Ringwood's Iron Industry
By Jack Chard
ORIGINS
OF THE IRON INDUSTRY
Ironmaking in
the Ringwood area had its beginnings in 1736, when Cornelius Board, and
Englishman of Welsh descent, was prospecting for precious metals.
He discovered instead the local magnetite iron ore.
With his partner, Timothy Ward, he purchased land and built a bloomery at
what is now known as Sterling Lake, about five miles north of Ringwood.
In 1740 Board sold his interest in the Sterling ironworks and moved to
what is not the Ringwood area, where he bought land from the Proprietors of East
Jersey and erected a forge. Less
than two months after buying the land, he sold acres to the Ogden family of
Newark, New Jersey. One wonders
whether a family connection was involved. The
Ogdens also purchased land from the Proprietors, formed the Ringwood Company in
1742 and built the first blast furnace in the area.
In 1762 the
Ogdens built a new blast furnace. In
1764, however, the works were offered for sale by advertisement in the "New
York Mercury" of March 5, 1974.
The next
character on the scene was the remarkable Peter Hasenclever.
Born in Remscheid, Germany, in 1716, he worked as a boy in the local
ironworks, but later became a traveling salesman of cloth and needles and
established a business at Cadiz, Spain. In
1763 he went to England and became a British citizen.
Although he had not visited America, he was sure of the tremendous
potential of the New World. He
formed a partnership (Hasenclever, Seton, and Crofts) with a capital of 20,000
pounds sterling and in April 1764 sailed for New York, arriving six weeks later.
It seems he had learned that the Ringwood Ironworks was for sale; he
purchased it July 5, 1764, and proceeded energetically to repair and improve it.
Before leaving
Europe, Hasenclever had contracted with a large number of skilled German
ironworkers to bring them and their families to America.
The more than five hundred people involved in this ambitious operation
started to arrive in the autumn of 1764. Meanwhile,
Hasenclever had bought 122 horses, 214 draft oxen, 51 cows, and a "vast
number of implements for the works". With
great energy and remarkable organizational ability, Hasenclever within two years
established four blast furnaces (in Ringwood, and also at Charlottenburg, Long
Pond, and Cortlandt – all within about 20 miles of Ringwood), seven forges,
two stamping mills, all the necessary waterwheel systems, charcoal houses, and
all the necessary buildings for housing the workers and animals.
He constructed a network of roads, with bridges connecting the plants and
supporting sawmills and carpenters' shops.
A tremendous investment! But
the winter of 1765 brought great floods and washed out many of the dams, which
had to be rebuilt. The German
ironworkers demanded more money. A
shipment of iron from Ringwood received high praise in England, but expected
large profits did not materialize. However,
the foundations of a large and potentially efficient enterprise had been laid.
In addition to
his ironmaking projects, Hasenclever had also purchased large tracts of land for
proposing hemp, flax, and madder plantations.
In 1766 Hasenclever
heard disturbing reports that one of his partners, Andrew Seton, had
been indulging in a spending spree, apparently using the partnership money.
In November, Hasenclever returned to England to investigate.
He found that some new and influential partners had become involved, in
expectation of substantial profits. Hasenclever
appears to have convinced them of the soundness of the enterprise and his
actions, and a new deed of partnership was drawn up, appointing him manager of
the American operations. He set
sail on June 1, 1767, arriving two months later in New York.
Forty-six days later, a Jeston Humfray arrived from London with orders to
supersede Hasenclever and take over management of all the properties.
This was a terrible blow. In
Hasenclever's own words: "This
clandestine maneuver does little honor to the discernment of the trustees, as
they had engaged a man for the conducting of such important affairs without
informing themselves about his abilities or character – a man who had never
managed ironworks and was utterly ignorant of his business."
In December he received a letter from the company, ordering him to send
back his books, suspending him, and repudiating debts he had incurred in the
name of the company. Again, in
Hasenclever's own words: "This
was…a premeditated deceit – a plot which they had formed before they signed
the deed of partnership with me…They acknowledge (in their petitions in
Chancery) that they make this deed of partnership that I might return to America
and assign the lands and estates to them, which I never refused to do."
There seems no
doubt that Hasenclever was treated very badly.
He returned to England and years of legal proceedings ensued, in which
were included, to Hasenclever's disadvantage, indications of some very
questionable activity. Finally, in despair, he left London in 1773 to return to
Germany, where Frederick the Great gave him the assignment of reorganizing the
linen industry, in which project he appears to have been very successful.
He died June 13, 1793. Less
than seven months later, the long, drawn-out legal proceedings in England ended
with a decision in his favor, awarding heavy damages.
Unfortunately, the American company was in bankruptcy, and there was no
money to collect.
Hasenclever was
highly respected by his contemporaries in America.
