Hello, I'm about to test some container. I don't have a lot of experience with containers, I only made some very large and I found out cd 18 was the choice. The wax I'm going to use is a palm wax for containers that looks like soy, it's in flakes and it behaves likes soy (don't know what wax is it, it's from pitisumi haiash and it's the only I have here in italy). The containers I found are glass tumbler, I chose these because they are inexpensive. The smallest has a 2.55 inch diameter, the largest is 2.95 inch. I have a lot of wick samples of different types, I have RRD, CD, HTP, WU paper core, ECO, LX.. I was reading the charst on wickit and wicksunlimited. They bot say all the wicks work well in natural waxes, I got a bit confused on wichs size to pick. Any suggestions on sizes to star with? The tumbler are straight, same diameter from top to bottom. From what I was reading here I got the idea ECO wicks have a lot of problem. Many thanks!
