Aluminosilicate microcrystalline glass, and a manufacturing method and a product thereof, where in addition to a glass phase, the aluminosilicate microcrystalline glass includes principal crystalline phases: a magnesium aluminate (MgAl2O4) crystal including a volume percentage of 5% to 30%, a lithium disilicate (Li2Si2O5) crystal including a volume percentage of 10% to 30%, and a quartz and quartz solid solution including a volume percentage of 5% to 30%. Residues are other inevitable impurities. The inevitable impurities include intermediate products generated when the MgAl2O4 crystal, the Li2Si2O5 crystal, or the quartz and quartz solid solution is being generated, other impurities that are inevitable in a glass production process, and the like.
