The best way to frame a charcoal drawing is to use archival-quality materials and a method that minimizes dust fallout and protects the artwork. This involves proper hinging to the backing board, rather than the mount board.
Understanding the Challenges of Framing Charcoal Drawings
Charcoal, by its nature, is a fragile medium. It tends to smudge and release particles, which can lead to the drawing deteriorating over time and dust accumulating inside the frame. Proper framing techniques are therefore crucial for preservation.
Recommended Framing Techniques
Here's a breakdown of the best practices for framing charcoal drawings:
-
Archival-Quality Materials are Essential: Only use acid-free materials for everything that comes into contact with the artwork. This includes the backing board, mat board (if used), hinging tape, and adhesive. Acid can degrade the paper and charcoal over time.
-
Hinging to the Backing Board: The crucial step is to attach the drawing to the backing board instead of the mount board. Use one of the following methods:
- T-Hinges: Create T-shaped hinges from acid-free Japanese paper (washi) or linen tape. Adhere the short part of the "T" to the back of the drawing and the long part to the backing board.
- V-Hinges: Similar to T-hinges, but the paper or tape is folded in a "V" shape to provide more flexibility.
- Acid-Free Photo Corners: These are a non-adhesive option that gently holds the corners of the drawing in place.
-
Why Hinging to the Backing Board Matters: Attaching the drawing to the backing board allows it to expand and contract with changes in humidity without putting stress on the drawing itself or causing it to rub against the mat board. This helps minimize dust and smudging.
-
Mat Board (Optional but Recommended): A mat board creates space between the drawing and the glass or acrylic, preventing smudging and offering an extra layer of protection. Choose an acid-free, lignin-free mat board.
-
Glazing (Glass or Acrylic): Glazing protects the drawing from dust, moisture, and UV light.
- Glass: Offers excellent clarity but can be heavy and fragile. Consider UV-protective glass to minimize fading.
- Acrylic: Lightweight and shatter-resistant, but can scratch more easily than glass. Opt for museum-grade acrylic, which offers UV protection and anti-static properties. Avoid using regular acrylic directly against the charcoal as static can lift the charcoal from the paper.
-
Sealing the Frame: After assembling the frame, seal the back with archival-quality tape to prevent dust and insects from entering.
Step-by-Step Framing Process
- Prepare the Backing Board: Cut an acid-free backing board to the size of the frame's inner dimensions.
- Attach the Drawing: Using your chosen hinging method (T-hinges, V-hinges, or photo corners), attach the drawing to the backing board. Position the drawing carefully, allowing for even margins.
- Place the Mat Board (if using): Place the acid-free mat board on top of the drawing and backing board.
- Clean the Glazing: Thoroughly clean the glass or acrylic to remove any dust or smudges.
- Assemble the Frame: Carefully insert the backing board, drawing, mat board (if using), and glazing into the frame.
- Seal the Back: Seal the back of the frame with archival-quality tape.
Final Considerations
- UV Protection: Consider using UV-protective glazing to minimize fading, especially if the drawing will be exposed to direct sunlight.
- Professional Framing: If you are unsure about any of these steps, consider having your charcoal drawing professionally framed. A professional framer will have the expertise and materials to ensure the drawing is properly preserved.
