I'm back again with more novice questions 
As always, I'm appreciative of any responses~!!!!
I am intrigued about the prospect of prewashing my ra4 paper but I have some questions.
I have read this: https://emulsive.org/articles/my-ra...hooting-and-processing-colour-paper-negatives
1) can the runoff from the washed paper go down the drain? or would that also have to be disposed of properly (i.e. in a facility)?
2) The site above mentions ISO of washed paper being 12. Can anyone confirm this? It would be wonderful to have a second source backing this.
3) It mentions that without the coating the temperature of the paper is 3200K. If my lighting conditions were also 3200K, would this mean that wouldn't need any filters?
4) is the paper more toxic without the coating? Should one handle the paper any differently following prewashing?
Thank you in advance for your guidance and mentorship, photorio respondents. It means the world!
