I'd like information on where to get materials at a good price. I live between Madison and Fond du lac. Just the regular materials I'll need like sodium silicate, lincoln 60 fireclay, premade firebricks, perlite.
I understand I need play sand instead of river sand.
And what type of perlite do I ask for? I understand that the agricultural type is not what is wanted.
I'll probably end up using just regular clay for everything.
Any information would be appreciated.
