The main borate deposits of Turkey are located in the area between Balıkesir and Kütahya Provinces. The chemical analysis of the hydroboracite samples collected from Günevi mine of the Bigadiç-Yolbaşı area and the loss of water recorded at higher temperatures were studied. The samples were further examined under the microscope and by X-ray diffraction methods. Studies carried out to date indicate that no intermediate compounds, containing relatively small amounts of crystal water, compared to the original mineral, were observed as a result of heating the hydroboracite samples to higher temperatures. Based on the Mohs' scale of hardness, the hardness of hydroboracite mineral discovered in Turkey wes determined to be more than 5 and less than 6. Dana, however, states that the hardness of hydroboracite mineral ranges
between 2 to 3. The DTA curve of the hydroboracite mineral discovered in Yolbaşı reveals the major macro properties of this mineral.
Türkiye'de, Balıkesir-Kütahya illeri arasındaki bölgede önemli bor mineralleri yatakları vardır. BigadiçYolbaşı Büyük Günevi ocağında hidroborasit mineralinin kimyasal analizi, temperatürle su kaybı tespit edildi. Kızdırma temperatürlerinde ele geçen numuneler ayrıca mikroskop ve X-ray difraksiyon ile incelendi. Böylece, hidroborasitin çeşitli temperatürlerde kızdırılması ile tabiî kimyasal bileşimine göre daha az kristal suyu ihtiva eden ara bileşiklerinin teşekkül etmediği görüldü. Türkiye'de bulunan hidroborasitin Mohs sertlik cetveline göre 5 ten büyük 6 dan küçük olduğu tespit edildi. Halbuki Dana'ya göre hidroborasit mineralinin sertliğinin 2-3 arası olduğu kayıtlıdır. DTA eğrisi de çizilmek suretiyle, Yolbaşı'nda bulunan hidroborasitin göze batan makro özellikleri açıklandı.
