jmhlsy Posted September 8, 2013 Share Posted September 8, 2013 I am sure it has been told somewhere on here, but have not found it. I am building a small forge from soft firebrick encased with 3/16 plate. I was planning on lining the whole inside with SFB mortor and then coating whole inside with metricote, (thanks Wayne). Is lining it with mortor a bad idea? Or maybe just the floor? The thing I was thinking is it will be impossible to replace just one brick if I needed. What's your thoughts. Is what I planning resistant to borax? Thanks for the insight. Jason Quote Link to comment Share on other sites More sharing options...
Fatfudd Posted September 8, 2013 Share Posted September 8, 2013 Instead of fire brick for the floor get a kiln shelf and cut it to size. They seem to last real well, I've had one in a forge I've used almost daily for 2 years and It is still in good shape. Quote Link to comment Share on other sites More sharing options...
WayneCoeArtistBlacksmith Posted September 9, 2013 Share Posted September 9, 2013 You could cast the floor using Kast-0-Lite which is an insolating, light weight castable refractory which is resistant to flux. Quote Link to comment Share on other sites More sharing options...
