I decided to share my tips with the world - or at least with those who read this blog. Over my 2 years in studio I have learnt some useful tricks maybe you know them already :)  1.  Talc is super useful (I was using pure talc the one you add to glazes but I think you can try it with baby talc as well) :  slipcasting - brush the inside of your mould with a thin layer of talc and your casts will relise easily each time :) But   it can also develop a shiny glaze like surface when fired on porcelain ( I didn't try it on other clay bodies) so plan before you use it and make sure the bottom part of your work in talc free as it can stack to the kiln shelf; 'glazing'- if you want nice shiny finish on porcelain brush a layer of talc on green body - clay has to be a bit wet so talk can stick to it. It's just a matter of practice to find out the perfect stage of clay and amount of talc you need. 2. Single firing  For over a year I was only single firing and nothing explod
