  	In this article, our Dunja takes us behind the science of acrylic paints!
  
  	Acrylic paints – high pigment content and good coverage. If they are well formulated, they stay where you apply them, don't leave "brush marks" and dry slowly enough to do what you want on the miniature, yet still fast enough.
  
  	
  
  	Composition:
  
  	
  
  		Binders (eng. resin) – form a film – in our case probably pure acrylates, I suspect they are styrene acrylates.
  	
  
  		Fillers – in addition to adding volume to the paint, they also affect the viscosity, coverage and appearance of the dry film
  	
  
  		Pigments – the main division is into organic pigments and inorganic pigments. Inorganic ones are more covering but have less vivid shades, while organic ones are often quite poorly covering (yellow for example) but their shades are vivid and bright
  
  
  	Additives:
  
  	
  
  		Anti-foam
  	
  
  		Rheological modifiers – affect the behavior of wet paint on the substrate (e.g. spillage) and the behavior of the paint when a force is applied to it (brush, roller, spray, airbrush). Rheological modifiers also include thickeners that affect the viscosity of the paint.
  	
  
  		Dispersants – envelop pigment and filler particles and prevent their agglomeration during standing. Good dispersion of pigment and filler affects the coverage and uniform appearance of the dry film. There are a bunch more but I won't go into too much detail
  	
  
  		Solvent – ​​in this case water.
  
  
  	Contrast paints and speed paints – high pigment content, but not so much that it causes high coverage. They are formulated to spread, not to stay where you put them. The result of spreading is that the paint collects in the recesses, where a thicker film of paint remains than on the protruding parts of the miniature. Where the film of paint is thicker (the recesses), the shade of the contrast paint is more pronounced, unlike on the protruding parts where the film is thinner, which is why the shade is then influenced by the color of the substrate.
  
  	
  
  	 
  
  	Composition:
  
  	
  
  		Binders
  	
  
  		Pigments
  	
  
  		Additives – all listed above + surfactants that reduce the surface tension of the wet paint film, which is why it flows
  	
  
  		solvent
  	
  
  		I would say they do not contain fillers, or contain very, very little of them
  
  
  	 
  
  	Washes – similar in formulation and behavior to contrast agents, only they have a much lower proportion of pigments, certainly no fillers, a higher proportion of surfactants, lower viscosity, and probably less binders.
  
  	
  
  	If we want to greatly dilute acrylic paint or contrast, it is better to use a product intended for this purpose from the manufacturer of that paint rather than water, because it contains all the necessary amount of binders and additives for that paint to retain its properties.

  	U ovom članku, naša Dunja nam otkriva znanost iza akrilnih boja.
  
  	Akrilne boje – visoki udio pigmenta i dobra pokrivnost. Ako su dobro formulirane ostaju tamo gdje ih naneseš, ne ostavljaju „brush marks“ i suše se dovoljno sporo da stigneš napravit što želiš na minijaturi a opet dovoljno brzo.
  
  	
  
  	Sastav:
  
  	
  
  		Veziva (eng. resin) – formiraju film – u našem slučaju vjerojatno čisti akrilati, sumnjam da su stiren akrilati.
  	
  
  		Punila – osim što dodaju volumen boji utječu i na viskoznost, pokrivnost i izgled suhog filma
  	
  
  		Pigmenti – glavna podjela je na organske pigmente i anorganske pigmente. Anorganski su više pokrivni ali manje živih nijansi, dok su organski često dosta loše pokrivni (žuti npr) ali zato su im nijanse žive i jarke
  
  
  	Aditivi:
  
  	
  
  		Protiv pjene
  	
  
  		Reološki modifikatori – utječu na ponašanje mokre boje na podlozi (npr razlijevanje) i na ponašanje boje dok na nju djeluje sila (kist, valjak, sprej, airbrush). Pod reološke modifikatore spadaju i ugušćivači koji utječu na viskozitet boje.
  	
  
  		Dispergatori – obavijaju čestice pigmenata i punila i sprječavaju aglomeraciju istih stajanjem. Dobra dispergiranost pigmenta i punila utječe na pokrivnost i ujednačen izgled suhog filma.
  	
  
  		Ima ih još hrpa ali neću toliko u detalje
  	
  
  		Otapalo – u ovom slučaju voda.
  
  
  	Kontrastice i speed paints – visoki udio pigmenta, ali ne toliki da uzrokuje visoku pokrivnost. Formulirane su da se razlijevaju, a ne da ostaju tamo gdje ih staviš. Posljedica razlijevanja je skupljanje boje u udubine gdje onda ostane deblji film boje nego na isturenim dijelovima minijature. Tamo gdje je film boje deblji (udubine) nijansa kontrastice izraženija, za razliku od isturenih dijelova na kojima je film tanji zbog čega na nijansu onda utječe boja podloge.
  
