It&#8217;s called &#8220;ultra-light&#8221; because it&#8217;s significantly lighter than traditional clay. Here are some key features and uses:<\/p>\n\n\n\n<p>1. Lightweight: Unlike traditional clay, which can be heavy and dense, ultra light clay is lightweight, making it ideal for creating delicate and intricate designs.<\/p>\n\n\n\n<p>2. Air-dry: One of the main advantages of ultra-light clay is that it air-dries, meaning it doesn&#8217;t require baking in a kiln or firing in an oven like traditional clay. This makes it convenient for crafting at home without the need for special equipment.<\/p>\n\n\n\n<p>3. Soft and pliable: Ultra light clay has a soft, pliable texture that makes it easy to mold and shape. It&#8217;s great for both beginners and experienced artists alike.<\/p>\n\n\n\n<p>4. Color options: It&#8217;s available in a wide range of colors, including primary colors as well as metallic and pastel shades. This variety allows for endless creativity in crafting projects.<\/p>\n\n\n\n<p>5. Versatile: Ultra light clay can be used for various crafting projects, including sculpting figurines, making jewelry, creating decorations, and even for educational purposes in schools and art classes.<\/p>\n\n\n\n<p>6. Non-toxic: Most brands of ultra-light clay are non-toxic, making them safe for use by children under adult supervision.<\/p>\n\n\n\n<p>7. Finishing: Once dry, ultra light clay can be painted, varnished, or embellished further to add detail and enhance the finished piece.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Preparation of PVA Glue<\/strong> <\/h2>\n\n\n\n<figure class=\"wp-block-table alignwide\"><table><tbody><tr><td>Items<\/td><td>Weight,kg<\/td><td>Content,%<\/td><\/tr><tr><td>PVA&nbsp;2488\/BP24<\/td><td>10<\/td><td>12.5%<\/td><\/tr><tr><td>Deionized&nbsp;water<\/td><td>70<\/td><td>87.5%<\/td><\/tr><tr><td>Total<\/td><td>80<\/td><td>100%<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mix PVA and water in the mixer at temperature 50-80C till PVA granule all solved.<\/li>\n\n\n\n<li>PVA, better to choose middle molecular weight.
