Re: [MedievalSawdust] Finish for a Throne
- I'm going to sound a contrarian note against the wax and/or linseed oil
finished for thrones for SCA use. This comes from experience: we tried
those finishes on earlier thrones and our personal chairs, and found
that over a few seasons the finish does not offer much protection. IF
someone commits to renewing the finish at least once a year, the thrones
may continue to look good, as you are in a relatively benign environment
(as long as you don't regularly transport the thrones to places with
higher humidity). But, again speaking from experience, the likelihood
that refinishing will actually happen regularly is small.
For that reason, I have chosen to use a more robust finish, namely the
Waterlox Original, which is a thinned oil-and-spar varnish blend. It
penetrates well and, if carefully applied, leaves a beautiful satin that
does not look modern or plastic-y. If wax is not applied over it, the
finish can easily be renewed from time to time, by first rubbing with
steel wool or (better) the grey synthetic pads, wetted with naphtha or
other solvent to remove surface oils and grime. Then you just rub in
another application of Waterlox. This renewal probably wouldn't have to
be done very often in your situation.
I recommend this because it combines the durability and flexibility of a
spar varnish (the best protection for the wood) with the easy
application and "natural" look of an oil finish. All finishes are
tradeoffs, and if you are willing to sacrifice durability for a more
period recipe, by all means use the oil/wax recipes - just be aware that
those are fine for interior use, but will quickly break down in
sunlight, and will therefore need to be reapplied often to keep the
thrones looking good.
Construction matters as well: If the thrones are robustly built, such
that wood movement will not cause structural failure, then you can get
away with a less-protective (more period) finish. The main function of
a finish is to reduce moisture transfer (and thus reduce movement);
appearance is secondary.
- try it in your coffee Jim ...you can tell its been boiled or not.

Boiled. (More specifically, the stuff you get in the big can at the
box stores, which says 'boiled' but really is chemically treated to dry)