  	
  
  	Sastav:
  
  	
  
  		Veziva
  	
  
  		Pigmenti
  	
  
  		Aditivi – svi nabrojani gore +
  	
  
  		surfakanti koji smanjuju površinsku napetost mokrog filma boje zbog čega i dolazi do razlijevanja
  	
  
  		otapalo
  	
  
  		rekla bih da ne sadrže punila, ili ih sadrže vrlo vrlo malo
  
  
  	 
  
  	Washevi – po principu formuliranja i ponašanju slični kontrasticama, samo imaju puno manji udio pigmenata, sigurno ne sadrže punila, veći udio surfakanata, manji viskozitet i vjerojatno manje veziva.
  
  	
  
  	Ako želimo jako razrijediti akrilnu boju ili kontrasticu bolje je koristiti za to predviđen proizvod od proizvođača te boje nego vodu, jer sadrži svu potrebnu količinu veziva i aditiva kako bi ta boja zadržala svoja svojstva.

• Tabla za Necropolis – dio 1

  	In October we started with our first board for Necropolis, and with an appropriate theme! – the Eternal Autumn configuration from the Necropolis rulebook. The configuration is such that it only requires 3 trees, which we considered too boring, so instead of one tree, we plan to build a cubic lime kiln and 2 streams.
  
  	  
  
  	The board is inspired by Hawthorne's story Ethan Brand, where several characters talk about the unforgivable sin (next to a lime kiln in the middle of an American pastoral idyll). Aesthetically, we're aiming for early fall with rural motifs, along with gnarled trees (ala Burton's Sleepy Hollow) and a few pumpkins.
  
  	  
  
  	For now, we are very far from any aesthetic choices because we have dealt with the basic structure of the board: the housing is made of pine glued boards for the floor and pine profiles for the sides. After we glued everything with Drvofix, the entire housing was finely sanded. The size of the Styrodur board that fits into the housing is 40cmx40cmx2cm (Necropolis standard is 16"x16").
  
  	  
  
  	The placement of the stream itself was difficult to choose due to the peculiar, angular deployment in Necropolis, so we used token strings to try out a few potential streams that would least interfere with the game. Although we planned to keep our forest streams shallow, we still carved channels with a scalpel and a rotary multitool and coated the beds with diluted texture paste. While the paste dried, we added various sizes of pebbles and created a transition across the stream with larger pebbles.
  
  	  
  
  	The trees are actually real mangroves, so they have natural knots and twists. To add a Sleepy Hollow feel, we hollowed out a few holes in the wood to house the greenstuff faces. We propped up one tree with pieces of pine bark so it wouldn't lean too much and interfere with play.
  
  	  
  
  	The next step is to cover the entire board with a mixture of gypsum and sand and make the stove itself.
  
  	  
  "
      ["content_hrv"]=>
      string(4295) "
  
  	  
  
  	U listopadu smo započeli s našim prvim boardom za Necropolis, i to s primjerenom tematikom! – Eternal Autumn konfiguracijom iz Necropolis rulebooka. Konfiguracija je takva da nalaže samo 3 stabla, što smo smatrali predosadnim te umjesto jednog stabla kanimo izraditi kockastu vapnenu peć i 2 potoka.
  
  	  
  
  	Board je inspiriran Hawthorneovom pričom Ethan Brand, gdje nekoliko likova priča o neoprostivom grijehu (pored vapnare usred američke pastoralne idile). Estetski ciljamo na ranu jesen s ruralnim motivima, uz kvrgava stabla (ala Burtonov Sleepy Hollow) i nekoliko bundeva.
  
  	  
  
  	Za sada smo jako daleko od ikakvih estetskih odabira jer smo se nosili s osnovnom građom boarda: kućište je napravljeno od borovih lijepljenih dasaka za podni dio i borovih profila za bočne strane. Nakon što smo sve zalijepili drvofixom, cijelo kućište je fino izbrušeno. Veličina stirodur ploče koja sjeda u kućište je 40cmx40cmx2cm (Necropolis standard je 16“x16“).
  
  	  
  
  	Sami smještaj potoka bilo je teško odabrati zbog osebujnog, kutnog deploymenta u Necropolisu pa smo koristili nizove tokena da isprobamo nekoliko potencijalnih tokova koji bi najmanje ometali igru. Iako planiramo da nam šumski potoci budu plitki, i dalje smo skalpelom i rotirajućim multitoolom izrezbarili kanale i premazali korita razrijeđenom teksturnom pastom. Dok se pasta sušila, ubacili smo razne veličine kamenčića i uspostavili prijelaz preko potoka većim kamenčićima.
  
