Yep. Silica dissolves lots of stuff at high temperatures -- in fact it even fluxes alumina to a certain extent, which is why the higher duty a refractory or firebrick is, the lower its silica content will be. (I'm not sure this is exactly related, but the term "basic" in basic oxygen furnace refers to the fact that the refractory is composed of basic oxides like magnesia. That's to distinguish them from the older furnaces with silica-based refractories. Silica is classified as an acidic oxide. Acids and bases, just like in chemistry.)

We used to use Silver sand at Hereford on mild steel. Never tried higher carbon content.
Cosira " the blacksmiths craft" Page 22 , 4 th paragraph.
but if it corrodes the forge still no point.;)
Above is mentioned the Magic "laffite plate" some of which was recently found somewhere in some dark cupboard somewhere in the UK. Gotta wonder what that stuff is.ooooo.

OK, somebody please start a thread about welding fluxes and other magic.

Going to fire a forge lined with MorocLite 30 in a little while. Guys at the refractory store recommended it for a good balance between insulating and durability.

Didn't get around to it today, but it's on the board for tomorrow. Not shown is the burner constructed from 2.5" pipe with a 1.25" opening.

Jack, I'll need to have a talk with Henry and Adrian, they made out that flux of any kind was just a crutch, of course they claimed that G&T was a mosquito repellent.

LOL they are right about the flux.
but then they tend to use sidedraft forges.;)
And they were close on the G&T. Tonic has quinine to fight malaria and Gin to stop the tonic's water killing you.:)

Everything is a crutch in blacksmithing!
If you don't use your bare fists as your hammers, a mud puddle for the anvil and heat your stock by rubbing two lengths together then you're using a crutch!
Shoot...I don't even buy stock! I wait for lightning to strike my ore pile and then take the bloom and work it between my shoulder blades while it's still hot!
