thing I noticed was that the glass was much thicker on the back of the bottle than it was at the front where the emboss was – obviously a result of the embossing procedure, but it caused no difficulty.
The neck lends itself well to using another single portion wine bottle body (centre) or a beer bottle sized body (left & right) to be added, as in the photo to the left. An elegant end result, and I’ve now made four of these so far, with only one ‘failure’ through bad technique on my part. A good solid bottle to work with.