At the time of his recall by the company he asked the Royal Governor to
appoint a commission of important ironmasters and industrialists to inspect the
ironworks he had established. The
report was highly favorable to Hasenclever, stressing the technical innovations
and efficient operation. There
seems no doubt that he received outrageous treatment from his partners. In justification of his conduct, he published in England an
account of his activities in America, entitled "The Remarkable Case of
Peter Hasenclever, Merchant". This
1773 book was reproduced in facsimile by the North Jersey Highlands Historical
Society in 1970, with a brief introduction and map. Hasenclever had the vision and energy of a great
industrialist. It is tragic that he
was not able to complete the undertaking he started so well.
The company,
still concerned about getting returns from its large American investment, in
1770 engaged Robert Erskine, F.R.S., to take over management and report what
should be done with the property. Although
no ironmaster, Erskine was a well-regarded engineer who had been granted a
patent for a new type of pump. His
election to the prestigious Royal Society as "a gentleman well versed in
mathematics and Practical Mechanics" speaks well for his abilities.
He spent some months visiting ironworks in England to acquire some
practical knowledge of the art and practice of ironmaking.
On arrival in Ringwood in June 1771, he found the works under the
direction of an experienced ironmaster, John Jacob Faesch, one of Hasenclever's
men. They were supposed to run the
works jointly, but as would be expected, friction developed, and in the
following year Faesch left to set up his own ironworks, at Mount Hope.
Erskine's
recommendation to the company was to sell the works, but there were no takers.
Meanwhile, events were leading up to the American Revolution.
Erskine's sympathies were with the colonists, and he warned in letters
that the policy of the government in England would inevitably lead to a break.
In 1775 he raised a company of militia from his workmen, with prime
responsibility of defending the works. When
war came, he supplied iron the Revolutionary army.
However, his request for deferment of his men from military duty was
turned down, and he soon lost many of them.
By the end of 1777 iron production had ceased.
Among his
accomplishments, Erskine had surveying skills.
At the request of George Washington he was appointed Geographer and
Surveyor-General to the Continental Army on July 27, 1777.
Throughout the war he provided invaluable service in making maps of the
areas involved in hostilities. After
a mapping trip in the autumn of 1780, he developed "a severe cold" and
died two weeks later. He is buried
in the cemetery at Ringwood Manor.
After the end
of the Revolutionary War, the Ringwood estate passed through a number of hands
but apparently was not operated as an ironworks until it was bought in March
1807 by Martin Ryerson, who already owned and operated the Pompton Ironworks,
about ten miles south of Ringwood. Under
Ryerson the works prospered, but soon after his death in 1839 his sons were in
debt and the property was up for sale by the sheriff.
Finally, in 1853, Ringwood was bought by Peter Cooper as a source of iron
ore for the Phillipsburg blast furnaces of his Trenton Iron Company.
The purchase was negotiated by Abram Hewitt, business partner of Peter
Cooper's son Edward, and manager with the latter of the Trenton works.
Abram and Amelia took a fancy to Ringwood and decided to make it their
summer home. The original manor
house (iron master's house) had been pulled down by Martin Ryerson and a small
"modern" house built in about 1810.
The Hewitts extended this house and moved into it in 1857.
The house was again enlarged in 1878, forming the elegant Victorian
country house that can be seen and visited today. The blast furnace at Ringwood was never run again after the
Ryerson period, and the remains were in due course tidied away as part of the
landscaping for the new house.
The Ringwood
estate had been purchased primarily for its iron mines.
However, with the pressure for iron during the American Civil War, two
blast furnaces were built at the Long Pond site, about five miles away.
But by the end of the war, the economic advantages of cheaper raw
materials in the Pittsburgh area forced the closing of all the eastern furnaces.
The Long Pond furnace went out of blast on May 28, 1880, ending the long
history of ironmaking in the Ringwood area.
The ruins of the bases of the furnaces remain, with the skeletons of the
old waterwheels. Nearby, the ruins
of the older, 18th century blast furnace were excavated in 1963.
All the furnaces were built of stone and all had waterwheel-powered
blowing machinery. A huge new
50-foot waterwheel was planned for Long Pond in 1873 but never completed.
Charcoal was used throughout the period until one furnace at Long Pond
was converted to anthracite coal and operated briefly on this in 1879.
The iron mines continued in operation until 1931. During World War II, the Government spent much money in restoring the Peters and Cannon mines, but peace came before they were used.
The mines were sold to private interests and changed hands several times over the next ten years. Some iron ore was shipped during this period, but in 1961 the mines were abandoned. An era closed.
THE
IRONMAKING PROCESS
Most iron ores
are oxides of iron – that is, stable compounds of iron with oxygen.
To obtain metallic iron it is necessary to remove the oxygen.
The ironmaking process depends on the fact that carbon when heated has a
great affinity for oxygen, forming carbon monoxide and carbon dioxide gas.
