Schoolcraft Blast Furnace
Pictured Rocks National Lakeshore Schoolcraft National Park Service U.S. Department of the Interior Blast Furnace Schoolcraft furnace With surveyor William Burt’s discovery of iron ore near Teal Lake in Marquette County in 1844, Michigan’s Upper Peninsula suddenly became a hub of activity. The discovery led to construction of a vast mining and manufacturing industry using forges and blast furnaces. When the Civil War ended, many of the South’s furnaces had been destroyed by the war. Westward expansion was occurring across the plains and demand for iron boomed. It was during this era that many of the Upper Peninsula’s furnaces were constructed. There were advantages to smelting iron ore from charcoal fires. Iron produced in this manner was low in carbon content, making it highly fusable, strong, malleable and able to withstand shocks without cracking. The iron made fine wagon rims, horseshoes, and railroad wheels. Before the boom times were over, 29 separate furnaces were located on the Old Munising, ca. 1870 peninsula, though not all operated simultaneously. The business of iron making required more capital than was readily available in the area and financing and management of the operations was often complex. The first group of investors were from Philadelphia. They wished to develop a resort village on Munising Bay’s east shoreline in 1850. Some 87,000 acres of timber were purchased for $.85 an acre. A village was platted on the east shore of Munising Bay, lots were sold, and a dock was built. Henry Mather and Peter White acted as agents for the group of investors who created the Schoolcraft Iron Company in 1866. -

5. Sirhowy Ironworks
Great Archaeological Sites in Blaenau Gwent 5. SIRHOWY IRONWORKS There were a number of ironworks in the area now covered by Blaenau Gwent County Borough, which provided all the raw materials they needed – iron ore, limestone and fuel, charcoal at first but later coal to make coke. The Sirhowy ironworks (SO14301010) are the only one where there is still something to see. The works were opened in 1778 with one blast furnace. Although it was originally blown by water power, in 1799 the owners invested in a Boulton and Watt steam engine. This gave them enough power to blow a second furnace, which started production in 1802. In the early years of the 19th century, the pig iron produced at Sirhowy was sent to the Tredegar works a little further down the valley where it was refined, until 1818 when the Sirhowy works were sold and started to send its pig iron to Ebbw Vale. A third furnace was added in 1826 and a fourth in 1839. But by the 1870s iron smelting at Sirhowy was no longer profitable, and the works finally closed in 1882. Like all ironworks in South Wales, the furnaces were built against a steep bank which enabled the ironworkers to load the charge of iron ore, limestone and coke or charcoal fuel more easily at the top of the furnace. All that is now left now are the remains of a bank of blast furnaces with the arches that would originally have linked them to the casting houses in front, and the building that originally housed the waterwheel. -

Bloomery Design
Arch ‘n Craft Practicum- Week 4 BLOOMERY DESIGN Hiu, Julieta, Matthew, Nicholas 7 3/4" The Stack: 3 3/4" In our ideal model we would use refractory bricks, either rectangular bricks or curved bricks which would help us make a circular 1'-8" stack. The stack would be around 3 feet tall with a 1 foot diameter for the inner wall of the stack. There will be openings about 3 brick lengths up(6-9 inches) from the ground on 1'-0" opposite ends of the stack. Attached to these openings will be our tuyeres which in turn will connect to our air sources. Building a circular stack would be beneficial to the type of air distribution we want to create within our furnace; using two angled tuyeres we would like air to move clockwise and counterclock- Bloomery Plan wise. We would like to line the inside of the stack with clay to provide further insulation. Refractory bricks would be an ideal material to use because the minerals they are com- posed of do not change chemically when 1'-0" exposed to high heat, some examples of these materials are aluminum, manganese, silica and zirconium. Other comments: 3'-0" Although we have opted to use refractory bricks, which would be practical for our intended purpose, we briefly considered using Vycor glass which can withstand high tem- peratures of up to 900 degrees celsius or approximately 1652 degrees Fahrenheit, which Tuyere height: Pitched -10from horizontal 7" would be enough for our purposes. Bloomery Section Ore/ Charcoal: Our group has decided to use Magnetite ore along with charcoal for the smelt. -
Assessment of Public Comment on Draft Trout Stream Management Plan
Assessment of public comments on draft New York State Trout Stream Management Plan OCTOBER 27, 2020 Andrew M. Cuomo, Governor | Basil Seggos, Commissioner A draft of the Fisheries Management Plan for Inland Trout Streams in New York State (Plan) was released for public review on May 26, 2020 with the comment period extending through June 25, 2020. Public comment was solicited through a variety of avenues including: • a posting of the statewide public comment period in the Environmental Notice Bulletin (ENB), • a DEC news release distributed statewide, • an announcement distributed to all e-mail addresses provided by participants at the 2017 and 2019 public meetings on trout stream management described on page 11 of the Plan [353 recipients, 181 unique opens (58%)], and • an announcement distributed to all subscribers to the DEC Delivers Freshwater Fishing and Boating Group [138,122 recipients, 34,944 unique opens (26%)]. A total of 489 public comments were received through e-mail or letters (Appendix A, numbered 1-277 and 300-511). 471 of these comments conveyed specific concerns, recommendations or endorsements; the other 18 comments were general statements or pertained to issues outside the scope of the plan. General themes to recurring comments were identified (22 total themes), and responses to these are included below. These themes only embrace recommendations or comments of concern. Comments that represent favorable and supportive views are not included in this assessment. Duplicate comment source numbers associated with a numbered theme reflect comments on subtopics within the general theme. Theme #1 The statewide catch and release (artificial lures only) season proposed to run from October 16 through March 31 poses a risk to the sustainability of wild trout populations and the quality of the fisheries they support that is either wholly unacceptable or of great concern, particularly in some areas of the state; notably Delaware/Catskill waters. -
