Terry, look at my post and you will see; "...BTW paraffin and mineral
oil can be mixed to change the viscosity to anything from solid to
liquid and everything in between! I would suggest that after you pour in
the paraffin that you keep the capacitor at the melting point for the
parafin for a while (like several hours) to let any bubbles rise out."
Perhaps I should have added that the mixture of paraffin and mineral oil
shrinks less upon coling and is not brittle when cooled. You are right
though vaseline is also misciable with both paraffin and mineral oil,
infact it is quite comon to see vaseline (petroleum jelly) and mineral oil
mixed together in various burn and abrasion creams so it will have a
better consistancy and in many lip balms paraffin or more commonly carnuba
wax (it's harder than paraffin) is blended with either petroleum jelly or
mineral oil for better consistancy. I know the pharmacology seems out of
place here but it exemplifies the misciability of these materials.
