Wick Safety: The Facts About Zinc and Tin Cored Wicks
In recent years there has
been a great deal of concern over the potential for lead emissions from
candles. While recent studies have concluded that lead core wicks can emit
unhealthy levels of airborne lead, there have also been questions as to whether
other types of metal core wicks can also emit lead. The zinc and tin wire used
in Atkins and Pearce wicks is not a lead alloy; they are pure zinc and tin.
Like all nonferrous metals, the zinc and tin have traces of lead impurities.
For the tin the maximum lead content is 0.08%, and for the zinc the maximum
lead content is 0.004%. Any nonferrous metal will have similar trace elements
of lead. To ensure the safety of the zinc and tin core wicks, Atkins and Pearce
has commissioned closed chamber burn tests. In these tests candles with both
the tin and zinc core wick were burned in closed chambers. A filter captured
the emissions of the candles. When the filters were analyzed, no lead was found
for either the zinc or the tin cored wicks. To review the full text of the
studies, please refer to www.braidway.com. The testing was performed by Ungers
and Associates.
