Egg tempera has been practiced by artists for over two thousand years. It is one of the most durable and beautiful paints in the history of art. Students will discover how master practitioners of this art form prepared their pigments from the earth, rocks and plants and mixed with egg yolk to make their tempera paint.

This qualification aims to provide expert guidance to learners wishing to gain knowledge and understanding on Electric Vehicle charging equipment installation. This 2 day course provides expert guidance on EV charging equipment installation, an important emerging area which is not covered in detail by the current edition of the Wiring Regulations (BS 7671) or the IET’s Guidance Notes. Aimed at experienced electricians interested in understanding a wide range of equipment and systems available, this course applies to the specialised installation requirements of electric vehicle charging equipment in domestic dwellings, on-street locations, commercial and industrial premises. The course provides detailed guidance and recommendations on all aspects of the installation of Electric Vehicle Charging Equipment from the origin of the electrical supply, through distribution and final circuits, installation of the charging equipment itself to the cable between the charging equipment and vehicle’s electrical inlet. Also included are related issues of site layout and planning and subsequent inspection, testing, certification and maintenance of installations. Why take this course? Currently there is an increasing demand for new electric vehicle charging points but too few installers to roll them out. This is already a booming market which is due to get much bigger in the near future. The number of public charging connectors and locations has increased by 38% in the past 12 months and is expected to continue at that rate for years to come. Entry Requirements There are no formal entry requirements for this qualification, however we do expect you to meet the following requirements: Minimum age 18 years old (mandatory) Must be able to demonstrate the following competencies Be able to correctly install and terminate: pvc/pvc cable (twin and earth) Steel Wire armoured cable (swa) Be able to carry out an initial verification (inspection & testing) on an electrical installation and complete the necessary paperwork. Please Note: These competencies are required for the assessment and are not taught as part of the course. It is also recommended that you are up to date with your wiring regulations.

Join us on a journey through the geometric arts of Ancient Egypt ... The profound relationship between qualitative geometry and the forms of architecture and sculpture is no where better expressed than in the ancient egyptian tradition. During this course we will be drawing inspiration from the work of R.A. Schwaller de Lubitcz, John Michell and others. The philosophical implications of the golden section in Egyptian art will be covered. The Pyramids: the pyramids and earth measure - we will draw and model the great pyramid of Giza to scale.

Part 1, October 27th -29th, 2023 @ Clophill The Spiral continues – Four modules going around the cardinal directions West Direction – October 27th – 29th, 2023 With Leo Rutherford & Ruth Humming Ford Mother Earth – Life, Death and the Dance!  This module is focussed on the Earth and our connection to everything physical – in other words, every-THING! This includes our own body which is our spirit's 'Vehicle of-Experience' for this life on earth. The shamanic path is about developing our personal sovereignty, our right to Real-ise our True Self.   Our movement West is towards our fitness to navigate our way through this life and into the beyond. The shamans say that all sickness starts in the spiritand only later becomes physical. Using tools including shamanic journeying and dancing we will seek access to the beyond and to whatever healing is needed to bring us health and fitness both individually and collectively. Overcoming fear of death is a key to daring to live fully with heart. It is by committing to ourself that we will live fully, live to our best, put our whole self into whatever we have chosen to pursue…. that the most stunning results come to be achieved. And it is from that experience of daring to to go full-on that the greatest insight and development happens. Through Shamanic Journeying, ceremony, dance, we disappear into spirit, detaching from life’s ordinary challenges, able to let go and see through and past everyday issues to deeper patterns. We enter parallel realities where hidden patterns can be experienced and solutions to seemingly unsolvable problems can be accessed. 'Thank you very much for these past months & the journey round the wheel. I gained much from this and the group and it has been lovely to reconnect with you.... In deep appreciation of what you bring & gratitude for what these months have brought me. I do hope you will keep in touch.' ------------------------------------------------------------------------------------ October 27th -29th 10am – 6pm Saturday, 10am – 5pm Sunday At Clophill Centre, Shefford Road, Clophill, Beds MK45 4BT.  Residence (not included, book separately) available at Clophill or local B&B/ AirB&B etc.  Bring small share for light lunches.

This two-day course, led by Natasha Mann, will introduce students to the Art of Zouaq. Zouaq is a painting technique original to Morocco which creates arresting and powerful designs. Found painted onto ceilings, doors, furniture and wooden objects it is an integral part of the decoration of private homes and sacred spaces in Morocco. Students will also be given an introduction to the history of Zouaq and its different styles. Using the traditional techniques of egg tempera painting using hand ground natural pigments from earth and minerals, participants will choose their favourite design from a portfolio of Moroccan geometric patterns (ideally drawn during the prior Moroccan Geometric Pattern course (17 Sept. 2021) to create a stunning painting on wood to take home
