How to use a wet tile saw to cut glass bottles

Step 2 Choosing your bottles...

In choosing a bottle to cut on your tile saw, keep in mind that lumpy, bumpy
or odd shaped bottles are a little more difficult to cut straight.

Shown in this post are examples of different bottle shapes.
At left is a bottle shape typically used for Chardonnay and Pinot Noir.
Note the bottle shape allows for slightly over half the bottle
length to be cut into rings easily. Once you begin cutting into the
angled neck of the bottle, it is more difficult to keep the bottle flat
and straight, thus you must rely on your hands to hold the bottle straight
for cutting. Please note, you can use rings of all different shapes and
sizes.

The bottle in the middle is often bears Cabernet Sauvignon, Bordeaux 
blends and such. The shape allows for more straight cutting and a taller
cylinder. The bottle on the right is almost a perfect choice, allowing you to cut rings
all the way to the top of the bottle, or to provide an even taller cylinder.
Think candle holders!

Remember this little bit of information when shopping for bottles,
especially at a recycling center. And speaking of recycling, don't feel
guilty at all about only getting a few rings out of a bottle. Keep a big tub
nearby to put all the scraps into, then be sure to take them to the recycling
center.