  	  
  
  	Stabla su zapravo pravo mangrovo drvo, tako da ima prirodne kvrge i zavijutke. Kako bismo dodali sleepy hollow šmek, izdubili smo nekolika rupa u drvu gdje bismo smjestili greenstuff lica. Jedno smo drvo poduprli s komadima borove kore kako ne bi bilo previše nagnuti i ometalo igru.
  
  	  
  
  	Sljedeći korak je prekrivanje cijelog boarda smjesom gipsa i pijeska te izrada same peći.

  	In early October I had the opportunity to visit my neighbors from the Amuletd20 association. This time it wasn't an artsy Turnip28 event, but a huge tournament in AOS and Conquest games.
  
  	  
  
  	Besides the main event, there were tables playing Kings of War, as well as Warhammer: The Old World, where I came with my Chaos Dwarfs.
  
  	  
  
  	Unfortunately, I think TOW was the least represented with four players, but this little community was wonderful! Players helped each other with the rules and the games were very friendly. In addition to my choirs, there was also an army of High Elves at the event, as well as two armies of Brettons.
  
  	  
  
  	  
  
  	  
  
  	I spent my event fighting the noble knights of Brettonia, and I believe that my dwarves were helped by the atypical mobility obtained from the monsters (Wyverna, Lammasu and Bale Taurus) accompanied by the antithesis of HŽ (Iron Daemon) and a spell that increased the infantry's mobility.
  
  	  
  
  	The Kings of War tables were much more dynamic, with more players, more games, and the waxes themselves were far more diverse. I'm glad that the tables were close so I had the opportunity to hang out with the hosts Luka and Vane.. It was definitely a surprise when our Mario visited us and hung out with us.
  
  	  
  
  	I managed to find enough time to walk around the rest of the event - and it was impressive to see so many players in one place. Amuletd20 really did a phenomenal job for their first event.
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	After the event, we went to the association's premises to socialize a little more. And, if you're curious about what it was like there, come to the next Amulet event yourself, you certainly won't regret it.
  
  	  
  
  	P.S. Many thanks to Luka, Vana and Mita for the invitation and hospitality!

  	Početkom listopada imao sam priliku posjetiti susjede iz udruge Amuletd20. Ovog puta nije bio artsy Turnip28 event, nego ogroman turnir u AOS i Conquest igrama.
  
  	  
  
  	Osim main eventa, bilo je stolova na kojima se igralo i Kings of War, kao i Warhammer: The Old World gdje sam došao sa svojim Chaos Dwarfovima.
  
  	  
  
  	Nažalost, mislim da je TOW bio najslabije zastupljen s četiri igrača, ali je ovaj mali community bio divan! Igrači su si međusobno pomagali s pravilima i partije su bile jako Friendly, Uz moje chorfove, na eventu je bila i jedna vojska High Elfova, kao i dvije vojske Brettonaca.
  
  	  
  
  	  
  
  	  
  
  	Svoj event proveo sam boreći se plemenitim vitezovima Brettonie, a vjerujem da je mojim patuljcima pomogla netipična mobilnost dobivena čudovištima (Wyverna, Lammasu i Bale Taurus) u pratnji antiteze HŽ-a (Iron Daemon) i čarolije koja je pješadiji povećavala mobilnost.
  
  	  
  
  	Na Kings of War stolovima bilo je znatno dinamičnije, više igrača, više partija, a i same vosjke su bile daleko raznolikije. Drago mi je da su stolovi bili blizu pa sam imao priliku družiti se s domaćinima Lukom i Vaneom.. Definitivno iznenađenje je bilo kad nas je naš Mario posjetio i podružio se s nama.
  
  	  
  
  	Uspio sam uhvatiti dovoljno vremena da prošećem i ostatkom eventa - i bilo je impresivno vidjeti toliko igrača na istom mjestu. Amuletd20 je zaista odradio fenomenalan posao za prvi event koji organiziraju.
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	  
  
  	Nakon eventa, otišli smo do prostora udruge podružiti se još malo. A, ako vas zanima kako je tamo bilo, dođite i sami na idući Amuletov event, sigurno nećete požaliti.
  
  	  
  
  	P.S. Veliko hvala Luki, Vani i Miti na pozivu i gostoprimstvu!

  	During October and November, we held our Back to Basics miniature painting workshops for the youngest at the Zagreb City Libraries.
  
  	
  
  	
  
  	The first set of three workshops was held in the Youth Department of the Medveščak Library on October 2, 9 and 11, 2025.
  
  	
  
  	
  
  	During the workshops, our youngest participants painted chibi figures from the UMS Agram line and made a castle from upcycled materials.
