Abstract
Methods and systems for controlling bubble size and bubble decay rate of glass foams formed during submerged combustion melting. Flowing a molten mass of foamed glass comprising molten glass and bubbles entrained therein into an apparatus downstream of a submerged combustion melter. The downstream apparatus has a floor, a roof, and a sidewall structure connecting the floor and roof. The foamed glass has glass foam of glass foam bubbles on its top surface, and the downstream apparatus defines a space for a gaseous atmosphere above and in contact with the glass foam. The downstream apparatus includes heating components to heat or maintain temperature of the foamed glass. Adjusting composition of the atmosphere above the glass foam, and/or contacting the foam with a liquid or solid composition controls bubble size of the glass foam bubbles, and/or foam decay rate.
