Cava vase

I obtained a heavyweight Cava bottle, deep olive in colour with a corked neck and a punted bottom.This would have made a great hanging light, but because of the shape, I wanted to make another cut flower vase, as I had done earlier with a similar shaped wine bottle. The extra weight would make for a particularly sturdy vase. This would require only one clean cut, so not exactly taxing or imaginative, but I want to use the bottle to it’s best possible re-use.

Cava vaseI wanted the cut to be well up the curve of the neck to help emphasise the curving nature of the vase shape, hopefully leaving an opening of around 40-50mm diameter. I selected my point, using the G2 bottle cutter to see where I could get a clean clearance on the cutting wheel without fouling, and set up to get a clean score line. The glass was pretty flawless, with a reasonably clean seam, so scored well. I used my regular hot water method to run the score, and as the glass was thick, I kept the water temperature quite high around 80 degrees celsius. I gave the bottle at least five full revolutions to ensure the glass was really warmed up well, and I could feel the heat coming through to my grip at the bottom of the bottle. A quick revolution of the bottle under the cold tap ensured the line of break was fully complete and visible under reflection in the light. A second pour of hot water separated the neck with a pretty clean edge, sloping inwards as is the case when cutting on the curve.

The glass was up to 6mm thick, and I took almost an hour to very carefully finish the edge using the diamond blocks, as I wanted another perfect example. the opening size was around 50mm, so was a tricky fit for the pads, but care taken ensured a great end result, with the one edge pit eliminated, and the inward sloping edge retained. With the great colour, heavy weight, and good surfaces, this bottle became a great looking yet very functional vase.
