    三成分系に於ける組成と性質との關係は三角座標によりて圖示せらる。著者は三成分系の状態圖或は所要の性質を代表する圖形を組成百分率を以て表示する一方法を論じたり。
    即三角形内に於ける直線形及二次曲線を表現すべき夫々の方程式を解析的に求めその應用を説明せり。

    The following are the studies made with an influence of sodium nitrate or potassium nitrate is added into a glass batch as an oxidizing agent.
    (A) A study has been made as to respective colours of glasses and the state of oxidation of iron oxide in cases where sodium nitrate have been added increasing amounts there of from 0.5% to 6.0%, into respective batches of soda-lime-iron oxide silica glass in which the content of iron oxide being 2% and the content of soda being constant.
    (1) It has been noted that the colour of the glass become slightly yellowish as the amount of sodium nitrate added is increased, and no change has been seen in the content of FeO in the glass, and in consequence there of the percentage ratio of FeO/FeO+Fe2O3 has been found constant.
    (2) Next, the transmission curves has been studied of respective glasses by glass specimens having thickness of about 1mm. polished on both sides, and it has been founds that there is no difference in the form of curves and the limit of shortest wave length to be transmitted.
    (3) When melted glass batches of same composition it has shown that the percentage ratio of FeO/FeO+Fe2O3 in a batch without being added with sodium nitrate is a little higher than that which being added with sodium nitrate, and the color of the former is relatively greenish.
    (B) A study has been likewise made about glasses in which the alkali content is so kept as to be always 16% and one percent of wich come from sodium nitrate or potassium nitrate and also the lime content of the said glass composition being one by one replaced with ferric oxide, by using soda ash and chili nitre or potash and nitre as raw materials for alkali in such glass batches whose base glasses would be composed of 72% SiO2, 12% CaO, and 16% Na2O, 72% SiO2, 12% CaO and 16% K2O.
    The following is the results:-
    (1) The amounts of FeO and Fe2O3 contained in the glasses and the percentage ratio for FeO/FeO+Fe2O3 are as in the following table:
    (2) As to the colour of the glasses, in case of of soda glass having a definite amount of chili nitre contained in batches it has been seen that yellowish green is dominating as iron oxide content increases. In case of potash glasses having a given amount of nitre in batches, greenish yellow colour has been strengthened as the iron oxide content increases. And in both glass series the colour have been found more yellowish and clearer than cases where batches have been melted without adding thereto any oxidizing agent.
    (3) Compared the percentage ratio of FeO/FeO+Fe2O3 between the glasses melted by adding oxidizing agent and one melted by without adding the same agent. It has been found that the difhence is considerably small in case iron content is very small but the difference grows larger as the said content increases.
    (4) Finally the transmission curves of such glasses have been determined. As comparing with those melted without adding into batches oxidizing agent the transmission are generally higher but there is found no diffreence between the said two glasses in the limit of wave lengthes which transmit.

    The author studied on the dulabilities of chrome-green and carbon-brown glasses. The results were summerised as followed:
    Green glasses, which were coloured by minute quantities of chrome oxide or other chrome salts, and brown glasses, which were coloured by carbon, showed the better dulabilities than those which were prepared from the batches of the same compositions except colouring materials as fomer.
    Tnese phenomena were considered to be caused by neither volatilisation of alkalies nor other changes of glass-compositions. Because the analysis of the above mentioned coloured and no colour glasses showed that the compositions of those glasses were regarded to be the same.

    1 蝋石質不燒煉瓦の製造法に就て實驗した。多數の豫備實驗の後蝋石80と蝋石粘土20及蝋石93と木節粘土7の配合物に膠, カゼイン, 水ガラス等の結合劑の適量を添加して約100kg/cm2又は以上の耐壓力を有し, 耐火度は殆ど主原料と變らず, 能く急變に耐え而も加熱に依て著しく收縮せざる不燒煉瓦を得た。
    2 乾燥品の耐壓力を約100kg/cm2又は以上にするには蝋石及粘土の重量100に對し, 膠は3-4以上, カゼインは2-3以上, 水ガラスは5以上, 又は是等の適量混合物の添加を必要とした。
    3 乾燥品を高温度に急熱した後の耐壓力は案外高かつた。然るに800℃, 850℃の如き低温度に急熱するか或は520℃の如き低温度まで徐熱したものの耐壓力は甚だ低かつた。但し膠の凝固劑として重クロム酸カリを用ゐた場合には稍強く, 水ガラス2以上を添加したものは100kg/cm2以上の耐壓力を示した。
    終りに臨み不燒蝋石煉瓦の製造に着想し且本研究の原料を寄贈せられた牧位眞治氏に對して敬意と謝意とを表する次第である。
