THE RESEARCHESOF VOTIVE BOAT PICTURE TABLETS TO MAKE HISTORICAL INVESTIGATION AND RESTORE PAINTING BASED ON SKILL OF PAINTING

我们对243块船画碑进行了调查，结果表明：船画碑的支撑物大多为木板，而自1834年以来一直沿用的牌子上都有纸质的支撑物。我们首先在1848年的专用粉底上发现了使用印刷纸的情况。我们发现了三种粉底：黄色鸵鸟粉底(Oudo)、粉笔粉底(GoFun)和无粉底。最初，我们在1789年推出的平板电脑上发现了粉笔基金会。另一方面，自1846年以来，我们再也没有发现过黄色的鸵鸟粉底。1752年至1863年的供碑上绘制了青黛(Ai)，1862年的供碑上首次发现了复合天青石(Gousei-Gunjyo)。我们可以在云、住友神社和太阳等图片的背景中找到独特之处。在1750年至1788年的献礼碑上，画着奇特的云彩。它们是使用红铅(Tan)、氧化铁红(Bengara)、草木多里(Kusamidori)和粉笔的设计。在1772年至1878年的碑刻中，我们发现太阳被涂在空气中，但在1868年以后的碑刻上，太阳几乎被画在地平线上。我们发现，在滕堡时期(1830~1843)以前的碑刻上，铅和氧化铁红被用作红色，但自明治时期(1868~1911)以来，朱砂(Syu)也被用作红色。我们发现，黄色是黄色的，但在天普时期(1830~1843年)以前的碑刻上，红色是铅红和氧化铁红和甘博格(头像)在打印图片时用作黄色。
