( 그림공부 ) 과슈( Gouache) 는 어떤 물감인가

Poppy Balser, “Evening Light on Water and Stone,” Gouache on paper, 8×10 inches; winner in the  PleinAir Salon  (September 2024, Best Plein Air Watercolor & Gouache),  www.poppybalser.com “I chose to use gouache on watercolor board,” Poppy said. “That allowed me to start with the dark background and shaded parts of the water. From there I started to add the rocks in the stream and the warm colors of the water. I painted the light golden and reddish-brown parts of the water quite transparently, to help imitate the sense of light shining through the water. Then I dragged the blue of the sky across afterward to suggest the ripples in the moving water.”

 

Poppy Balser, "Evening Light on Water and Stone",

종이에 구아슈, 8×10인치; PleinAir Salon(2024년 9월, 최우수 Plein Air Watercolor & Gouache 부문) 수상,

"저는 수채화 보드에 구아슈를 사용하기로 했습니다."라고 Poppy가 말했습니다.

 "그러면 어두운 배경과 물의 그늘진 부분부터 시작할 수 있었습니다. 

거기에서 개울 속의 바위와 물의 따뜻한 색상을 추가하기 시작했습니다. 

물의 밝은 황금색과 적갈색 부분을 매우 투명하게 칠하여 물 속을 통해 비치는 

빛의 감각을 모방했습니다. 그런 다음 움직이는 물의 잔물결을 표현하기 위해 하늘의 파란색을 

그렸습니다."

Realism Today mail 에 Gouache 에 대한 짧은 강의내용이 있어 옮긴다

과슈란 미디움이 궁금하여 가장 기본적인 파레트 하나 구매해서

사용은 해보았는데 아직 과슈의 장점을 제대로 모르다보니 그냥 놔두고 있다.

다시 한번 과슈를 이용해서 그림을 시도해 봐야겠다.

구아슈라는 단어가 원래 진흙을 뜻하는 이탈리아어 Guazzo에서 유래했다는 걸 알고 계셨나요? 

구아슈가 수채화보다 색소가 더 많다는 걸 알고 계셨나요? 

불투명 수채화라고도 하는 구아슈는 풍부한 역사와 독특한 작업 특성을 가지고 있어 

진정으로 독창적인 예술가 소재입니다. 

Royal Talens 미술 교육 책임자인 Jeff Olson과 함께 구아슈의 역사, 특징, 응용 분야를 

탐구하고 예술 활동에 어떻게 통합할 수 있는지에 대한 영감을 주는 여정에 참여하세요.

요약:

풍부한 역사와 독특한 특성으로 수세기 동안 예술가들을 사로잡아 온 매체인 구아슈의 

활기찬 세계에 오신 것을 환영합니다. 오늘은 매력적이고 통찰력 있는 프레젠테이션으로 

유명한 사랑받는 미술 교육자 Jeff Olson과 함께 구아슈의 심층적인 내용을 살펴보겠습니다. 

노련한 예술가이든 호기심 많은 초보자이든 Jeff의 전문 지식이 이 매혹적인 매체의 미묘한 뉘앙스를 

안내해 드립니다.

역사적 여정
구아슈는 종종 불투명 수채화라고도 불리며, 고대로 거슬러 올라가는 유서 깊은 역사를 

가지고 있습니다. 그 기원은 고대 그리스 테라코타 그림과 페르시아 미니어처에서 

찾을 수 있는데, 복잡한 세부 묘사를 만들어낼 수 있는 능력 때문에 예술가들에게 

선호되는 선택이었습니다. 르네상스 시대로 넘어가면서 알브레히트 뒤러와 같은 예술가들은 

구아슈와 수채화를 결합하여 놀라운 식물 그림을 만들기 시작했습니다.

18세기는 구아슈의 전성기였으며, 특히 프랑스에서는 종종 파스텔과 함께 사용되었습니다. 

이 조합을 통해 예술가들은 생생하고 세부적인 초상화를 만들 수 있었고, 

이 기술은 오늘날에도 계속되고 있습니다. 19세기와 20세기에 들어서면서 구아슈는 

다재다능함과 생생한 색상으로 인해 인상파와 디자이너의 팔레트에서 자리를 잡았습니다.

 

구아슈의 구성
구아슈는 기본적으로 수채화와 비슷하지만 비율이 다른 안료와 바인더로 구성되어 있습니다. 

이 독특한 구성은 구아슈에 독특한 불투명도와 생생한 색상을 부여합니다. 

구아슈에 사용되는 안료는 유기, 무기 및 합성 공급원을 포함한 다양한 출처에서 공급됩니다. 

이러한 안료 공급원의 다양성은 광범위한 색상과 효과를 허용합니다.

아라비아 검과 덱스트린은 구아슈에 사용되는 주요 바인더로, 

각각 매체의 특정 작업 특성에 기여합니다. 이러한 바인더는 안료를 현탁시키는 데 

도움이 될 뿐만 아니라 페인트가 표면에 잘 부착되도록 하여 구아슈를 아티스트에게 다재다능한 

선택으로 만듭니다.

구아슈 작업
구아슈의 가장 매력적인 특징 중 하나는 편의성입니다. 튜브와 팬으로 제공되는 

구아슈는 운반 및 사용이 쉽고 활성화하는 데 물만 필요합니다. 

건조 시간이 빠르기 때문에 빠르게 작업하거나 효율적으로 색상을 겹치려는 아티스트에게 

이상적입니다.

구아슈의 불투명도 덕분에 아티스트는 어두운 색 위에 밝은 색을 겹쳐 칠할 수 있는데, 

이는 전통적인 수채화에서는 불가능한 기술입니다. 그러나 아티스트는 구아슈가 마르면서 

밝은 색이 어두워지고 어두운 색이 밝아지는 색상 변화를 알고 있어야 합니다. 

