Wax film is a traditional medium for getting separation between the

make your own from 75% paraffin wax and 25% beeswax. If you have

Toilet ring wax is readily available and also makes paraffin wax less
brittle when cold.


I've heard of toilet ring wax being available in the US and apparently
it is quite good as a lubricant for metal spinning but I mentioned it to
someone in plumbing in the UK and he wondered if you were still in the
stone age in the US as all those applications in the UK/Europe would be
using flexible rubber seals these days. What is the benefit of the wax seal.

It complies with rougher surfaces, including rough tile. It's still
available, but the newer system is a hollow ring of rubber that you
fill with silicone rubber caulking just before you use it.
