Lokacin da nau'ikan nau'ikan alkali guda biyu suka kasance a cikin gilashin a lokaci guda, daidaiton sinadarai na gilashin yana da matuƙar wahala saboda "sakamakon alkali mai gauraye", wanda ya fi bayyana a cikin gilashin gubar.
A cikin gilashin silicate tare da alkaline ƙasa karfe ko wasu bivalent karfe oxide maye gurbin silicon oxygen, kuma zai iya rage sinadaran kwanciyar hankali na gilashi. Duk da haka, sakamakon raguwar kwanciyar hankali yana da rauni fiye da na alkali karfe oxides. Daga cikin divalent oxides, BaO da PbO suna da tasiri mafi ƙarfi akan kwanciyar hankali, sannan MgO da CaO suka biyo baya.
