kenk Posted July 28, 2015 Report Share Posted July 28, 2015 I'm interested to use some use sodium silicate to create the crackle effect on my pot. I understand that you apply the sodium silicate to the bowl , then continue shaping it by pulling out the wall from the inside. My question is , do you need to add slip to the pot before adding the sodium silicate . Or is that optional? Any other suggestions or guidance would be helpful. Thanks, Ken Link to comment Share on other sites More sharing options...
PRankin Posted July 28, 2015 Report Share Posted July 28, 2015 I apply the sodium silicate directly to the clay after throwing. I let it dry in the sun for at least two hours before stretching it. I have also mixed the sodium silicate in colored slip and applied that to the cylinder to get a more contrasting effect so it's up to you how you would like to proceed. There have been a few previous discussions on these forums about how to dry the outside of the vessel and you can search the forums for that info. Some use a blow torch or hair dryer but I prefer just leaving it outside while I throw some others. Good luck. Paul Link to comment Share on other sites More sharing options...
Marcia Selsor Posted July 28, 2015 Report Share Posted July 28, 2015 You can apply a slip before the sodium silicate as Randy Brodnax demonstrates on a CAD video. This gives a good contrasting color. I apply sodium silicate and dry it with a blow torch or heat gun. I have air dried it indoors. Where I live has a constant sea breeze and would dry unevenly if I put it outdoors.
