Borax crystals grown at low supersaturation values are described. A brief report about microtopographical studies of these crystals is presented. Growth spirals observed on almost all the habit faces except those in contact with the bottom of the nucleation cell are described and discussed. It is established that all these crystals have platelet form in the initial stages of crystallization and as growth proceeds they develop and grow by spiral mechanism. The conditions under which the screw dislocations play the role in the development and growth of the crystals have been worked out.
