>>> Here is the Element Quiz Question:

>>> The Question:
>>> This element is a metal and has a large variety of commercial

>>> It can be found in nature as a free element and is one of the best
>>> known element despite only being the 35th most abundant on Earth.
>>> The element
>> is
>>> mentioned in the Bible and was known to ancient civilizations. This
>> element
>>> has been poisoning humans for hundreds of years. This element is
>>> used in the Oddy test. Which element is being described?
>>>
>>> The Answer:
>>> The element is Lead (Pb). Lead is used in hundreds of commercial
>>> applications and has equally been shown to be toxic in hundreds of ways.
>>> Lead was added to wine, used in paint, used in gasoline and in
>>> cosmetics before its toxicity was fully understood. Lead chromate
>>> (PbCrO4) is a
>> safe
>>> yellow pigment and lead azide [Pb(N3)2] is used as a detonator of
>>> explosives. Lead derives its name from the Latin word "plumbum"
>>> which is the origin of the English word "plumbing", all associated
>>> with the use of lead for water pipes in the Roman Empire.
>>>
>>> The Oddy test is a procedure created at the British Museum by
>> conservation
>>> scientist William Andrew Oddy in 1973,[in order to test materials
>>> for safety in and around art objects. This test calls for a sample
>>> of the material in question to be placed in an airtight container
>>> with three coupons of different metals-silver, lead, and copper-that
>>> are not
>> touching
>>> each other or the sample of the material.[3] The container is sealed

>>> small amount of de-ionized water to maintain a high humidity, then
>>> heated at 60 degrees Celsius for 28 days. An identical container
>>> with three
>> metal
>>> coupons acts as a control. If the metal coupons show no signs of
>> corrosion,
>>> then the material is deemed suitable to be placed in and around art
>>> objects. The Oddy test is not a contact test, but is for testing
>>> off-gassing.

>>>
>>> The winner of the quiz is Jerry Dengler, Pergamon Corp. and will get

>>>
>>> The EQAB was quite impressed with Doug's submission of "solomonium"
>>> but
>> due
>>> to he submitted silver as his first response, all other submissions
