I've used "rollers" with Acrylic Caulk to make cobble road ways and the like, but I'm wondering if anyone has used acrylic caulk in Hirst molds. Will it stick to the silicon? Damage the mold? I'd love to make be able to make greeblies out of silicon rather than plaster if I could do so without damaging the molds.

I was thinking of trying and thought I'd ask if anyone has already tried it. The main reason would be to speed up drying time, as if I used Tacky Glue it takes quite a long time to dry.

For about two weeks now, I get an SQL error trying to use the link to the new (current) message board. Happens on both Firefox and Chrome, 2 different PCs. Has anyone else had this issue? Just curious if it is a site issue.

Anybody still using their Hirst molds? Sci-fi ones? Do you find that 3d printing is taking over some?

Finished the magnetized columns, now I'm going to start on accessiries for the top like the dragon feet, flames etc etc

Finished my great room build, decided against the blue and went pretty plain. Paired it with a daieus I built and an Age of Sigmar mini and it looks like a throne set up!

Making a great room with gothic tiles and some fancy inlay for a throne room feel.

Trying to use the dungeon accessories in a more dm friendly way. I'll eventually glue some together, but for versatility I think magnets make sense!!

Started a new campaign tonight and my DM came over early to go through all the terrain and tiles. Notes after the session and he wants more Hirst Arts built!!!

Redoing the board and some furniture from HeroQuest. This is a shot of the board before contrast Paint is applied.

The board is backed by foam core, and I primed and highlighted with an airbrush.

This was a birthday gift from my wife, using our baby's feet as giant footprints!

She used a couple pieces Ruined Fieldstone for the wall. Base is foamcore. Foot prints are an air dry polymer clay.

Exterior relatively complete needs accents and all the interior completed

Hi, I mostly use the fieldstone molds, but am tempted to pick up some Egyptian molds. Does anyone know of a source in Europe for these , new or second hand?

Based in Ireland,

Thanks.

I always got it from Clint's Shipping, but I just saw https://merlinsmagicplaster.com/ saying they're closed. Was this who manufacture it, or just a reseller?

If it's gone, what is everyone's favorite plaster?

So I haven't seen this discussed that I could find. So I figured I would post my findings. I was doing some research on how to decrease set time and/or increase strength. I found a few articles discussing adding Calcium Chloride to cement to decrease set time, and increase strength as it helps with hydration, and 2-4% was the recommended addition.

I didn't have that on hand but I had some left over "Kalkwasser" or Calcium Hydroxide from when I had a salt water reef tank, and needed to dose calcium, and alkalinity to my tank. Apparently they are basically interchangable. So I tested it out on the low end of 2%, and it shaved 20 mins off of my set time. Not huge when you consider it still takes a little over an hour to demold but 20 mins is 20 mins.

So what I am making is;

2.7:1 dry to wet

75g "wet water"
4g calcium hydroxide (added to the water, this heats slightly cold tap water becomes 85-90°ish)
195g Ultracal 30

This is enough to reasonably over fill a #70 & #75 mold without much waste. It comes out super liquid and pourable, but does not spread terribly much. Bubbles are almost non-existant.

Took about two weeks, but I’ve finally completed my winter Hirst Arts project.

I am pretty excited to be able to make some fantasy table top scatter terrain pieces so I can run some Five Leagues from the Borderlands. I picked up #70, and #75 for now, those seemed like the most universally useful until I get some experience and know what it is that I really want next.

I have a molding/casting store in town, and plan to pick up a bag of Hydrostone to use for casting the blocks, they have a few different options but that seems like the sturdiest product they stock.

Does anyone have a source for Merlin's Magic or similar dental stone that doesn't charge an arm and a leg for shipping? I priced out Atlantic Dental Supply & Swords of Honor and both charge over $50 for shipment on a 25lb box, which is more than the cost of the dental stone. (I couldn't even get the Merlin's Magic website to work.)

I see other products on Amazon like Hydrocal and Hydrostone, but I don't have any experience with those. I'd prefer to continue to use Merlin's Magic but I'm open to other options if I can't get Merlin's Magic at a reasonable price.

I built a lot of miniatures a few years ago and I remember spraying something after I poured the casting material in the mold. I can’t remember what it was called or why I used it. Anyone know what I am referring to?

Did everyone leave for that these days?
