Ok. I've been using the the cold process for homemade nitric and havd had different reactions each time I changed an ingredient. Meaning instated using drain cleaner for sulfuric and sodium nitrate at first. Which the sodium nitrate came from synthesis involving ammonia nitrate and sodium hydroxide. Then I changed over to battery acid for sulfuric. Which changed the reaction, then I changed the way I was drying my converted sodium nitrate and once again. I got a different reaction. Well now I've went to potassium nitrate
