Lead weights for plants

That is true, some added information on lead.
Some Stain Glass workers use gloves as
the lead can be absorbed through the skin.

This topic has been gone through pretty heavily here, and the
concensus generally reached is that it doesn't break down in
freshwater at a high enough rate to cause a problem. But Red should
avoid eating the lead during his project.g

If you want thin flat strips then pour the lead onto a marble surface, as
it's cooling run a roller over it, once set then use a guillotine to cut it.

Otherwise you use aluminium. Making sinkers for fishing is done with
aluminium molds.

I have a lead melter/burner device that melts about a US pound of lead at
a
time. I'd like to find out how to make a mold to shape it in.

My current ideas are, using 1"x1" wood, and fastening it to make a series
of
steps, X's or triangular shaped ridges /\/\/\/\/\ in some fashion, cap on
both ends, and pour the lead into the valleys, and cool, extract, lay on
sheet of "_____________" to resist sticking, and heat in oven till a temp
that allows the metal to be mallable. Use rolling pin to flatten, and
orient them to the same size, cut off the ends, and shape as needed...

As you can see, I've got the idea worked out but need the blank filled
in..
Also, if you can help make the mold, or improve upon it, I'll make some
strips for you too... btw, I've got 40lbs of lead...

is that better??

references? i work in the stained glass industry. it's pretty commonly known
that almost all lead is ingested or inhaled. osha doesn't require gloves
when working with lead, although they do require, in certain cases,
respirators.

in actuality, the only reference to skin in the osha regulation is because
of possible skin irritation and not absorption.

Sorry, but it is a fact that lead is absorbed through unbroken skin.
In the same manner as a patch for smoking.

Although, I don't have a wimis data sheet on me.

From http://www.osha.gov/SLTC/lead/

"Most exposures occur with inorganic lead. Organic (tetraethyl and
tetramethyl) lead, which was added to gasoline up until the late
1970s, is not commonly encountered. Organic forms may be absorbed
through the skin, while inorganic forms cannot."

However the ERP says recent research indicates that inorganic lead may
be absorbed thru the skin. They do not list references though.

See this page under Dermal Absorption:
http://www.epa.nsw.gov.au/leadsafe/leadinf3.htm

Further, this article from the "Journal of the Australasian College of
Nutritional & Environmental Medicine, Vol. 15, No. 2, December 1996,
pages 11-12." shows that inorganic lead can be absorbed through the
skin, and even worse, lead absorbed this way may not show up in the
blood:
"By applying solutions of the stable lead isotope Pb-204 to the skin
of volunteers and measuring the increase in Pb-204 in blood, we were
able to show that skin-absorbed lead has a very short residence time
in blood3. The ability of lead salts to enter the body through the
skin without significantly raising blood lead has important
implications for occupational health control, because measurement of
lead in blood is the prime technique for monitoring lead exposure.
Surveys of workers in lead industries such as lead battery manufacture
showed that many of them had very high levels of lead in sweat, even
those who had retired or who had been away on leave for several
weeks1. Workers in lead industries often wear masks to avoid
inhalation of lead, but rarely have skin protection. Some lead battery
workers have their skin covered with a layer of finely powdered
lead/metal oxide1. Both lead metal and lead oxide were found to
dissolve in sweat and pass through the skin1-3."

The full article is he
http://www.acnem.org/journal/15-2_de...on_of_lead.htm

I always thought the main danger from handling lead is that particles
that adhere to the skin may be ingested or inhaled by touching the
mouth or nose, or via transfer to a cigarette, then inhaled. Looks
like we may have to re-think that.

I think he has a supply of lead-tin alloy and an interest in utilizing
it. If all he really needed was lead weight for plants, I'd send him
some. I buy it in 10 lb spools and give it away at work. Making your
own sounds like much more fun ;~)
