二、砂硼砂埋藏干制法用细砂制作干花,在欧洲已有几百年的历史了。这种方法简单说就是把花枝置于容器内,然后灌满干细砂,并敞开容器上口,以加快空气的流通和水分的蒸发。细砂在这里并不是用来吸收花瓣中水分的(即不用作干燥剂),而是为了让花朵在蒸发水分时,保持生长时的姿态。干燥所需时间通常是3—5周。具体要多久,还要看花瓣的厚薄、瓣数的多少及气温和湿度条件等。 Second, sand borax buried dry method of making dried flowers with fine sand, in Europe has been hundreds of years of history. This method is simply to put the squid in the container, and then filled with fine sand, and open the upper container to speed up the flow of air and water evaporation. The fine sand here is not used to absorb the water in the petals (ie, not used as a desiccant), but rather to keep the flowers in a state of growing while the water evaporates. The drying time is usually 3-5 weeks. Specific how long, but also depends on the thickness of the petals, the number of flap number and temperature and humidity conditions.
