Math Help Needed For Recipe

27 March 2015 - 05:39 PM

i have a recipe for a white matt glaze that comes from Charles Counts via his apprentice, Susan Maslowski.  i was given the recipe in the 1970s and the paper is so yellowed it looks a hundred years old.  this was his standard exterior glaze and the batch size was large, i usually make it in a 5 gallon bucket.  i need to give 100 grams to a friend to try on her clay body.  the big bucket is 1000 miles north of here.

 

could one of you math majors please help me reduce the size correctly?

 

 

translucent white matt glaze  cone 6

 

nepheline syenite                     1161

silica                                           126

whiting                                        423

zinc oxide                                   193.5

e p kaolin                                    346.5 

 

i know it doesn't add up to a neat number, but it works very well over colored slips.  thanks for your help.


Today Is The Gasparilla Craft Show, Outdoors In Tampa

and i cannot hear myself think because of the pounding rain smashing onto my roof.  the forecast was for a 40% chance of rain.  if this is 40%, there cannot be any rain left for anywhere else.

 

oh, those poor exhibitors.  some come from a thousand or more miles away.

Sycamore Pottery Is Selling Red Copper Oxide, Anyone Have Info

26 January 2015 - 02:32 PM

i have never heard of this and wondered whether it is a good thing to have.  digitalfire says something a chemist could understand but i cannot.  is it worth buying if i only want to use it in my green ^6 glaze which is done with copper carbonate?  only reason i care is that it is close and cheap.
