  1. @Minim sure I have replied .... but don’t seem to see .... Thank you for your invput ...... I have not fired the test tiles as of yet .... As I wanted to resolve the issues that I have:Ie underglazes very thin and stain rather thick But thank you Think I’ll just stick to different clays and forget about colors ( learning issue a bit of a problem :)
  2. @oldlady.... Thank you for your input .... not quiet sure where to see your test samples (?)
  3. @MinHi Min ...... Yes mixed stain powder and underglaze powder with 60% slip (and 10% stain or underglaze ) Slip is same body as the pots are made from.Αll premixed from same body
  4. HELP ..... ... Trying to get back to ceramics .I’ve just finished mixing a small quantity batch of stains and underglazes with slip ( same clay bodies nothing else ) I’ve used 60 % slip to the ratio of about 10% stain to both stain and underglazes But have found that the underglaze slips are much thinner than the stain slips .Consistencies are different .Most stains seems to be thicker than underglazes Aside from black and purple which are def thinner . How to rectify ......???? Do I add more slip or stain to thicken ??? Or is it more complicated than I imagine . ? Bare in mind I am not adding anything else ie frits etc Thank you Nicky
  5. @MinHi Min ........ Did not dilute underglaze (good shaking ) Waited as each coat dried . Found that two coats doesn’t give me the opaqueness I’m looking for . Don’t use cones
  6. @Roberta I only use blacks on these .I’ve tried using stains ( on greenware ) .But was not happy with the results either
  7. About cone 6 ( from what I understand ) . But why would some work and others not ? Could this then mean different heat on top bottom shelves ?
  8. Hi Must be beginners luck ....... Second unsuccessful firing .These are thin porcelaine slabs .That I coated with three layers of underglaze. And fired to 1240 degs .Some came out okay and others had these blister effects Any thoughts would be appreciated Thank you Nicky
  9. @Bill KielbYes will definitely do next time . Thank you
  10. @Bill KielbThank you .........Had a feeling might have been too thick .And make a note of clear glazes need to be thinner . Guess I’m learning the hard way .So yes think I will have to learn to do “test tiles”
  11. Hi ...... Did a glaze firing using black and white porcelain , using the same transparent glaze On the white it sat very well On the black came out milky with spots ( tho was told this glaze works well on black porcelain as doesn’t give a brown color after firing ) The other issue I had with the black porcelain is that the glaze stayed quiet wet after dipping ,and did not adhere on rims well Thank you Nicky
  12. @liambesaw Think I have to give that a miss .... Way to advanced for me .Tho did look it up Thank you . Nicky
  13. @Min Thank you Min .......... Appreciate your input and help .Will keep on trying .
  14. @liambesaw Would just like to make sure that I understood well .Porcelain slip can be used on bisque fired stoneware . But not on greenware or leatherhard stoneware clay Thank you Nicky
  15. Hi ......I remember reading somewhere that one can use a clay body and then use “ porcelain slip “ over it . Is this feasible ? I use a stoneware that fires to bisque 980 and glaze goes to 1020 degs . I fire my Audrey Blackman porcelain to 950 bisque and glaze goes to 1240 degs . My question is could I use “ porcelain slip “ on my stoneware ? And is there something extra I should be adding too the porcelaine slip ? Thank you Nicky
  16. @Bill KielbHi Bill thank you so much for your “expansive “ and detailed input ..... Really appreciate . Tho clear I hope I understand ( have a slight learning disability )But at least now have something to refer too . Kind regards Nicky
  17. If someone could please help me by simplifying the differences for me between “ slip , engobes and underglazes “ I use both porcelain and stoneware . And fire in an electric kiln 1) Slip is used mixing same clay body with stain and water . And applied to leatherhard only . (what other are ingredients could be used in stains for different surface effects ?) 2) Engobes are used only on leatherhard (?) 3)Underglazes can be used both on leatherhard and bisque (?) . Thank you so much Nicky
  18. @PeterH Min came up with the idea of tongue test ....... Therefore you input was right as too “one fired “is vitrified Use Audrey Blackman porcelain Thank you for your input :-)
  19. @Mark C. Mark thank you so much for your time and input Just tried the tongue touch and seemed to work :-) But will bare in mind your advice too :-)
  20. @Min ....... Thank you Just did the tongue test Worked perfectly :-)
  21. @Mark C. Yes one high fire with porcelain clay (sorry don’t remember exact temp prob 1240degs I didn’t want to glaze that particular batch .When firing porcelain bisque I fire up too 940 degs and glaze to 1240 degs I don’t use cones
  22. Hi ....... Fired two batches of porcelain ware .The one was “ onefire “ And the other “bisque» My problem is they got mixed together. Now I cannot tell the difference as I want to glaze the bisque ware .Is there a way of testing the difference Thank you Nicky
  23. Thank @Min Greatly appreciate your info and input Have nothing to loose as I don’t want them plain So will try underglaze and engobes And see what happens Nicky :-)
