In the past couple of weeks I was looking at form. Whole time I was going back and forth from rectangular to round form. At the end I have decided to give another try with round form this time perfectly round. As a result I have achieved shape I am relatively happy. Also, using pure paraffin, without any hardener made the form look crisper and clearer. Of course, more experimentation with form is necessary, but I feel I am on the right track. Next step will be securing my mold so it is each time right in the center, working out my release (canola oil) and making sure that outcome looks nice, clean and crisp.
