I have three bags of refractory cement plus a bag of quickcrete I am selling for $35.
It is from an oven project that I never started.
The refractory is of a couple of different kinds and I can’t recall why I chose the ones I did. I will say it was very hard to find. Looked all over Dallas and finally had to drive to an industrial suburb to purchase it.
One of the bags is a little beat up but it has been kept dry and appears ‘OK’ although it is about a year old.
I offer a warranty in that if it turns out to be bad I’ll refund your money. I think I paid around $170 for all of this.
I’ll look at my box of stuff for this project and see if there is anything else I can throw in.
