The present invention is directed to a composite artificial log for use in gas-fired artificial log fireplace assemblies or stoves, and more particularly, to a composite artificial log which has a ceramic concrete upper section molded to resemble a real log and having a relatively high thermal conductivity, which radiates a substantial amount of heat to the surroundings when heated, and a ceramic fiber lower section having a relatively low thermal conductivity, which glows visibly when heated above about 1470°F.

A composite artificial log for use in gas-fired fireplaces and stove assemblies comprising: an elongated ceramic concrete section having a surface outwardly exposed in said assemblies, said section molded to provide the appearance of a real log, said section having a cross-section constituting a substantial fraction of the cross-section of the log and a relatively high thermal conductivity for radiating heat to the surroundings when heated; and an elongated ceramic fiber section having at least one surface outwardly exposed in said assemblies, said section secured to said ceramic concrete section and having a cross-section constituting a substantial fraction of the cross-section of the log, said ceramic fiber section having a relatively high thermal conductivity which glows visibly when heated above about 1470°F.
