A beginner's question, "If you wanted to attempt some small pieces of Forge Welding, and you have heard that the use of Borax with destroy the bottom of your Forge, what do you do to protect the inside of the Forge" ?

Flux will eat up the ceramic blanket.  You should not run a forge with exposed ceramic blanket anyway, unless you want cancer.  Kast-0-Lite is a castable refractory to be cast over the ceramic blanket and is resistant to flux.  If you are getting a build up of flux in the floor of your forge you are using to much flux.
Check out the Build a Gas Forge on the Forge Supplies page at http://www.WayneCoeArtistBlacksmith.com and the other attachments there.

Let me know if I can help you.

I use RAM, it's a plastic refractory used in industrial burners.  I'm just using the blue ram, green is even better.  Since I do a lot of cable, and it's messy I'd have to rebuild my forge at least once a year if not more.  With the ram, I have to rebuild, not because it got ate up but because of buildup.  RAM's some tough stuff.

Rule #10;  "I can make that" translates to; "I'm to cheap to buy it new."

Thanks to all for your input !

I am not sure IF I will ever get there but I appreciate the input !

The Half Brick idea sound like a quick solution and you can watch the break down of the brick and replace as necessary.

I have found kiln shelving to hold up well against borax. It gets a bit goey for a short time, but it hardens up. It doesn't last forever, but I haven't had to replace mine yet.
If you go to a local pottery supply store, they should have some cuts or broken pieces that they will probably be willing to part with at a clearance price. They come in different temperature ratings, alumina content, and other things, but pretty much any of the higher rated ones should work. Ask them for specifics.

Don't use so much flux.  You just need enough to coat the metal and run between the layers.  Flux at a lower temp (just beginning to glow) to reduce scaling.  You might want to look into building a Ribbon Burner forge for a more even heat.  Check out the Ribbon Burner attachments and the Build a Gas Forge attachment on the Forge Supplies page at http://www.WayneCoeArtistBlacksmith.com.  I weld in my Ribbon Burner forge with no flux.  Get a pyrometer and shoot for 2015 degrees F

Casting the interior of the forge with Kast-0-Lite is a good product to use.  Though it will not prevent flux buildup it is resistant to the corrosive effects of the flux.
