Back with the release of R23 (October 7, 2015) several of the recipies for core items were changed, including power cells. This prompted some discussion, particularly among those who had been familiar with the original recipes, during which the subject of durability came up. I did a simple test in R23 on durability. Original post is in this thread: http://steamproxy.net/app/280790/discussions/0/481115363859975526/

Then R24 (October 28, 2015) was rolled out, which changed the durability. I ran a bit more thourough set of tests.

On June 16, 2016, R32 gave every mining cell (or lack thereof) the ability to pullup any crafted block. I didn't think about updating this guide at that time, so this info is being added with the R39 update info.

On February 22, 2017, R39 removed the wood cell and the charged wood cell recipes from the game, and made the stone mining cell the first crafted mining cell. While I have moved that data out of the progression and altered the tier ratings of the remaining cells, this may require a reevaluation of the stone cell, at the very least.

The "The Data" section has the findings from the R24 experiments.
The "Block Tiers" section (currently a work in progress) will give some (perhaps eventually all) block examples for each tier.
The "Data Contributors" section will list who else has contributed or verified information here. This will also serve as a list of who to blame if I find incorrect info :)
The "TL;DR Stuff" section will detail how I went about the tests as well as anything else I feel like adding that isn't specifically pertaining to mining cell durability :)

With that said, onward to The Data.

Updates:
February 9, 2016 - Added mining cell recipes to The Data section.
February 26, 2017 - Added some info about block pulling changes made in R32, released on June 16, 2016 and did some data rearrangement based on recipe changes made in R39, which was released on February 22, 2017.

Legacy Data
In R39, released on February 22, 2017, the abililty to craft wood cells and charged wood cells was removed from the game. The reasoning being the wood cells only were able to harvest one more item than having no cell, and it confused some players having that in there. Existing in game items were not deleted, but no further items could be crafted, and no further recipes drops (in the case of the charged wood cell) would occur.

• T1 - wood cell (4 any wood, 1 red mushroom, 1 vines)
  
  • 280 on T1 blocks
    
  • 560 on T0 blocks
  
  
• T1 - charged wood cell (chest loot drop recipe; same recipe as normal wood cell)
  
  • 300 on T1 blocks
    
  • 600 on T0 blocks

As a general rule, this is about what you can expect for block tiers:

• T0 blocks, no cell required - I think everything found on the surface (tree parts, flowers, vines, grasses, bushes, 'shrooms, beeswax, etc.) as well as most surface found ground blocks (grass, savannah grass, detritus, dirt, rocky dirt, etc.) including sandstone and canyon floor, but not any other canyon block or fluids
  
• T1 blocks, wood cell required - stone
  
• T2 blocks, stone cell required - bedrock/limestone layer, peakstone, canyon stones
  
• T3 blocks, obsidian cell required - siltstone/stalactite level
  
• T4 blocks, iron cell required - lava layer
  
• T5 blocks, diamond cell required - corruption
  
• T6 blocks, lumite cell required - lava, corrupted water

For some specifics (I'll try and work on fleshing this out with anything and everything I can lay my mining cell on), here's what I have so far:

• T0 - No cell required
  
  • molasses, trees (trunks, leaves, flowers), tall grass, vines, red mushroom, brown mushroom, glass, sand, turnip, lettuce, wheat, horned melon, dirt, grass, coral, beeswax, wood stairs, wood wall, wood roof, wood fence, wood window, tundra flower, wildflower, thatched wall, thatched roof, red wood wall, moss
• T1 - wood cell
  
  • stone, coal torch, stone path, natural stone path, stacked stone wall, stone chest, mud
• T2 - stone cell
  
  • limestone, bedrock, gas lamp
• T3 - obsidian cell
  
  • banded golden wall, studded golden wall, golden wall
    water, stalactite, siltstone
• T4 - iron cell
  
  • tar, hardened lava, igneous rock
• T5 - diamond cell
  
  • bog water, mineral water, corrupted wood, corrupted grass, corrupted dirt, corrupted stone
• T6 - lumite cell
  
  • lava, corrupted water

• fatmacman verified the undertier harvest quantity for lumite mining cells in the orginal thread.
  
