Compatibility
We recognize that compatibility standards are set for us by our competitors and already widely used commercial batches. There is no point in being in our own universe. Trident seal tests2 with Gaffer® batch, melted under controlled time and temperature conditions, show zero strain with Spruce Pine 87 and East Bay Regular for instance.
We have melted this glass at 1400oC (2550oF) for eight hours after the last load (compared to the standard melt temperature/time of 1310oC/2400oF for six hours) and have lowered its COE by only around 0.5 points, showing that it is a forgiving glass re volatization. It shows very little drift after a week at working temperatures, perhaps ½ a point at most.