이러한 특성으로 인해 아티스트는 색상 혼합 및 적용에 대한 접근 방식을 조정해야 합니다.

성공을 위한 팁
작은 규모로 시작: 더 큰 프로젝트를 시작하기 전에 매체에 대한 감각을 익히기 위해 

작은 구성으로 시작하세요.
팔레트 제한: 제한된 색상 팔레트는 창의성을 장려하고 색상 혼합을 더 쉽게 해줍니다.
큰 획 사용: 세부 사항을 추가하기 전에 큰 브러시로 색상을 블록으로 칠하여 구성을 확립하세요.
명암 고려: 색상 변화를 염두에 두고 원하는 효과를 얻기 위해 값을 과장하세요.
겹쳐 칠하기: 각 층이 마르도록 한 다음 다음 층을 적용하여 더 깨끗하고 선명한 결과를 얻으세요.
아크릴 구아슈 탐색
아크릴 구아슈는 아티스트에게 두 가지 장점을 제공합니다. 

전통적인 구아슈의 무광 마감과 아크릴의 영구성을 모두 제공합니다. 바인더로 아크릴 폴리머 

에멀전을 사용하는 아크릴 구아슈는 마르면 방수가 되어 레이어링과 표면 선택에 더 많은 유연성을 

제공합니다.

전통적인 구아슈와 일부 특성을 공유하지만 아크릴 구아슈의 고유한 특성으로 인해 

모든 아티스트의 도구 키트에 귀중한 추가품이 되며, 특히 구아슈의 모양을 좋아하지만 

아크릴의 내구성을 원하는 사람들에게 그렇습니다.

결론
구아슈는 예술적 표현에 무한한 가능성을 제공하는 다재다능하고 보람 있는 매체입니다. 

풍부한 역사나 현대적인 응용 분야에 끌리든 구아슈는 불투명도, 생동감, 편의성의 

독특한 조합을 제공합니다. 이 Art School Live 프레젠테이션( 아래) 에서

Did you know the word gouache comes from the Italian Guazzo, whose original meaning was mud? Did you know that gouache has more pigment than watercolor? Gouache, also referred to as opaque watercolor, has a rich history and unique working properties that make it a truly original artists material. Join Royal Talens Art Education Director, Jeff Olson, for an inspiring journey exploring the history, features, and applications of gouache and how you can incorporate it into your artistic practice.

 

Summary:

Welcome to the vibrant world of gouache, a medium that has captivated artists for centuries with its rich history and unique properties. Today, we are diving into the depths of gouache with none other than Jeff Olson, a beloved art educator known for his engaging and insightful presentations. Whether you’re a seasoned artist or a curious beginner, Jeff’s expertise will guide you through the nuances of this fascinating medium.

A Historical Journey

Gouache, often referred to as opaque watercolor, has a storied past that dates back to ancient times. Its origins can be traced to ancient Greek terracotta paintings and Persian Miniatures, where its ability to produce intricate details made it a preferred choice for artists. Fast forward to the Renaissance, and artists like Albrecht Dürer began combining gouache with watercolor to create stunning botanical illustrations.

The 18th century marked the heyday of gouache, especially in France, where it was often paired with pastel. This combination allowed artists to create vibrant and detailed portraits, a technique that persists even today. As we moved into the 19th and 20th centuries, gouache found its place in the palettes of impressionists and designers, valued for its versatility and vibrant colors.

 

The Composition of Gouache

At its core, gouache is composed of pigment and binder, similar to watercolor, but in different ratios. This unique composition gives gouache its distinctive opacity and vibrant color. The pigments used in gouache are sourced from a variety of origins, including organic, inorganic, and synthetic sources. This diversity in pigment sources allows for a wide range of colors and effects.

Gum arabic and dextrin are the primary binders used in gouache, each contributing to the medium’s specific working properties. These binders not only help suspend the pigment but also ensure the paint adheres well to the surface, making gouache a versatile choice for artists.

 

Working with Gouache

One of the most attractive features of gouache is its convenience. Available in tubes and pans, gouache is easy to transport and use, requiring only water to activate. Its quick drying time makes it ideal for artists who want to work rapidly or layer colors efficiently.

Gouache’s opacity allows artists to layer light over dark, a technique not possible with traditional watercolor. However, artists should be aware of the color shift that occurs as gouache dries, with light colors becoming darker and dark colors becoming lighter. This characteristic requires artists to adjust their approach to color mixing and application.

Tips for Success

• Start Small: Begin with small compositions to get a feel for the medium before tackling larger projects.
• Limit Your Palette: A limited color palette encourages creativity and allows for easier color mixing.
• Use Big Strokes: Block in colors with large brushes to establish the composition before adding details.
• Consider Your Values: Be mindful of the color shift and exaggerate values to achieve the desired effect.
• Layering: Allow each layer to dry before applying the next for cleaner, crisper results.

Exploring Acrylic Gouache

Acrylic gouache offers artists the best of both worlds: the matte finish of traditional gouache with the permanence of acrylics. Using an acrylic polymer emulsion as its binder, acrylic gouache is waterproof once dry, allowing for more flexibility in layering and surface choice.

While it shares some characteristics with traditional gouache, acrylic gouache’s unique properties make it a valuable addition to any artist’s toolkit, especially for those who appreciate the look of gouache but desire the durability of acrylics.

Conclusion

Gouache is a versatile and rewarding medium that offers endless possibilities for artistic expression. Whether you’re drawn to its rich history or its modern applications, gouache provides a unique blend of opacity, vibrancy, and convenience. With Jeff Olson’s guidance in this Art School Live presentation (above), you’re now equipped with the knowledge to explore this medium and incorporate it into your own artistic practice.
