03 Sep 06 - 04:07 PM (#1826126) Subject: BS: Math Calculation From: John Hardly I have the following glaze already dry mixed. I don't need it anymore. EPK 2500g Feldspar 5270g Whiting 2130g Talc 400 Red Iron 600 Bone Ash 400 I do need the following glaze which contains all the same chemicals but in different amounts (plus one extra chemical) EPK 2500g Feldspar 5270g Whiting 2130g Talc 400g Red Iron 400g Bone Ash 300g Rutile 400g What would I have to add to the first (already mixed) batch to convert it into a batch of the second? |

03 Sep 06 - 04:39 PM (#1826141) Subject: RE: BS: Math Calculation From: Bee-dubya-ell Add the following: EPK 1250g Feldspar 2635g Whiting 1065g Talc 200g Red Iron 0g Bone Ash 50g Rutile 600g Or, just dip the stuff in the original recipe and spray a rutile wash over it. |

03 Sep 06 - 07:11 PM (#1826222) Subject: RE: BS: Math Calculation From: Dave the Gnome John, you realy need to get a set formula for this. You asked a very similar question four years ago. Mean to tell me you can't remember that far back? Probably working with too many chemicals... :D |

03 Sep 06 - 07:41 PM (#1826245) Subject: RE: BS: Math Calculation From: John Hardly It's so much more fun to take advantage of this folk-math forum. Actually, it's just the same case as the last one -- just a safeguard since I work alone -- someone to double-check my math. The upside is saving $50 worth of chemicals, the downside would be lotsa bad pots if I got it wrong. |

04 Sep 06 - 03:42 PM (#1826794) Subject: RE: BS: Math Calculation From: Bert Hi, you say ...I have the following glaze already dry mixed. I don't need it anymore... The quantities that you must add would depend on whether you used any of the original batch. If so, you must weigh it first before you do your sums. |

It was in one of my favorite childhood folktales. You get a little magic doll (left to you by your dead mother), you give it a little beer and bread, and it summons a horde of ants and commands them to remove the proper number of tiny grains. Easy. |
