Alright, I want to qualify this by saying I'm 100% certain this has been asked before, but I'm just too green to understand what I'm reading and not sure where to go from here. Lets start off by...

Thanks again, Galileo. Im on their site, which is decidedly not mobile friendly. (Doesn't show local distributors at all). It does say (and half dozen other sites I've checked now as well) that the...

With Hydrostone, mechanical mixing is recommended for large batches (gallons at a time). At the small scale we're dealing with, it's not a problem.

As for getting the materials, being your in LA might be of an advantage to you. You need to visit Rynolds Advanced Materials to pick up your plasters (0856 Vanowen St North Hollywood, CA 91605) if...

Kovax, thanks!! this is a huge help, as the ominous "machine mix only" for a dental die that is specifically meant for making something the size of my fist.... Seemed like a big deal. This solves up...

http://www.hirstarts.com/casting/dental.html It has the chart for Merlin's to water by weight - roughly 3 parts plaster to 1 part water. Might be a good starting point - adjust as necessary

Hahaha thanks again, yes I saw that link and that's where I got my rough proportions from. But someone in the casting techniques page suggested they have an excell spreadsheet that lists exact volumes...

You're overthinking it. I mix a batch of Merlin's exactly as listed on that link. I pour the pieces I want (usually have 5 molds on the board) and then the leftover goes into whatever I think I need...

I'm sure you're right. I just dropped $1k on molds, $50 on scales and dehydrators and glue, and I'll be hitting Reynolds tomorrow for likely $100 in plaster. So, over thinking trying to ensure...

After the first few dozen pours, you'll start ending up with piles of pieces that you have no need for, or only need one or two instead of dozens. That's why I generally mix roughly enough plaster...

Oh I was planning mixing batch by batch for a maybe two molds tops, and since I'm starting off with nothing, spare pieces won't be a problem as I have tons of projects I can do i totally get get the...

You are really over thinking it. Ever make Jello Pudding? Measure out milk, add in powder mix, stir until lumps are gone, pour into service dishes, chill... very much the same principle with making...

That is certainly an issue. I don't have a designated work space, so I'm going to be doing this whenever I have time and a foot or so of room. i went to Reynolds today and got a 100# bag of hydrocal...

So I'd like to thank everyone for their two cents so far. I mixed up and had a pour party today. Made 250ml batch at about 1:1. It was a bit thin, but for a first shot I felt I did well. I did pop...

I used the scrape method for over a year. Once I tried the plexiglass method, my scraper now has a lot of dust built up on it. I first started out using large cans of soups and vegetables for my...

Ultimately, this is at least as much of an art as it is a science, so beyond the basics, the only way you're going to learn and improve is through practice. Glad to hear that your first batch was...

I went through around 1.5L of mix (total volume) today. Made about a dozen separate molds, and some partials. Played with different ratios from .8 plaster to 1 water all the way through 1.25 plaster...

I am not aware of any gypsum product that is "chip proof." I've used a lot of them, including Excalibur and Hydrostone. I use Hydrostone as the best compromise between availability, durability and...
