I'm with Melanie - and strive to find the older Effetre White to use on my Hot Head; it's what I use in all my murrini!
While making my Jesus Murrini, for example, I was terrified that my White would go "toasty marshmellow"
. But gentle heat through the 3.5 hour torching session to create it and using the "Effetre" White especially, made it a success!
See?
My humble recommendation...