The earliest
method of ironmaking was the so-called bloomery process, which goes back to
prehistoric times but continued in use into the 19th century in
less-developed areas. In this
process small pieces of iron ore were mixed with charcoal (carbon) in something
very like a blacksmith's hearth. An
air blast was applied to the ignited charcoal to produce a hot fire, and the
carbon reacted with the iron oxide are to produce metallic iron and carbon
dioxide gas. (Actually the carbon formed carbon monoxide gas with the air
blast and this gas, rather than solid carbon, reduced the iron oxide.)
The temperature never became hot enough to melt the iron produced; it was
produced as a pasty mass and was pulled out of the hearth and hammered to
squeeze out as slag the charcoal and earth impurities produced form the ore.
The product was essentially carbon-free iron, soft and malleable,
although still containing some slag particles.
It was a very small-scale process, producing only a few pounds of iron in
a day's work. But the equipment was
simple and the capital investment small. By
the 18th century, waterwheels were used to operate a bellows to
provide the blast, and also to operate a tilt hammer to forge the
"blooms" produced. A
bloomery was often called a "forge".
The major
improvement in ironmaking was the invention of the blast furnace, which goes
back to the 1400's. A vertical shaft was provided over the hearth, originally
probably to preheat the incoming charge with hot gases.
The shaft, which actually had a bottle-shaped configuration, was
contained in a square stone tower about 25 feet high. The iron ore and charcoal were tipped in at the top, and
bellows produced an air blast at the bottom.
(See diagram.) In the upper
part of the shaft or stack the carbon monoxide gas reduced the iron oxide to
metallic iron, as in the bloomery; but as the iron particles worked their way
down in contact with the red-hot charcoal, they picked up about 3˝% carbon,
which dissolved in the iron. The
melting point of iron containing this amount of carbon is much lower than that
of pure iron; hence, at the bottom of the blast furnace, the carbon-containing
iron melted. It accumulated in the
"crucible" and was run out every 12 hours into channels in the sand
floor of the "casting house". A
series of parallel channels at right angles to the main channel was thought to
resemble a sow suckling her young, hence the term "pig iron".
A big advantage
of liquid iron was that it could be run into molds to form cast firebacks, pots,
and cannon. But because the high carbon content was present as flakes of
graphite running through the iron, the cast iron was brittle and could not be
forged by the blacksmith into such items as hinges and horseshoes.
To make a malleable product, it was necessary to remove the carbon.
This was done in a "finery", which was very much like a
bloomery in appearance. The pig
iron was melted in an air blast in a hearth with a charcoal fire, and the excess
carbon was in effect "burnt out" by reacting with the air blast to
form carbon monoxide and carbon dioxide gas.
As the carbon content fell, the melting point increased, so that the
final product was pasty and was removed to be hammered into a rough bar.
Again, this was essentially carbon-free iron and was therefore soft and
malleable. Needless to say, it
required skill to control this operation satisfactorily.
There was
usually a third step. The rough bar from the "finery" was reheated in a
separate hearth called a "chafery" and forged down to the required
shape and form for sale.
Usually the
blast furnace, finery, and chafery were built at some distance from one another
along a stream, for the amount of power available to work bellows and hammers by
waterwheels was limited at any one point. Further
downstream, additional heads of water would be available again for more
waterwheels.
The finery was
often referred to as a "forge". We
see reference to "a forge with four fires", that is, with four working
hearths.
Blast furnaces
were usually built against a hillside, so that the charcoal and ore could be
brought across a "chargin bridge" to the level of the top of the
furnace. A small amount of
limestone was added to help flux the impurities in the ore.
All early furnaces were open at the top, and smoke and flames rose day and night. Only well into the 19th century was the technique developed to close in the furnace and collect the gases for use as fuel in heating furnaces.
Originally,
charcoal was the only fuel used, but by the beginning of the 18th
century in Britain there was a severe fuel shortage – it required many acres
of woodlands each year to make the charcoal to keep a blast furnace going.
After many fruitless attempts, Abram Darby finally, in 1709, found a way
to use coke (partially pre-burned bituminous coal) to replace charcoal.
By the end of the 18th century, very few blast furnaces in
England were still using charcoal. But
here in America there was still plenty of wood and the fuel problem did not
become acute until later, when anthracite coal was used.
The first successful anthracite furnace operated at Stanhope, New Jersey,
in 1841. The anthracite was stronger than the charcoal and thus did
not crush as easily, so that it was possible to build the furnaces higher.
The use of coke
and anthracite required more effective blast that the old waterwheel-driven
bellows could give. The old leather bellows had been generally replaced by the
end of the 18th century by piston and cylinder devices of cast iron.
Isaac Wilkinson in England used the steam engine to work the blowing
engines. In 1757, steam power made
improved blast possible. However, in the Ringwood area waterwheels were used up to the
end of the ironmaking at Long Pond works, in 1880.
Abram Hewitt calculated that for the Long Pond site the use of
waterpower, rather than steam, saved 50 cents per ton in the cost of the iron
made.
