A good wax medium may work to keep the surface of porcelain clean. It
would be worth while to do a test on some pieces and find out.

Dorlands Wax Medium can be used as a final protective coating for
paintings, wood, plastic objects, metal objects, even photos and paper.
It contains different types of wax, including bees wax and ozokerite
wax. The flash point of the wax is 175 degrees F. It could be bisque
off of porcelain if it didn't work .

It is made by: Siphon Art, POB 710, San Raphael, CA 94915. =20

I have used it on angle iron frames I used for a clay mural. I rusted
new steel and coated it with Dorlands medium many years ago and they
still look the same.

I used Dorland's Wax on a large piece a few years ago.
The buyer was from Arizona, and he drove the piece
home in the back of his minivan, wrapped in a blanket.
By the time he got home, the wax had softened from
the heat, and the whole piece was covered with bits
of embedded blanket fuzz. Since the surface treatment
had colored wax designs below the Dorland's, outright
removal was not an option. The buyer spend hours
with a hairdryer and tweezers cleaning it up.
The whole episode has made me leery of wax. Not
wrapping it in a blanket is easy (I didn't know he was
going to do that), but I still imagine bits of dirt and such
sticking in less obvious ways and building up over time.
When I did foundry work, we used wax as our protectant
of choice, since it can be renewed as it ages, and tends
to age gracefully, unlike lacquer which can peel and look
quite nasty and needs total removal and replacement to
look good thereafter. Wax gets applied hot to bronze when
possible, and cold only when necessary, since hot wax
penetrates the porosity of the metal better. It also gets
the volatiles out quicker. (These are what makes wax go
on soft, and then harden.) Eventually, it loses enough of
them that even hot sun won't re-soften the wax, but in the
meantime, it's still possible, and likelier with cold-applied
wax than hot. Wax and other surface coatings are used
with bronze mainly to protect the surface from moisture
and (light) abrasion, and to make it polish easily; the dirt
factor is secondary. With stone, wax is also used mainly
for polishing. With vitrified ceramics, abrasion and moisture
are almost irrelevant, so wax (in my mind) is really only
worthwhile for its visual properties, and is not optimum
for protection.

Dorlands wax medium is a mixture of different waxs and can be used on
metal, wood, on paintings etc. It has a satin sheen and has worked for
me on metal, on low fire saggar work, on paintings etc. It can also be
used as a final coat on dry paintings, metal sculpture, wood carvings,
and antiques. Since it is made with pure beeswax, it is perhaps the most
authentic final treatment for fine wooden furniture and woodwork, both
antique and modern,
Most art stores will carry this product. Dick Blick, Cheap Joes,
Jerrysartarama , Amazon etc. carries the medium. It comes in various
sizes.
