  1. Hello everyone, I am hopefully going to be embarking on a journey soon enough of selling some log cabins. I am hoping that I can figure out a way to make a mold of the design so that I will have an easier time producing them. Here is a LINK to some pictures of one. I am wondering if, with some modifications, a mold is able to be made of a complex shape such as this? The roof is separate and I would be making a separate mold for it. Are the amount of details added, such as the window panes and door frames too much detail for a mold master and would be better added afterward? The windows themselves would not be cut out yet of the mold master but is the hollow inside a problem? I am thinking since it is hollow than it would have to be a slip cast mold but since there are so many over hangs I am guessing it would not just slide out easily? Would a two piece slip cast mold work though - that is split horizontally? This way it just pops off? As for my slip cast mixing question. I've been doing some research and see that sometimes people say it has to be mixed for hours while other instructions only mix for 10-30 minutes maybe. Are hand drills with say a jiffy mixer used often and successfully in mixing slip or do industrial mixers need to be used? Thanks in advance for any advice and I hope this makes sense.
  2. From the album: Monoprinting with plaster

    Tile I made using a plaster slab, underglazes and porcelain casting slip, learned technique in Andrew Wandless' book 'Image Transfer on Clay' and also Joanne Veevers on CAD. This is still in greenware stage, not entirely sure how all of those colors will look as bisque and then glazed
  3. I have been given a 25kg bag of powdered porcelain. If I want to use this to make casting slip, what other ingredients would I need and in what proportion? Also, could I use it for throwing - if so, same question, what else would I need to add? I hate to waste a 'freebie' so would welcome any helpful comments.
  4. Hi, I'm mixing VC vitreous white /\6 casting slip, which calls for 3.5% Darvan 7. Unfortunately I cannot get Darvan 7 any longer and was sold Darvan 811. I'm trying to find out how much DArvan 811 to use as it is "much stronger"....very vague. Research on the internet, and phone conversations with reps from the manufacturer (Vanderbilt) and Laguna haven't helped much as they say "to add little by little", "don't use too much", "wait at least 24 hours after adding Darvan 811, as it works much slower than Darvan 7". I have done all that but the slip still feels thick and almost gooey. I don't know how much Darvan is too much. Does anybody have had this experience, and found a solution? Vitreous white /\6 grolleg 25 EPK 25 Kona F-4 30 frit 3124 4 flint 16 bentonite 2 H2O 40-50% darvan 7 3.5 grs darvan 811 ????? Thanks, raymonde
