Newspaper with plaster?

So I'm thinking of adding paper to plaster so i can mold it using my hands & when it dries it would become hard. Would it work?

(It's MeowingInsanely btw, i furgot my password XD)

edit: i can't find the "choose category" on my mobile =/ so it went to latex...

MEOW. yes you could get your paws into it and it will definitely go stiff then hard. if you drop plaster into a pale of water. it will set at the bottom of the pale.

As Michael said, plaster will harden at the bottom of the pail - even completely submerged under water.

Plaster is like cement in that once the hydration process starts, there's no stopping it. You can, however, slow it down. There are chemical retarders available which will give you extra working time beyond the normal 10 - 20 minutes. Another trick is to use cold water. Hot water will speed up the setting process. Also, the more you "work it" the faster it will set. So don't use a power mixer unless you want it to harden in the pail.

I also understand from talking to an oldtimer that "animal glue" (made from bone marrow) used to be mixed in, and that would slow the working time to several hours.

You could try something like carpenters glue. They no longer make it from bone marrow. It's all chemicals and stuff. Not sure if it would work exactly the same, but it's worth a shot.

google fake fruits you can buy small plastic fruits of any kind. if you want to then make a mould from them and cast them in plaster. hope that helps.

Well the glue didn't much work .w.

I used bronco woof glue though.

Regarding the newspaper thing... I made some newspaper strips, dipped them in plaster & then proceeded to wrap it around a model of a mango.

I'm gonna wait till it dries to give you an output =3

Glue didn't work, eh? Just curious. How did you use it?

Did you just add strait glue? Did you mix it with a small amount of water to make the glue runny? Or, did you just add glue after mixing with the regular amount of water?

Some experimentation is usually required with these old timers tricks. The old fellow never did tell me "exactly" how he did things, but I'm suspecting option 1 or 2 is what the guy actually did. Funny thing about these old timers. They'll tell you the secrets, but only enough to get you started. They expect you to figure out the rest!

Then again, I suppose there's always the possibility that the new chemical based glues don't work quite the same as the old animal glues.

Well.

After measuring the water (about 150ml) i added approx. 4 table spoon full of wood glue (approx. Because i just scooped 1 tablespoon of a large spherical goop XD).

Then proceeded to stir until the glue (mostly) dissolved.

After which, i added (300ml, 150ml cups x2) plaster of paris =3

(After at least 34 hours, I tried to reshape the strawberry carrots into more like strawberries. I succeed, but the plaster was incredibly hard than my usual mixtures 0wo)

That's a "technical term" - right? 😈😄

So then, we seem to have had success then!

I'm not surprised it's hard though. That recipe is how they used to make faux marble. Just mix in pigments and you will have what is known as "scagliola."

Ooo OwO
ill make some when i haz time ^w^
Fur now i need to quickly dip some "mangos" in their second batch

Edit: btw, it's actually fine (in my experience) that you could scoop up plaster using your hands even though plaster is known to reach 60° Celsius.

Well i guess if you work fast enough (one way or another since you don't want the plaster to harden & ruin your placement of smooth plaster coating.)
