How to Weigh, Mix, and Pour Plaster for Slip Casting - GUY MICHAEL DAVIS

In this video clip, an excerpt from his video, Fundamentals of Mold Making and Slipcasting, Guy Michael Davis walks us through the steps for mixing plaster and pouring a one piece mold. This video is available in the Ceramic Arts Network Shop: mycan.ceramica...

Yes, whoever created the ratio chart, missed the decimal point - should read: PLASTER ------ > WATER 10 lbs 7 lbs 5 lbs 3.5 lbs 2.5 lbs 1.75 lbs 1.25 lbs .875 lbs

[@jimpinney]

would this ratio work with latex statues molds smaller ones under 6 inchs

[@colindavis2113]

Thanks. I was like what the heck man?

[@regularguy8592]

@@colindavis2113 so glad you posted this I was like wtf trying to figure that chart out

I use a tamis to sift my plaster into the water, and then mix by hand. This gentle agitation drives out bubbles. Maybe it was in a different video, but Mr. Davis forgot to mention spraying or coating the object with a surfactant to help prevent bubbles from adhering to the surface of the object.

[@PrissyArtDept]

What surfactant do u use?

[@paulmatthews1346]

this was really helpful, thank you

When wearing a dust mask, make sure you shave or else it is useless. And only wearing it for only 2 minutes is also counter productive. Dust lingers in the air for much longer.

[@Juanguaqueta]

Would you please let me know what is the function of those forceps on the tables? I am new to this. Best regards.

[@disisdkat]

the decimal point is not showing which is a Whoa - that can't be right (5lbs plaster to 35lbs water...)

[@disisdkat]

Yes I know it should be obvious from what the other measures are. It just caught my eye and amused me (at my own response).

[@saynaparsi6156]

How do you clean the plaster mixing bucket and mixing tools?

[@AlvaSudden]

If I mixed that much air into my plaster, I would have problems.

[@goneviral6037]

Take weight pounds x .70 get weight of water needed

[@ele4853]

Good job sir! Do you have any tip on where to buy KT 1-4 Kentucky Ball Clay?

[@micheledickey4066]

Isn’t the purpose to NOT add any more air than you need to?!

[@josephina4792]

What is the bottle of glue for? Do you add it to the plaster?

[@dawnbeasley8897]

Capsulend Capsulend The glue is still on the table from his last demo on making cottle boards

[@NabilElJaouhari]

Can you use Hydrocal? Thank you

[@henkengelbrecht173]

What is a 6 by 6 cube? last time I checked that would give area not volume.

[@Alexander-rq9he]

He misspoke. Simply saying a 6” cube would be sufficient.

[@darkussolace4335]

6x6 what? inches? meters?

[@jerrywhidby5259]

sol malana I was wondering about 6x6 at what depth? Thick? Thin?

[@codythomas7180]

I know this is a year late, but it's in inches

[@alirezaarab4071]

they use odd measurement systems. could be deer

[@mhb-hz9ud]

😍

[@DeanLeatherman]

Inane videography. What does showing the guy's ear tell us about mixing plaster. Why did the guy write out the chart? Why didn't you just zoom in on that instead of posting something that was hilariously wrong?
