There were multiple pins (and I also googled it) on how to make these crayon creations and the temperatures in the instructions all varied. We have a gas oven and the lowest setting I read was 150 degrees all the way up to 300. I tried 230 based on the one website - well they were not melting. So I tried 250 and it took about 20+ min for it to melt at that temperature. (Most sites said 15-20 min). The first batch not all the crayons were melted and it still mixed on the top causing the yucky brown. DD1 wanted to mix up the colours so that's what we did. The second batch I tried to convince her to stick with more like colours but she still ended up doing some mixing. Both batches I had one botched crayon - one wasn't fully hardened when I tried to pop it out and the 2nd time around one (which turned out nice for colour) broke in 1/2.
