principle and process of producing potassium-nitrogen compound fertilizer and aluminium hydroxide from potash alum are studied. Some problems are solved through the pilot test.───钾岩石制得的钾明矾进一步制备硫酸型钾氮肥和氢氧化铝，从原理、工艺等方面进行探讨，并通过中试解决了工业化生产所出现的问题。
In potash it turns black, but in alum nothing happens until you bring it to the boil, then purple colour comes flooding out.───在碳酸钾中，它变成黑色，而在明矾中一开始却什么反应都没有，直到煮沸后紫色都溢出来了。
Spence's product was an ammonium alum which gradually displaced the potash alum which had been made principally at Whitby.
