back with some different slime recipes. Pictures for this round of tests are in this album: https://umd.net/profile/i/indigoodragon/section/photos/album/march-22-3

Materials

Two types of HEC: Natrosol HHR 250 and MessySupplies Untreated HEC.
K Lube was added to the majority of these slimes to get a bit of stretch

Mixing
Natrosol and Untreated HEC mix very differently. Natrosol needs to be mixed for at least 5 minutes in hot water until it starts to set, and then needs about an hour to fully saturate. Untreated HEC reacts much faster, and only needs a few minutes of mixing in warm water in order to set. Everything was mixed with a paint mixing attachment on a drill, paint added first.

When adding K Lube to Natrosol, you can do it any time before it starts to thicken. When adding it to Untreated HEC, you'll need to combine the powders and mix at the start.

Coloring was once again acrylic paint from Dick Blick. Tempera paint works too if you're concerned about staining.

All recipes use 10L water as the base. With that out of the way, here are the recipes tested:

- 150g Natrosol HHR 250 / 8g K Lube. Nice and thick, bit hard to see the stretch from adding K Lube.

- 170g Natrosol HHR 250 / 8g K Lube. Really liked this one. Since it's so thick, might have to add more K Lube to get that stretch effect I like.

- 115g Natrosol HHR 250 / ~2g K Lube. This one was a bit of a mishap as I forgot to add the K Lube until it was too late. Still nice, but a bit thin for me. Looks like you get a larger stretch effect with less Natrosol added relative to the K Lube.

- 115g Untreated HEC / 8g K Lube. Stretchy but too thin for me. You might like it though! Photo ref: https://umd.net/showpic/image/media%2Fphotos%2F4_22%2Fvlcsnap2022032618h26m54s428_uid_102825_1650326771_56748.jpg/return/%2Fprofile%2Fi%2Findigoodragon%2Fsection%2Fphotos%2Falbum%2Fmarch-22-3

- 140g Untreated HEC / 8g K Lube. My favorite of this batch, thick, heavy, and stretchy. You could maybe bump the HEC up to 150 but it might get hard above that, as it sets extremely quick.

What about Tylose?
You might remember that last time I did this I used Tylose HS 60000, and it really does mix different. I prefer it over both Natrosol and the Untreated HEC, but the Untreated HEC mixes very similarly.

If you are using Tylose HS 100000, the recipes I posted previously will work but with the amount of Tylose multiplied by 2/3 (the HS 100000 is a higher molecular weight). I've found that I like 120-140g of the HS 100000 + 6-8g of K Lube (it's fantastic).
