@Revvy - I have not pressure tested them, I suppose this first bottling if they hold carbonation will be the test. I don't imagine them having a problem, however I don't have a lot of experience with brewing and carbonating.

@Connoryis - That is essentially exactly what I did, for these I normally use a transparent celadon glaze as a liner, pour into them, swirl, dump out. It should line completely but that was one of my concerns because if it doesn't that would be problematic as it is a stoneware bodied clay that would soak in liquid without glaze. I think my next flip top bottle project might be with a porcelain clay, then I wouldn't have to worry as the clay body would be non-vitreous after firing.

I will keep an update, and post better photos .

I do a little pottery too. Never thought about trying to do swung tips. Where did you get the hardware? Was it hard to get the distance right on the holes?

Subscribing to find out if they hold pressure. Hoping so.

@Mathin- The tops are Replacement EZ cap swing tops that I bought online. The holes were somewhat difficult, I used digital calipers to measure the dimensions on an existing glass swing top, I then recalculated the dimensions to account for shrinkage. The width of the neck isn't quite as important because you can bend the metal on the swing tops to fit. The distance from the rim to the holes is a little touchier to get enough pressure to really push down but not too much to where it doesn't fit. After doing the measurements I made a small wooden jig to quickly make measurements while the bottles are still on the wheel. I will definitely be making more, especially if they carb the beer. If you have any more questions let me know.
