Although the calculations are based on idealized assumptions, they indicate the temperatures at which sintering by viscous flow is possible. Boiler experience with ash no. 5 indicated no agglom- eration problems at typical operating temperatures. The temperature is obviously too low for any glass phase to be formed.
