Abstract
Disclosed is a decorative, non-combustible, synthetic fire-log for use in a gas or oil burning fireplace or stove. This synthetic fire-log has a density ranging from 15 to 45 lb/pi.sup.3. It is made by pouring a mineral foam into a mold shaped as a natural wood-log and letting this foam harden in the mold to form the synthetic fire-log prior to unmolding the same and letting it dry. The foam that is used for such a molding comprises 1 part by weight of a solution of phosphoric acid in which polyvinyl alcohol is dissolved in such an amount as to make the solution viscous; from 0.03 to 6 parts by weight of wollastonite containing from 0.5 to 4% by weight of a carbonate salt; from 0.2 to 10 parts by weight of water optionally one or more pigments to give a natural wood-like aspect to the synthetic fire-log; and, optionally also, a small amount of reinforcing glass fibers. The synthetic fire-log that is so-obtained looks like a natural wood-log and has the same glowing aspect in use. Moreover, it does not generate soot and advantageously ensures a full combustion of the gas or oil mixture fed into the fireplace or stove, thereby resulting in a substantial reduction in the amount of carbon monoxide released in the atmosphere.
