How do I avoid common issues with glass?

Why have this section?

We typically see the same issues repeatedly arising from poorly configured glass accessories. We hope that by sharing common issues with you we can save you some grief and cash.

Why shouldn't I use a male domeless nail in a female joint?

We do not recommend that you ever use a male titanium nail directly inserted into your waterpipe or ashcatcher. Titanium and glass have different rates of thermal expansion. Hence, when your nail is heated it will expand and cool more rapidly than your glass. When it is a male nail inserted into a female joint, this will inevitably crack the glass joint after enough stress cycles. This is the reason most waterpipes originally designed for oil feature a male joint interface.

We recommend one of the following configurations to protect your glass:

1. Use a dropdown adapter to offset and separate the nail. This has the additional benefit of allowing you to switch to a female jointed nail. This is the most favored solution.

2. Use a male to female or male to male straight adapter to separate the nail from your piece.

3. Use a nail made of a different material. This will still eventually break your glass joint, but a nail made of ceramic has a rate of thermal expansion much closer to your glass, and will hence stress your glass joints far less.

4. Use a male to male adapter and switch to a dome and nail configuration. We recommend this if you want to lower the height of your setup vis a vis your alternatives.

Why should I immediately remove my female domeless nail from my male joint waterpipe?

As discussed above, when heat is applied titanium and glass will expand at different rates. When your titanium nail heats, it will settle farther down onto your glass joint than would otherwise be possible due to thermal expansions As it cools, it will contract and stress the glass joint, since the nail was never meant to sit that far down. It may shatter from the cooling effect alone or when you attempt to remove the nail. If you do this, you should heat the nail back up to its typical operating temperature and only then remove it from your glass joint.
