I'd like to make some trivets like those in Woodworkers Journal, December
No finish is mentioned but I rather think that some sort of finish might be
advangtageous to prevent stains from any food spillage. But, what sort of
clear finish will be heat resistant? And imagine a pan coming fresh from
the oven at 450 degrees!
I haven't heard of one. IIRC, wood will scorch at that temp, and some
online looking for a few minutes indicate that some low density woods
will actually begin to burn (not flame, just char) at that temp.
I don't think you could use a resin finish as they are much too
susceptible to temps problems. After all, when they are dry, most are
simply plastic coatings adhered to a surface. Most plastics melt at
pretty low temps.
You might try mineral oil. I use it on my home made spatulas and
even when frying (I know... it isn't at 450F, settle down...) I don't
have any problems with the oil protecting the wood. it is easy to
apply, easy to renew, and really cheap.
I've never done this, but you will need a material that can stand those
temperatures, and wood isn't it, I think. Perhaps you can try some manmade
counter material like Silestone. I'm assuming that you can get scraps at a
counterstore. Just make sure your tools are appropriate for it, and wear
dust protection. That dust is bad for you ...
Ralph, I have made a dozen or so trivets for the wife and kids. I find
an attractive ceramic tile (bathroom/kitchen) in the 4x6 range and trim
it out in oak. I support the bottom of the tiles with some Masonite that
is dado'ed into the oak trim so that the tile will be about a 1/32-1/16"
above the oak. I finish the oak with stain and a "GENERAL FINISHES" oil
based finish with a sheen of your choice. These regularity have 'hot'
pot such as a cast iron dutch oven and skillets placed on them. After
many years of service, no signs of any wear and tear due to heat, cold,
liquid and other abuse.
Good luck and enjoy the day
Thanks, Norvin, good idea. Actually, very good idea.
Part of my trivit project is thus: When camping, our group often uses the
folding plastic banquet tables for our group meals. (I probably have
way-overestimated the heat to be placed on the trivets) Some of us use
crude trivets, which are nothing more than squares or rectangles of plywood,
to keep hot pots off the plastic tabletops. I wanted to make something
nicer, for myself as well as others, but also wanted to protect the wood
from any spillage of food or liquids. Can't have it all! I really don't
know the maximum temperature of the pots we set on the plywood but the oven
temperature go up to 450!
I like the tile idea!
