I purchased Rise and Shine mica looking for a nice pastel yellow.
I have used this mica twice now. Both times it heated up my batter and accelerated trace. I had to abandon my swirls and spoon the batter into the mold. I have been making milk soap from many years now, so I am experienced. I used frozen milk cubes and soaped at around 80 degrees. I brought the batter to emulsion and added it to the mica mixed with a small amount of oil. Both times it turned Shocking Neon Orange and got quite thick. It stays shocking Orange for several days. Once it turned to yellow, it was a very bright yellow, rather than the pastel that I was expecting from the colour of the packet. I wanted the soap to look like a baby chick. People think it is a rubber duckie!
I do NOT recommend "Rise and Shine" mica.
I will stick to using "Love and Sunshine" Yellow Mica is it is my favourite and always works perfectly.
