About 25 parts by weight of furfural and about 3 parts by weight of sodium hydroxide granules are added to the said phenol silicate, mixed then heated to just below the boiling point of furfural for 10 to 50 minutes until the desired viscosity is obtained, thereby producing brown poly(furfural phenol silicate) resin. The said resin may be produced as a thick brown liquid, brown fusable solid, or infusable solid, depending on the length of time that the resin is heated.
