Few moths ago I made a furmace from junk on my main channel "Odd Tinkering" (https://www.youtube.com/watch?v=j_RWJOftX7Y). It was a very simple design and good for casting aluminum and other metals with low melting point. However I wanted to power it up so it can easily melt copper, brass and other common casting metals. I won't even try to melt iron this time because it will need some more upgrades, but making my own cast iron items would be really cool. Previously had never measured 1000 °C with the furnace and my previous attept at melting copper failed barely. This time I was able to get it to melt but it wasn't enough for proper casting the copepr would cool way too fast and it woudn't set to the bottom of my mold. In order to make the furnace hotter I have 2 options. Make my burner more powerful or to reduce the loss of heat in the process. The higher the temperature difference between the furnace and the outside, teh faster it cools down. At some point the furnace reaches the point where the heat from the burner equals the heat loss of the forge. Then the temperature stops rising and once you shut the burner the temperature cools rapidly. I decided to try to a product I found. It is called ITC 100HT. On the internet I red peoples experiences and some said the y had got their forge even 200 °C hotter with it. The product is a ceramic coating that will reflect the heat back instead of letting it escape. The coating will also help to reduce damage to the fire wool making it last longer. Because the heat is reflected back it might also help to keep the furnace hotter if I have to open the lid. A free way to support my channel is access amazon/ebay to do your regular shopping through these links. I will get a small fee from each product bought on amazon after clicking these links, whether it was the linked product or a different one.
