so i plan to do an STB tek with some salt added into the mix
i plan to be using a karter boro glass 1l media bottle to make my soup and do my pulls from, i have a seperate 500ml boro media bottle i plan to mix my lye/salt water solution in after it has cooled to room temperature and then mix over the next 24 hours before adding solvent. I plan to water wash and have a 100ml boro graduated cylinder i plan to do for this. I also bought PTFE sheeting so i could place under the cap of the media bottle's.
the procedure i have planned in a nutshell is as follows:
100g of bark with about 650ml distilled water in a 1l media bottle, then mix 250ml distilled water with about 30g lye and 10g non ionized salt making sure to pour the lye slowly into the water, in a 500ml media bottle. Let the lye solution cool down for a couple hours to room temp then add to MHRB water, and mix well let that sit for 24 hours then add 75-100ml NPS (see nps question below still a little confused on how 75-100ml will compare in the width of the media bottle vs the 1l flasks). Mix that up 4-5 times throughout the day then once it's seperated after the last mix, do your first pull, water wash it, freeze percip 18-24 hours pour off excess NPS back into soup jug and repeat for 2ish more pulls
list of materials as follows and recipe for now:
equipment:
10ml glass pipette (boro)
1l media bottle (boro)
500ml media bottle (boro)
100ml grad cynlinder (boro)
100ml 4x4" glass funnel (boro)
glass stir rods 16" 12" and 9" (boro)
planned recipe:
900ml distilled water (initially going to be divided into 2 containers at the start 650ml/250ml
100g of powdered MHRB
30g lye
10g salt
100ml naptha (or would 75ml still be fine in the width of the media bottle over the erlenmyere? just wondering you probably dont want too thin of a layer of naptha to pull from but obviously dont want too much naptha, any insight on how many ml of naptha to use for 1l media bottle would be great as i have not been able to do this yet, everything should be arriving by next week)
one of the main questions i still have has to do with the initial exothermic reaction of the basic solution in the 500ml media bottle, i am assuming you dont want to cover the lye water mix when it is cooling down? just leave that one open to vent because there is an exothermic reaction taking place and that could cause pressure to build?
when adding the solution to your main soup jug, do you also leave this open to vent while it is sitting for the next 24 hours? do you leave the lid on loosely? is it screwed on tight? is it just the exothermic reaction in the initial mix of the basic solution that is the only concern?
thank you all for listening to my questions! hope you are all having a wonderful day
Edit: nevermind! Looked a little more through the forums and found the answers I was looking for. My apologies for being a bit impatient. I could've easily answered my own basic questions and did with a couple more searches and going through the faq.
