I am trying to find a recipe for cone 10 Porcelain slip so I can dip fiber art in them for firing. I came across one from a classmate but she made one so long ago. I had a hard time understanding her explaining the recipe. I copied her recipe and now asking you guys if anyone with experience would tell me if this recipe is correct or not. I wrote down exactly what I saw on her paper but I don't understand some parts of it. I am very new at mixing glazes and slips. Forgive me for any spelling errors. Corrections are appreciated!

Mix first:
Barium Carbonate 1/2 oz
Soda Ash 1 oz
Water 5 gallons
Sodium Silicate 2.5 fl oz

Dilute 50/50 with water

25% Super Standard
25% Grolleg
2% OM4 Ball Clay
28% Minspar or G200
20% Silica

Gumplast 1 pint
Darvan 1 tsp - small like eye dropper

Makes 100 lbs slip

I hope you understand I do not want to ruin the kiln or accidentally destroy other people's work in the kiln should this slip fail and make a mess. :/ Thanks in advance for your feedback!
