TLDR
In this paper, alluminosilicate zeolites are rapidly and efficiently prepared by seeding an aqueous mixture containing alumina, silica, and alkali metal hydroxide with zeolite seeds, i.e. nucleation centers having an average size below about 0.1 micron.Abstract:

Molecular sieves and processes for their manufacture
TL;DR: Mixtures of synthesis mixtures of different alkalinity's produce small MFI crystals that are not spherical as mentioned in this paper. But they do not have the ability to synthesize their own MFI.

Process for preparing high silica faujasite
TL;DR: In this article, a process for pre-preparing a fertalite site with a SILICAALUMINA RATIO of about 4.5 by treating a mixture of CLAY, ALKALI METAL HYDROXIDE, and NUCLEATION CENTERS (ZEOLITE SEEDS) and heating to convert to the ZEOLITE DESIRED is described.
Patent
Preparation of high-silica faujasite
TL;DR: Faujasite having a silica to alumina molar ratio greater than 4 is prepared by forming a reaction mixture having specified proportions of Na2O, Al2O3, SiO2 and H2O using as reactants solutions of sodium silicate, sodium aluminate, and an aluminum salt to provide a proportion of the alumina, and crystallizing the reaction mixture in the presence of nucleation centers (zeolitic seeds) Suitable aluminum salts are aluminum sulfate, chloride and nitrate as discussed by the authors.
