To crack cast iron, temperatures generally need to exceed 1,200°F (about 650°C). At this high temperature, the material becomes more brittle and susceptible to thermal stress. Rapid cooling or thermal shock can also induce cracking, even at lower temperatures, if the cast iron has been heated unevenly. It's essential to handle cast iron carefully during heating and cooling to prevent such damage.
The miracle cure is called JB Weld. I swear to you, you have or will never find a product with so many used, except for maybe duct tape. It works on cast iron, engine blocks, car exaust pipes and many more things you can imagine. See the related link for more information.
You can paint about anything. Depending on the temperature the iron is getting will say what type of paint you need. (there is special paint for engines) if the iron is going to get extremely hot, you might not find a sutable paint.
If the pipe is No Hub cast Iron you can use a mission cap If the cast Iron is bell then you caulk in a cast iron plug If the cast iron is a spigot end you get a transition coupling either standard weight CI or extra heavy and then use a cast iron cap in the transition coupling

Cast iron is, as the name implies, "iron" which has been "cast", or melted and poured into a mold. The material is usually not really pure iron but rather an alloy including carbon and (often) silicon.
They are iron, so with enough heat, they will melt. Because of the nature of cast iron, they will probably crack and break before they melt.
Cast iron can reach temperatures of up to 2,200 degrees Fahrenheit before it reaches its maximum temperature.
The danger in using cast iron cookware on a smooth, glass top electric stove is that the cast iron may cause the glass surface to crack. However, plenty of people have reported that they've used their cast iron cookware on glass top stoves with no issues.
As far as i know, coolant is not required while machining cast iron because, carbon in cast iron is present in the form of graphite (which is a cooling agent - self cooling). Moreover the carbon content is high in cast iron.
Enameled cast iron cookware has a porcelain coating that prevents rust and eliminates the need for seasoning, while traditional cast iron cookware requires seasoning to prevent rust and maintain a non-stick surface. Enameled cast iron is easier to clean and maintain, but it is not as durable as traditional cast iron and may chip or crack over time. Traditional cast iron cookware is known for its ability to retain and distribute heat evenly, while enameled cast iron may have slightly different cooking properties due to the coating.
Hello I found this answer to the question... "How much oakum is required in 6 inch cast iron pipe before lead is poured into it?" From the Cast Iron Soil Pipe Association http://www.cispi.org/handbook/chapter4.pdf http://www.cispi.org/ Hope,this helps...
To protect your glass top stove from damage when using cast iron cookware, make sure the bottom of the cookware is smooth and flat to prevent scratching. Avoid dragging the cookware across the surface and lift it instead. Also, be cautious of sudden temperature changes, as extreme heat can crack the glass.

Iron melts at a temperature of around 2,800 degrees Fahrenheit (1,538 degrees Celsius). This high temperature is required to break the strong metallic bonds that hold the iron atoms together in a solid state, allowing them to move freely as a liquid.
No PVC is acceptable, you can join the new PVC piping into the existing Cast Iron.
