1. A method of synthesizing an aluminosilicate zeolite with a silica-to-alumina molar ratio (SAR) of 10 or greater, comprising:
forming a reaction mixture comprising at least one alumina source, at least one silica source, and at least one organic structure directing agent, wherein the reaction mixture has a solids content of about 10% or greater, and H2O/SiO2 molar ratio of the reaction mixture is about 15 or less; and
crystallizing the reaction mixture at a temperature of about 100° C. or less in an open vessel open to an atmosphere at atmospheric pressure to form the aluminosilicate zeolite;
wherein the at least one alumina source comprises a zeolite with an FAU, LTL, LTA, or MOR crystalline framework.
