Petromax mantles and Butterfly
mantles are not generally available locally, and cost
about $1.10 each plus shipping. The alternative is to
stockpile a bunch of Coleman mantles. Therein lies a
problem. The Coleman STYLE or SIZE of mantle will
work on a kerosene pressure lantern at low
pressure, BUT there is a difference in the
construction style of Coleman size mantles.
Petromax and Butterfly mantles are
constructed with a thick thread, open mesh
appearance. Coleman mantles are generally of a fine
thread, dense weave construction - not the same. But
the ersatz Coleman mantles, off - brand, such as the
Century Model 2295 Slip - On Lantern Mantles, are
constructed with an open mesh similar to the
Petromax. And the Century mantles are manufactured in
India - not China!!!
I have purchased some of all three
varieties, but the predominant ones I use are the
el-cheapo "Century" version. They will still put out
over 200 watts of light, and with the open mesh style
of construction should allow excess pressure to
escape without blowing out the mantle: it hasn't
happened to me yet, anyway.
Coleman mantles are available at
Wal Mart for about $2.94 for 4, or $0.74 each. The
"Century" mantles at Wal Mart are priced at $0.96 for
2, or $0.48 each. The price of the Century mantles is
50% less than the Coleman brand, but that is simply a
bonus - they are better adapted to the
Petromax/Butterfly pressure lanterns than Coleman
brand mantles. Full size Butterfly mantles are
available from SurvivalSupplyCanada.
