After repeating several times, a layer of crystal-clear "Ice Glaze" was formed.
"This layer of Ice Glaze is crucial; it will absorb the heat before the smoke's heat can reach the fragile snow brick structure."
"The very limited heat in the smoke will mostly be consumed in sublimating this thin layer of ice, preventing any melting or dripping. This is a self-repairing design."
After completing the inner wall treatment, he carefully overturned another batch of similarly processed snow bricks on top and completely sealed the joints with snow slurry.
A smooth, heat-resistant, approximately two-meter-long sealed smoke duct was thus born.
Its end, like a silent white python, precisely extended into the foundation of the hemispherical igloo.
Now, only the final part remains—the hearth.
"A few days ago, to make the Ice Drill, I used the Triangular Hand Saw with great effort to cut out slabs from a giant Soapstone, building a small forge."
