Gietzand, ook wel vormzand, Brusselse aarde of vettige aarde genoemd is een olie-gebonden mineraal mengsel. Zandgieten is ideaal voor lossende en niet gecompliceerde projecten en een bijkomend pluspunt is dat originele object intact blijft.

Het vormzand is bestand tot een temperatuur van onder nabij de 900°C. Het is dan ook mogelijk om de vettige aarde meerdere malen te gebruiken, mits het bindmiddel nog haar werk doet, samenstelling is namelijk essentieel! Een verkeerde samenstelling kan optreden in de volgende situaties:

  • Vermenging met talkpoeder
  • Thermische belasting welke schifting van de olie veroorzaakt
  • Veroudering van het product (geen zorgen, dit duurt velen jaren)

Wat is zandgieten?

Het zandgieten proces is er geliefd onder smeders, mede door de bijkomende voordelen van de vormzand samenstelling, maar ook door de speciale techniek. Om het zandgieten proces te verduidelijken hebben we hieronder een kort stappenplan voor je opgesteld:

  1. Maak een negatieve afdruk van alle zijden van het object
  2. Haal alle delen los van het object
  3. Plaats de maldelen weer in elkaar en maak ze vast
  4. Je beschikt over een holle mal voor vloeibaar metaal
  5. Pas op met de hitte, na het afkoelen kun je het zwart geblakerde zand verwijderen
  6. Overige vettige aarde kan terug in de zak

Wil je niet teveel vormzand kopen? Gelukkig is hergebruik mogelijk, mits het bindmiddel nog voldoende aanwezig is.

Wij raden het niet aan om het gietzand welke is vermengd met talkpoeder opnieuw te gebruiken, of te vermengen met de verse vettige aarde. Let op, je kunt deze techniek enkel toepassen met lossende objecten.

Gietzand is geschikt voor meerdere materialen

In de meeste gevallen wordt in dit proces gekozen voor brons en aluminium. Het is belangrijk om te onthouden dat het zand tot een maximale temperatuur van 900°C verhit kan worden. De vettige aarde is met name geschikt voor de kleinere en eenvoudigere vormen, denk hierbij aan penningen of munten.

Zelf vormzand maken

Zelf vormzand maken is niet aangeraden, de juiste vormzand samenstelling is namelijk essentieel voor het doen slagen van een project. Ga er in de basis altijd van uit dat het te gieten object lossend dient te zijn en is gemaakt van een niet-vochthoudend materiaal.

Wil je wel een vochthoudend materiaal gieten, bijvoorbeeld een wassen of vochtig klei model, dan is gietzand kopen niet de beste oplossing. Toch op zoek naar een oplossing? Neem gerust contact op met de live chat voor advies.

Slow, sorry but good
Format: Kindle
This was a slow moving book. Lots of character pov chapters, lots of superfluous descriptions and endless courtly appearances stalled this book to start. Once you get into the heart of the story, it takes off. Before you know it the book is done. My favorite character is Reyna. She is so strong. She is true to herself. She gets into a lot of trouble with her headstrong ways but it's entertaining. I have high hopes for Lorcan. He is honorable to a fault. Thane had turned out to be better than I thought but i still don't like him. Eislin is useless. Great plot twists at the end. I'm looking forward too book 2.

Very detailed! Beautiful world building! Strong Heroine!
Format: Kindle
Starts off a little slow and confusing with different POV’s, but starts to all come together towards the middle to make an elaborate plot line and makes it all worth it. Beautiful world building and attention to detail as well as great writing. The cliffhanger was gut wrenching! Can’t wait for the next book!

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love. I can’t wait to read the next one and to complete the series.

Just read it. You won’t regret it.
Format: Hardcover
This book completely blew me away. I loved every single character—not just the FMC and MMC, but the side characters too, which is rare. In a first book, side characters can feel flat while the focus is on world-building, but that definitely wasn’t the case here. The romantic tension between the FMC and MMC was so good—seriously addictive. The plot itself felt pretty straightforward at first, and the world-building was easy to follow. It even gave me Heartless Hunter / Wolf King vibes… until the last 20 pages. And wow—those final pages. I usually spot plot twists coming, and I thought this one was going to be predictable, but I was completely wrong. That ending genuinely shocked me—I haven’t had that reaction to a book in a long time. I’m already counting down to book two (and that teaser chapter? Absolutely brutal). Just read it. You won’t regret it.

4 Stars for Now!
Format: Kindle
I DEVOURED this book. I was in a huge slump after reading a horrible series right before this but after 3 pages of this book, I was hooked. I read the whole book in 2 days. I think the author did an amazing job at writing an engaging story with an amazing twist at the end. I know many readers feel betrayed by the twist and find the narrator to be unreliable but I feel that the twist was done in a great unsuspecting way. Though I do feel betrayed, I think there is so much room for redemption in the second book! The author also did an amazing job at world/character building. She was able to do so without interrupting the story which is one of my huge pet peeves. A lot of authors build by taking breaks in the plot or dialogue which I find choppy and disengaging but this author was able to build in an engaging way. There was some lack of world/character building but I think that was due to keeping reader in the dark. The world, politics, and characters were all very easy to understand. I found the romance a little lackluster and a bit off-kilter. Some of it was really pushy and rushed which left a bad taste in my mouth. I do hope the author delves deeper into the romance in coming books. The FMC was a breath of fresh air. She was not whiny or stuck-up like most books. She was never afraid to accept help from others but she was still able to shine with her intelligence. Not once did I think she made a poor decision just for the sake of a plot point. She was really easy to like. The MMC could use some work but I think that will happen more in coming books. This is a MUST read, my only advice would be to wait until it is a finished series!
