Try a wee bit hotter with the wax try pouring in and out at least twice may be three slushes you can also give the alginate mould a brief blast of hot air from a hair dryer
and also get the wax in as quick as you can on the first slush
I use plastelina witha 50 to 55 sure hardness here in England
Water can be a problem in the finger tips chilling the wax on contact good luck
one question why are you using wax is this the final material for your cast is it for lost wax?

Question re: pink house:--
Folks, I'm very new to this and have a question I hope isn't too basic. I'm using Pink House slow-set for hand molds. Into the mold I'll pour freeman flakes pink injection wax.
6 times out of 10, the wax positive will come out with a "water bubble" defect. Typically this is on the pads at the finger tips and it clearly is a "water bubble" between the alginate and wax, not air.
I'm mixing the alginate on the thick side and according to Pink House recommendations. I am also being careful to keep the wax not too hot, not too cold. By too hot I mean "bubbling" and by too cold I mean "flow lines in the model".
Have any of you encountered and solved this issue?
