Radioactive glazes[edit]

Brilliant red Fiesta (and indeed the red glazes produced by all U.S. potteries of the era) is known for having a detectable amount of uranium oxide in its glaze, which produced the orange-red color. During World War II, the government took control of uranium for development of the atom bomb, and confiscated the company's stocks.[6] Homer Laughlin discontinued Fiesta red in 1944. The company reintroduced Fiesta red in 1959 using depleted uranium (rather than the original natural uranium), after the Atomic Energy Commission relaxed its restrictions on uranium oxide.

Red is not the only color of vintage ceramic glaze that is radioactive; it is detectable from other colors, including ivory.[7] The level of radioactivity of vintage fiestaware has been published and is available online.[7][8]

The U.S. Environmental Protection Agency warns consumers not to use radioactive glazed ceramics for food or drink use.[9] Others recommend against using such pieces for food storage due to the possibility of leaching of uranium or other heavy metals (often present in some colored glazes) into food, especially acidic foods.[citation needed]

On March 16, 2011, the Homer Laughlin Company posted this statement on its website, in response to a Good Morning America broadcast about radioactivity in the home:[10]

Included in the report was a product that has not been sold in the market for nearly 40 years, Antique/Vintage Fiesta dinnerware. The anchor narrating the segment passes a radiation measuring tool over several products including the Antique/Vintage Fiesta plate that was produced nearly 70 years ago. The narrator also stated that it was taken off the market because when people heard about the uranium in the glaze, they did not want to buy the product. In fact, The Homer Laughlin China Company stopped manufacturing all Fiestaware in 1972 because of low sales. The product that was used within the segment has been discontinued and has not available for close to 40 years time. Fiesta today is frequently tested by federally licensed independent laboratories and is lead free, microwave/dishwasher safe, oven proof and made in the USA. . . .

Prior to World War II, it was common practice for manufacturers of ceramic dinnerware to use uranium oxide in color glazes. The Homer Laughlin China Company was no exception, using this material in the original “Fiesta Red” glaze, among others.

In 1943, the U.S. Government stopped all civilian use of uranium oxide because available supplies were needed for the war effort. Homer Laughlin stopped producing the red glaze color at that time and for that reason. Nonetheless, this interruption in production is believed to be the source of the rumor that Fiesta’s red glaze was removed from the market because it was radioactive. In truth, the red glaze emitted far less radiation than some other consumer products. Following the lifting of wartime restrictions, Homer Laughlin again began producing the red glaze in the 1950s, using a depleted grade of uranium oxide.

Homer Laughlin stopped all use of depleted uranium oxide in 1972 and it is not used in Fiesta Dinnerware which is produced today.

用的不是餐具，是惨剧

铀盐是硫酸铀么。。。

楼主的动手能力很不错，做的很漂亮。（如果做能成一块窗户就更好看了。）

越危险的东西越美丽……

正式的做釉是用氧化铀，但实际上什么盐都行，只要有那个离子

这个公司可以用铀做出红色的釉，很少见啊。不过把铀掺在釉里面很早就有了，凡士林玻璃也有做成杯子之类的东西，到底有没有人用就不知道了[s::lol]

妈的 铀盐去哪里搞？

用钙铀云母强酸溶解，过滤蒸发应该可以

直接加云母也行，不管怎样熔融液体里都会有点渣渣，要静置除去

准备淘宝一些熔接用的玻璃粉，我看那些玻璃材料温度非常低，有的甚至200多度软化400度液化，不知道实际效果如何

表示用电阻炉熔的烧杯没有出现绿色

感觉可以拿这个来当放射源做闪烁镜玩。楼主去试试看吧。我一直都准备买块铀玻璃成品或者钍矿来搞个闪烁镜，这下看来可以自制了。

屏比源贵系列.....

1200度熔化玻璃应该没什么问题，我在家用酒精喷灯烧过玻璃管，烧久了表面可以轻松熔化的，可以把玻璃棒表面加热融化后粘一些铀盐再烧，表层有铀应该就可以达到效果了吧。如果用软料的话更容易化。

烧软是不够的，需要离子进入玻璃，起码要很稀的液态。手头只有实验室用的高硼玻璃，可是相当难熔啊

• 烧软后应该是可以扩散的，时间久些一两毫米大概可以。我之前烧的也算是硬的玻璃，本来是想把铜丝封在玻璃里头，没成功，但是玻璃那一小片变红了，我觉得可能是亚铜离子渗进去了吧，当然只是猜测。
• 玻璃难熔我觉得可能还是温度和功率差一些吧，当然厚度与材质也有关。我先前买了硬料，用天然气灶头烧，纹丝不动，又去玻璃厂指明买软料，结果只是变软。后来一狠心买了酒精喷灯，点着了相当吓人，呼呼呼的，硬料上去十几秒就发红软了。
• 家里要用坩埚类器皿熔融玻璃是很难的，一来要求温度高、散热偏偏又剧烈，二来容易裂、炸，三又不好取出，工业上是用专门的耐火砖砌池子熔玻璃，规模太大。我建议你找找手工做玻璃珠的视频，把玻璃棒熔了慢慢涂在金属丝上，边烧边涂，有点做糖葫芦的感觉，如果一层一层涂的过程中顺便粘一些处理过的铀料，大概可以做出铀玻璃珠（还带孔）。

早试过了，效果不理想，所以用了硼砂
