A system for delivering a siliceous matrix material and selected dopants to an oxidizing reaction flame or the like. Each constituent is maintained in liquified form and transferred by means of an individually controlled metering pump to a nebulizing stage then passed to a burner or the like from which the materials are converted into appropriate soots. The soots are then applied to a starting member which is subsequently subjected to heat to fuse it into a drawing blank.

The method of forming an optical waveguide blank, comprising the steps of: providing a vapor deposition means for receiving source material vapor and directing said vapor toward a starting member; providing a starting member is proximate relation to said vapor deposition means for accumulating source material thereon; providing glass forming source materials in liquid form; delivering each of said liquids at individually controlled rates and in liquid form to a common site; thoroughly intermixing said liquids; nebulizing the intermixed liquids; delivering the nebulized, mixed liquids to said vapor deposition means and; depositing the materials in said nebulized, mixed liquids on said starting member to form said optical waveguide blank.
