乾隆皇帝是中国古代最爱玉的帝王。乾隆皇帝爱玉、藏玉、甚至在玉器制作上亲力亲为。历史上再没有哪位帝王能比得上乾隆皇帝对玉器的认识与研究投入如此大的精力。乾隆皇帝对玉的痴迷，促使“乾隆玉”成为中国古代玉器发展进程中最耀眼的明珠。乾隆孝粉玉碗乃是乾隆皇帝他母亲当时生病,经过御医治疗研发中药必须配合玉器使用才能达到最佳疗效。为此乾隆皇帝连夜命令工匠赶制出玉碗-玉蝶-玉杯-玉瓶等。后期被后人誉为“乾隆孝粉”。           乾隆孝粉玉碗是乾隆年间的一种玉碗，底部刻着篆字，书写“乾隆年制”，后有人误念成“乾隆孝粉”，因名字通俗易解而流传。此碗的内外部有花纹，其材质十分精美，用灯光照亮，十分通透，玉质光感强，一般来说，主要是上等白玉，是宫廷御用之物，极少流落民间。“乾隆孝粉”因选用上等白玉制成，暗刻花纹，工艺十分复杂，就算在宫廷也是稀有之物。此藏品包浆自然圆润，品相完好，工艺精美，符合当时工艺特征，具有极高的收藏投资价值和观赏价值。 英文翻译：Emperor Qianlong was the emperor who loved jade in ancient China. Emperor Qianlong loved jade, hid jade, and even worked on it himself. No other emperor in history can match the great energy invested by the emperor Qianlong in understanding and researching jadeware. Emperor Qianlong's obsession with jade made "Qianlong jade" the most dazzling pearl in the development of ancient Chinese jade. The Qianlong filial powder jade bowl was caused by Emperor Qianlong's mother who was ill at the time, and after the treatment of the Chinese medicine, the Chinese medicine must be used in conjunction with the jade to achieve the best effect. For this reason, the Emperor Qianlong ordered the craftsmen to produce jade bowls, jade butterflies, jade cups, jade bottles, etc. overnight. Later known as "Qianlong filial piety".         The Qianlong Xiaofen jade bowl was a jade bowl during the Qianlong period, with the seal characters engraved on the bottom, and the words "Qianlong year system" were written. Some people misunderstood it as "Qianlong xiaofen powder". There are patterns on the inside and outside of this bowl. The material is very exquisite, illuminated by lights, very transparent, and the jade has a strong sense of light. In general, it is mainly white jade, which is used by the palace and rarely hangs in the folk. "Qianlong filial powder" is made of fine white jade, with dark engraving patterns, and the process is very complicated, even in the palace. This collection has a natural rounded pulp, intact appearance, exquisite craftsmanship, which is in line with the characteristics of the craftsmanship at that time, and has extremely high collection investment value and ornamental value.
