A colleague fetched in a Heinz 57 tomato sauce bottle to see if it was any good to try, so have given it a go. The bottom of the bottle is quite promising, with octagon faceting, with radius tops at the neckline. Above that the neck returns to a round shape, has four of the famous ’57’ logo numbers and tapers away forming the neck.
The shape dictates using a vertical aligned cutter, in this case I used the G2. The neck opening is larger than most wine bottles, and I wondered if would cause an issue of control when the cutter was spun in the opening, but it fitted fine. The only viable cutting line to leave a nice design was just above the ’57’ numbers. The cutting head was at an angle, so I had to keep a firm grip on the support arm and be careful to ensure the line didn’t drift up or down as it sometimes can as you move round on the more awkward shapes. The cut was clean enough, and these ketchup bottles are slightly thicker than most beer bottles, so it broke relatively cleanly, and presented no difficulty to careful arrissing of the edges.
The end result isn’t a bad looking pot at all, with a bit more about it than some bottle chops. For use it could be a little mini-vase say for a kitchen window cill, but in this first instance, I’ve ordered some red wax dye, and will pour a ketchup coloured candle into it. I’ll try to add a photo of it in the near future if successful.
