Cons This torch has a reducing flame, so you will never get the full color effect of glass requires an oxygen-rich flame to strike (like some borosilicate colors)
Other Thoughts Overall, I would consider this to be a great (possibly the best) 'amateur' level torch. Great for the casual lampworker, but a pro lampworker will probably want to consider an oxy/acetylene torch instead.
Pros I tried this mold originally with Primo Primer, and the cast pieces did not fuse properly (they had little spikes at the top where the frit settled). After consulting Delphi, I switched to using MR-97 and the pieces turned out beautifully smooth and popped out of the mold easily. I would certainly recommend using MR-97 as the release for this mold even though it costs a good deal more than Primo Primer. The hole in the mold is the perfect size to hang the cast pieces, and cords and thin chain easily fit through it.
Cons The cast pieces are not particularly heart-shaped (the indent at the top of the hearts is not pronounced enough), which is a disappointment. Also, the "earring" sized cast pieces far too heavy to be worn as earrings, and I personally found the pendant sized cast piece a bit large to wear on a necklace as well (I would certainly call it statement jewelry). Having said that, the earrings made nice pendants and the pendant made a nice ornament to hang in a window.
Other Thoughts If you are considering using a mold which will make holes, I recommend Delphi's Simple Round Beads Mold instead- it casts 6 pieces instead of 3, and I consider all of the pieces it casts to be wearable sizes for pendants.
