A gunnable plastic refractory is made by adding a polysaccharide ether such as methylcellulose to the refractory composition and adjusting the moisture content to be from about 4% to about 10%. The workability index of the refractory mix is from about 8% to about 30%. The refractory is gunned without stoppages caused by clogging of hoses and the rebound rate is low.
