The paraffin wax that I use, is a product called Gulfwax, a household
paraffin wax. I used it because it was my wife had it in the pantry and
it is in convenient blocks. At normal room temperature, it is a solid.
Toilet base seals are viscous at room temperatures. It would be pretty
messy and difficult to handle. Normal bee's wax is solid at room
temperatures.
The beauty (in my humble opinion) is that paraffin is easy to handle,
melts because of the friction of rubbing against the moving blade, and
then solidifies when the cutting is over. (easy clean up)
The precaution of avoiding hands close to the moving blade is most
important. i.e. Don't use a small piece of material! Allow lots of space
between you and the moving blade! A candle has a wick that could catch
on the blade with nasty results! Discard small remnants of the wax. (or
you could collect them and melt and mold them into lube-sticks) 8-)
