Bab 155: First step in trying to make glass and steel

In the afternoon Einar, who was looking at the forge with his ski goggles, was trying to make some red and sandy stones start to melt.

This because he was thinking of making the first refractory bricks to build a furnace to create glass.

"Seren, you can wipe the sweat from my forehead, if it keeps accumulating it could fog up the glasses."

Seren who was next to him used a linen cloth to wipe the sweat from Einar's forehead.

"To think that the red stone where we get the iron ore can work to make glass and what you call steel.

But how could you find the information on that, did Odin tell you? "

Einar smiled nervously and nodded his head "It was something like that ..."

'Although the truth is just that I did not remember that bauxite also had aluminum ore, so in theory, if it melts with sand it could create a firebrick.