• J's contributed the durability information for charged wood mining cells in the comments on this guide.

For reference, most of this guide is copy-pasted out of this thread
http://steamproxy.net/app/280790/discussions/3/490124466458641971/
and pretty much all of this section is just a more verbose version of "The Data" above.

Originally, I did a simple test in R23 on durability. Original post is in this thread:

Първоначално публикувано от AvilerED on R23:

Okay, so here's what I've found. I harvested only "at tier" blocks for all cells up through diamond. I haven't gotten to a point where I have all the resources for lumite on the world I tested on.

"At tier" blocks are the first blocks that a particular cell is rquired to be able to mine them. So, stone is the at tier block I used for wood cell, bedrock (and 3 limestone) is the at tier block I mined for stone cell, obsidian used on siltstone, iron used on igneous, and diamond on corrupted stone. Here's what I found:
140 at tier blocks with wood cell
200 at tier blocks with stone cell
250 at tier blocks with obsidian cell
300 at tier blocks with iron cell
400 at tier blocks with diamond cell
Lumite should theoretically harvest more corrupted blocks than diamond because it is 1 tier up from the minimum cell required to harvest corrupted.

With R24 having some durability changes, I thought I'd try it again.
280 stone blocks with a wood cell
300 limestone blocks with a stone cell
350 stalactite and siltstone with an obsidian cell
350 hardened lava and igneous rock with an iron cell
400 corrupted blocks (dirt, stone) with a diamond cell
600 lava blocks with a lumite cell

Edit November 29, 2015: I did finaly notice that lava blocks require a lumite cell, so I went ahead and burned through one on lava blocks in R25.

Wood cell durability appears to be doubled, 100 block durability increase for stone and obsidian cells, 50 block durability increase for iron cells, and no increase for diamond cells. With no increase in diamond cell durability, I'm also guessing that lumite did not get an increase. Not having tested before R24, I couldn't say for sure. I think I want to test out a few more things regarding durability, as well. I'll keep y'all posted on what I find.

Edit #1: Let's discuss tiers (T#), now.

T0 blocks are stuff you don't need a cell to harvest, T1 needs the T1 cell (wood), T2 needs T2 (stone), T3 needs T3 (obsidian), T4 needs T4 (iron), T5 needs T5 (diamond), T6 needs T6 (lumite). Block examples, from T0 to T6; dirt, stone, bedrock, siltstone, igneous rock, currupted stone, lava.

Wood cell (T1) will always lose durability on whatever it can harvest
Stone cell (T2) can harvest T0 blocks with no durability loss
Obsidian cell (T3) can harvest T0 blocks with no durability loss
Iron cell (T4) can harvest T1 blocks with no durability loss
Diamond cell (T5) can harvest T2 blocks with no durability loss
Lumite cell (T6) can harvest T3 blocks with no durability loss

This may help you in planning how to maximize your mining cell life.

Edit #2:

After some further testing, it appears that when harvesting lower tier blocks, you can harvest twice as many blocks as you can "at tier". I tested wood, stone, and obsidian fully, and iron at T -2 and for all instances both T -1 and T -2 were twice what the at tier quantity was. So, hypothesizing that T -1 for iron and both T -1 and T -2 for diamond and lumite will follow the same pattern:
Wood cells are 280 at tier, 560 lower tier (verified)
Stone cells are 300 at tier, 600 lower tier (verified), infinite on T0
Obsidian cells are 350 at tier, 700 lower tier (verified), infinite on T0
Iron cells are 350 at tier, 700 lower tier (T -2 verified, T -1 hypothesized), infinite on T1 or lower
Diamond cells are 400 at tier, 800 lower tier (hypothesized), infinite on T2 or lower
Lumite cells are 600 at tier, and are 1200 lower tier (T -2 verified (thanks fatmacman), T -1 hypothesized), infinite on T3 or lower

I think that's about all the testing I'm going to do on this, I've satisfied my curiosity. If anybody wants to verify iron cells on T -1 blocks (siltstone/stalactite), diamond cells on T -2 (siltstone/stalactite) or T -1 (lava layer), or lumite on T -1 (corruption), feel free.
