I was expecting a little more but I also thought I had 2 more #'s of chips than I actually had. So my yield was really spot on for the actual amount I had. This button has been picked up already and another roughly 12#'s of ceramics dropped off.

Hi Tyler- can you clarify what 8# means please? I'm trying to work out what your average yield per chip is and I'm obviously a little confused- because heck I'd love to get that yield from 8 !!!

Cheers

Jon
 
Thanks Dave and thanks Tyler.

What was the average proc count per pound please?
 
Honestly Jon I couldn't even tell you. It was a pretty random batch with 3/4 of the weight coming from the low yield pentiums/K6's. How about this Jon I got another 12# from my client last night and I will try to keep a chip count this time in comparison per #.

Tyler
 
Thanks Rob for the offer I might have to take you up on it soon. Jon I have weighed and counted this batch of cpus and there is a little over 12# and 202 cpus. So this batch is also a little over 4# heavier than the last.

Hot spots can be created with powders or solids sitting on the bottom of a heated vessel, these can sometimes cause the vessel to crack or break, I do not know how hard you are heating that vessel, but in any case using a corning dish between your hot plate and the vessel, can help catch your values if something does go south.
 
Thanks for the advice Butcher as I usually do have corning ware under my beakers. This thing is super thick and so big I don't have a dish big enough to put under it. It's a 12,000 ml beaker and I just have it on between low and warm heat setting. I don't heat my solutions hot ever just a little heat to speed it up a bit. I can grab it by the bottom with my hands.

Well here it is from the second batch 18.85 grams! It got scratched trying to pull it out of the dish. Spaceships-120 cpus still have 3.5#-79 cpus of K6's to run.

Haha Tyler, as Kuuby says you're doing really well. I'm beginning to get jealous because I've got nowhere to refine my gear for a short while and I'm having to get someone to do it for me!

Looks really good. There's no "here's 3g and be grateful for it" goin' on here that's for sure. 8)
 
one thing i have learned on my own and confirmed here on the forum, the thicker your vessel is, the more susceptible it is to thermal expansion. i would still use a catch pan just to be safe.

Correct. Pyrex made it perfectly clear that the heavy wall cylinders they sold were not to be heated. Their heavy duty Griffin beakers, for example, had a heavier rim, but the balance of the beaker was not thicker, otherwise they were more susceptible to thermal failure.

I have to admit---I never used a catch pan when refining. However, my setup was such that if I experienced a broken vessel (very rare), I could recover virtually 100% of the lost solution, so long as it wasn't a large volume. It would all be contained within my fume hood.

While I commented that it was very rare to experience a broken vessel, by that I mean one that has become more than one piece. Cracked beakers were relatively common, as they got badly abraded inside, due to processing polishing wastes. As they degraded, they'd eventually crack around the bottom, but rarely came apart. I kept watch and discarded a beaker the moment it showed a crack.
