The formula of the famous Halcyon 11 wax ( actually microcrystalline wax too ) is based on that of the Renaissance wax, dating from 1955. As the H. is somewhat troublesome to obtain in Europe most European and also members of the International Peterson Club are very enthusiastic on the Renaissance wax. One does not need a buffer and I mostly apply it on the rusticated bowls. No odor what so ever, but that is only my nose telling me
Sure, it be can applied on almost anything, like stone, leather, oil paintings, bakelite and guns too.
So does the Halcyon, it even says so on the packing. Difference between the two is hardly noticable. Carnauba wax looks great and lasts for three burns or so.
A good quality pure beeswax does a perfect job, will not last that long, but I like to buff my pipes every now and then. And what to think of sophisticated nutral shoe polish that contains mostly carnauba ? When the rim of your bowl gets weary because of all the cleaning a LITTLE shoe polish works perfect to bring back the color of the stain.
Maybe there's a lot of humbug too on so called special developed products ...
