There is a new type of neon potting that has emerged recently.
This new potting is a cream colored opaque polymer of some type.
It is not affected by the solvents normally used to unpot neon
cores. It is recommended that this material be removed by the
"cold-cook" method. Freezing makes the material very brittle and
it will chip away easily, the warm core will allow the polymer
to release from the windings without too much difficulty.
