挺恶心的,农村老屋墙沿都有这种白色结晶,都是日积月累的老尿苔

其实不是尿苔,是以前的劣质水泥析出的一些硫酸盐硝酸盐

好吧,长知识了

尿苔不就是硝酸盐

黑火药还缺一点硫磺,想起小时候真的去农村刮硝酸钾然后药店买硫磺自制黑火药,最后结果当然是无法爆炸,只能烧着玩

是不是没加白糖

原来硝酸钾这么容易弄到?墙根就有?

老一辈的农村人很多都知道

我没记错的话还有很多老人会直接炖肉时放一些,说是加了能炖的更烂

上面不是有人说是老尿苔么,怎么到你这儿又炖肉了?你俩谁说的是真的呀?

[-] Ill_Paleontologist19 | 1 points | Apr 03 2021 16:13:37

对啊,老人说这种硝放肉汤里头炖的能更烂,想想就很恶心

什么自产自销大众汤料
